MOTOROLA MVME705B Pulse output card

Initial Preparation Before attempting to check the alignment, perform the following set-up: 1. Make sure the mains power to the drive is switched OFF. 2. Connect three 1k , 1W resistors to each motor phase winding as shown in Figure C-1. 3. Disconnect the main motor cable from the drive, but leave the resolver cable connected. 4. Provide the +24V DC supply to the drive’s controller. 5. Set SV parameters P33=1 (torque control) and P44=1 (override undervoltage error during installation). 6. Provide a +5V signal across the AN1 differential input (X8 pins 1 & 2). 7. Arrange for the motor shaft to be driven at 50 rpm in either a CW (Clockwise direction) or CCW (Counter Clockwise) direction

Procedure 

This procedure allows you to check the alignment of the resolver relative to the motor. If the measurements indicate mis-alignment the angular setting of the resolver will need to be adjusted and re-checked by repeating this procedure. 1. With a +5V signal between X8/1 & X8/2 and theor turning CCW, use the oscilloscope to measure the voltage across the ‘U’ phase resistor (Vu). This voltage must be the same phase as the voltage appearing at the U-phase monitor ouput (X9/5). Also the voltage Vv must be the same phase as the voltage appearing at the V-phase monitor output (X9/6).
