Action below by the motor-driven system of Fig. 3 key diagram 1.
When AC power 1 operate as normal, by the action of AC/DC converter 3, the correct high-voltage DC power supply 2 of supplying with on DC power bus 4.By the action of DC/DC converter 6, the low-voltage dc power supply 5 (regular event 31 among Fig. 3) that correct supply electronic circuit is used on central control unit 7.At this moment, the revolution speed control device 8 that batches usefulness makes induction motor 11 rotations with predetermined rotational speed, makes the reel rotation that is connected a plurality of spindles in the rotating shaft.On the other hand, revolution speed control device 9-1, the 9-2 of each spindle ..., 9-N respectively with required rotary speed make brushless motor 12-1,12-2 ..., 12-N rotation, make the spindle rotation of each spindle.When so just can on each spindle, batch spinning, in this road, spinning is twisted.
In addition, AC power 1 is in normal work period, central control unit 7 is by the induction motor 11 of communication bus 14 when each revolution speed control device 8,9 notice outage, the deceleration of brushless motor 12, and each revolution speed control device 8,9 is accepted the ratio of this notice back setting deceleration control.
Disconnected or be reduced to assigned voltage when following (cutting off the power supply 32 among Fig. 3) when AC power 1, the outage detection device is exported outage detection signal 16 immediately.The revolution speed control device 9 that each spindle is used when receiving outage detection signal 16 immediately with the control that reduces speed now of the ratio of above-mentioned setting.Brushless motor 12 is reduced speed now.At this moment the deceleration that the inertia rotation of deceleration (33 among Fig. 3) specific speed control device when not having control causes also wants big, thereby the rotary system of spindle is braked.The energy of this braking is transformed to electric energy with brushless motor 12 as generator, is regenerated as high-voltage DC power supply by synchronous inertia diode.
As shown in Figure 3, no matter whether the voltage of high-voltage DC power supply AC power reduces all from the rotary system of spindle obtain regenerated electric power and keep voltage.The rotary system inertia ratio of spindle is bigger, and for example carries out 20,000 high speed rotating that change, and because the platform number is many, so can obtain enough regenerated electric powers.Simultaneously, at the voltage of accepting also to keep on the DC/DC converter 6 that high-voltage DC power supply supplies with the low-voltage dc power supply that electronic circuit uses.Thereby central control unit 7 can proceed to monitor the action of motor state etc.
On the other hand, batch the induction motor 11 of usefulness because the inertia ratio of the rotary system of reel is less, so if revolution speed control device does not have control, then rotary speed descends rapidly.Do not batch the spinning of state for reel, spindle is excessively twisted for this reason, and fracture of wire will take place.But, as mentioned above owing to still keep high-voltage DC power supply and low-voltage dc power supply, so the revolution speed control device 8 that batches usefulness when reception outage detection signal, the ratio with above-mentioned setting begins to carry out deceleration control immediately.Like this, induction motor 11 Be Controlled are slowed down.At this moment deceleration (34 among Fig. 3) can be also milder than being reduced by the caused speed of above-mentioned inertia.Carried out synchronization settings at this, so that the spinning speed on the twisting speed of spindle and the reel is complementary.After this, soon, high-voltage DC power supply also stopped after the rotary system of spindle stopped, but during this period because the rotary system of the rotary system of spindle and reel is to slow down synchronously, so can avoid the excessively situation of twisting of spinning, prevented fracture of wire.
For example, when supply voltage did not recover yet through 1 second,, but, begin normal motor driven once again when 1 second during with interior recovery then having a power failure halt system fully.In the present embodiment, owing to supply with the control power supply of central control unit 7 by DC power bus 4, during instantaneous power failure, also can carry out the state value monitoring of said motor continuously by DC/DC converter 6.
According to formation of the present invention, even instantaneous power failure takes place, revolution speed control device not only, and can not use back-up source just can guarantee the control power supply of external equipment.Said external equipment comprises from revolution speed control device and is taken into device that motor status signal (rotational speed signal etc.) monitors and the device that necessary CRANK PULSES of revolution speed control device regular event and speed command signal are sent often often.In addition, revolution speed control device comprises that at least the converter that direct current is become interchange partly reaches the control circuit that the switch element of this converter part is carried out switch.
In addition, when detecting outage,, DC power supply is made electric power regeneration, so the instantaneous power failure compensation that the AC/DC converter needn't maximize and just can carry out 0.5～1 second by to the motor deceleration control.
Describe the 2nd embodiment of the present invention with reference to the accompanying drawings in detail.
