Hey John. Are you still using the LENZE 534 driver module? I'm not sure if motor can handle 12.2 Amps as Boxford set max to 8 Amps ,,,but learning learning. My LENZE 534 has stopped working and I am trying to trace fault. I had to replace capacitor across the mains input but it still does not function. I am trying to work out how the Simplatron DCVT-2 interface board controls the input of the LENZE driver. I have traced fault to output of DCVT-2 board. I just need to know if the DCVT-2 generates the 10v reference from A (white wire) on DCVT-2 connected to Pin 9 labelled +VCC in Useless LENZE manual. Can you disconnect white wire and report if 3 to 10 volts dc is present between A and C terminals on DCVT-2 board or that 10 volts is generated on pins 7 and 9 on LENZE board---with white wire disconnected. That would help a lot thanks.

I have checked that 180 volts is present and the IXYS Half Controlled Single phase Rectifier Bridge is fine and waiting for dual Gate control to start motor.
