Fig. 3 present invention a kind of elevator main controller, synchro traction machine and the volume of the anti-locking apparatus of elevator synchro traction machine driving
Code device attachment structure schematic diagram.The figure is by taking ABZ incremental encoders as an example.The type encoder generally has three tunnel signal outputs (poor
The road signals of Fen You six)：A, B and Z, typically using Transistor-Transistor Logic level, A pulses are preceding, and B pulses differ 90 degree, often enclosed in rear, A, B pulses
A Z pulse is sent, can be as referring to mechanical zero.Encoder is defined as shaft end and sees that encoder is clockwise turned to just in the example
Turn, using the advanced B of A as 90 ° sentenced to.
When it is Positive work that the advanced B of default label A of master controller 1, which are 90 °,.In master controller 1 and synchro traction machine 2
In the case of UVW wiring is correct, UVW vectors electricity can be sent during driving 2 Positive work clockwise of synchro traction machine of master controller 1
Pressure, if this group of UVW vector voltage is defined as into forward direction, encoder 3 will be beamed back with motor Positive work to master controller 1

Give tacit consent to the advanced B of A with master controller 1 just opposite for 90 ° of label information.Therefore power line UVW physical cabling is not being changed
In the case of, it is only necessary to by the advanced B of the A of default label in master controller 1 it is the definition that 90 ° are Positive work, is changed to acquiescence
A is the definition that 90 ° are Positive work before the B ultrasound of mark, thus reaches the effect of one " two negatives make a positive ", hereafter master controller
1 can just detect that direction, as foundation, positive UVW is sent to rotate forward needs according to motor according to encoder 3 to synchro traction machine 2
Voltage vector.Here it is the present invention needs the purpose actually reached.Prevent elevator traction machine power cable by this method

Schematic diagram.In-site installation personnel are easily dynamic what is connected between the UVW three-phases of elevator traction machine 2 and the UVW three-phases of master controller
Line of force intersection is reversed, and when now master controller 1 sends UVW voltage vectors according to acquiescence forward direction, elevator traction machine 2, which can be inverted, to be caused
Runaway accident occurs for lift car 7.So being 90 ° and acquiescence when master controller 1 detects the B pulse advance A pulses of encoder
When the A pulse advance B pulses of mark are opposite for 90 ° of rotation direction.Master controller 1 can be by the silent of the encoder 3 marked
It is positive to recognize setting to be changed to B pulse advance A pulses to be 90 °.So master controller 1 can still can be in power cable reversal connection
In the case of obtain actual motor steering foundation so that sending correct UVW vector voltages ensures that elevator runs well to prevent
Runaway accident occurs for elevator.