At this, motor-driven system of the present invention is applicable to the spinning coiling system of band godet.This system has a plurality of spindles, carries out on each spindle in the spinning coiling, by godet spinning is extended in this road.The rotating ratio of a plurality of rollers that godet is sent by curled hair, the tension force that spinning is stipulated.In addition, also have heater is housed in godet, the situation that the spinning of batching is heated.
As shown in Figure 4, the motor-driven system in the spinning coiling system of band godet is installed in respectively in the GR control panel 40 and bobbin-winding machine control panel 50 of control godet.In GR control panel 40, be equipped with: with the revolution speed control device 41,42 of three-phase alternating-current supply 60 as the motor that is used for drive controlling first roller and second roller 45,46 of input; By CRANK PULSES line 61 often CRANK PULSES send sequencer (シ-ヶ Application サ) PLC (CRANK PULSES output device) 43 of each revolution speed control device 41,42 to; And will be transformed to the converter 44 of electronic circuit from the DC power supply that the AC/DC transformation component 42a in the revolution speed control device 42 takes out with DC power supply DC/DC.In revolution speed control device 41, be provided with AC/DC transformation component 41a.
In bobbin-winding machine control panel 50, be provided with: as input 4 motors are carried out the revolution speed control device 51 of drive controlling respectively with three-phase alternating-current supply 60; Report to the police and handle and the sequencer PLC52 of the action control of bobbin-winding machine etc.; By speed command signal line 63 to the speed control unit of revolution speed control device 51 output speed command signals (speed command signal output device) 53 often; The high-voltage DC power supply that AC/DC transformation component 51a in revolution speed control device takes out is transformed to the DC/DC converter 54 of the electronic circuit of sequencer PLC52 and speed control unit 53 with DC power supply.4 motors are made up of the motor 55 that traverses, engagement shaft drive motor 56, Spindle Motor 57,58.Speed probe 59 is installed on each motor, and the signal of speed probe 59 is input in the speed control unit 53.
PLC 43 and PLC52 interconnect by alarm signal/driving stop signal line 62.
The following describes the action just often of this motor-driven system.Supply with each revolution speed control device 41,42,51 from the voltage of three-phase alternating-current supply 60 outputs.Each revolution speed control device 41,42,51 is equipped with AC/DC transformation component 41a, 42a, 51a in all, and the DC/DC converter that the high-voltage DC power supply of this AC/DC conversion further is transformed to the low-voltage dc power supply of control usefulness also is housed.Drive inner control circuit (circuit of using for switch) by this control with low-voltage dc power supply.Speed control unit 53 detects the rotary speed of each motor by the signal of the speed probe installed on each motor 59 outputs, and these rotary speeies are compared with predefined desired value, calculates speed value.Then, often this speed command signal is exported to revolution speed control device 51 by speed command signal line 63.In the example of Fig. 4, in each revolution speed control device 41,42,51 AC/DC transformation component 41a, 42a, 51a are housed all.But example that also can image pattern 1 is such, all connects each revolution speed control device 41,42,51 on the dc bus of an AC/DC transformation component.
On the other hand, each revolution speed control device 41,42,51 inside is separately installed with the outage detection device, often outage is monitored, and also can cut off the power supply local a detection, and the outage detection signal is transferred to each revolution speed control device 41,42,51.The following describes the action when detecting outage.
This motor-driven system makes when instantaneous power failure and batches action and do not stop, and proceeds, and action is stopped.At first, when instantaneous power-off, AC power disconnects or when being lower than assigned voltage, after being detected by outage detection devices of installing in each revolution speed control device 41,42,51, each motor is decelerated to than the predefined rotary speed lower than normal value remain in operation.For example when AC power at 1 second during with interior recovery, the rotary speed that returns to often remains in operation.In the time can not recovering, system all stops at this point.Like this, when detecting outage,, on DC power supply, make electric power regeneration because each motor is slowed down.So power failure compensation that the maximization of AC/DC transformation component just can be carried out 0.5～1 second.Because by the control of GR control panel 40 and bobbin-winding machine control panel 50, synchronous, the deceleration of each motor is so the tension force that is added in the instantaneous power-off process in the spinning can suitably be kept.In addition, by the deceleration of each motor, AC/DC transformation component 42a, the last energy of 51a in the revolution speed control device obtains regeneration.Therefore sequencer 43,52 can obtain enough electric power continuation actions.
In the present embodiment, also can carry out the computing of the speed value on the speed control unit 53 continuously and revolution speed control device 51 is sent speed command signal even instantaneous power-off takes place.Also can carry out the action control of the warning processing undertaken by sequencer 52 and bobbin-winding machine continuously.
