DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an inverter device that controls a spinning frame drive motor and performs time-programmed operation of the speed of the spinning frame.

[Conventional technology]

Conventional inverter devices that perform this type of operation are configured with a separate time control circuit for speed program control consisting of a timer, relay, multi-stage speed setting device, sequencer, etc., and the command signal from the time control circuit is sent to a device specific to the inverter device. It is known to perform the required speed program operation by adding the speed control circuit to the speed control circuit of the above.

In order to achieve the above object, an inverter device for driving a spinning frame according to the present invention is an inverter device that performs time-programmed operation of the speed of a spinning machine, and uses a general-purpose inverter device as a pace to control circuitry of the general-purpose inverter device. An optional board dedicated to time control of the speed of the spinning machine is provided on the top, and includes a logic circuit for timer setting and program operation status display, and an A-D and D-A conversion circuit for analog input/output processing. Program contents of the control sequence for time control are stored in a ROM element of the general-purpose inverter control circuit together with a control program for the general-purpose inverter.

[Effect]

The timer function, sequencer function, multi-stage speed setting function, etc. in the program operation as described above can be converted into digital calculations by specifying the respective calculation programs.

The present invention provides for integrally storing various arithmetic programs necessary for time control for program operation as described above in a ROM element of the inverter device control circuit together with the various arithmetic programs in a general-purpose impark device, and furthermore, a storage board for the inverter device control circuit. By interlocking with the corresponding logic circuit on the optional board for time control provided above, necessary calculations are performed, thereby reducing the number and size of the various elements required for the time control. .
