Encoder Synchronization
The Encoder Synchronization process determines the correct A/B encoder channel phasing and
direction of rotation for PM motors and immediately follows either method of learning the
encoder pole position.
Perform the following for encoder synchronization.
Set Encoder Synchronization LL07 to Start.
Follow the directions on the drive keypad.
NOTE
: The drive runs the elevator and swaps the phasing and direction of the A/B
channels as needed.
Operation
Run the car and complete the checklist during the verification process.
No Faults
Make sure the car is moving without triggering a fault either on the Smartrise SRU Board or the
drive. If the SRU Board displays a drive fault, look at the drive to see what the fault is. See Drive
Fault / Encoder Fault for troubleshooting drive fault.
Proper Direction
Make sure the car is moving in the same direction as the control switch on the Run Bug. See
Wrong Direction for troubleshooting proper direction faults.
At Speed
Make sure the car is moving at the proper inspection speed (approximately 50 fpm). See Car
Moving to Slow or Rough for troubleshooting at speed faults.
Under Control
Make sure that the car is moving under full control. The car should stop when commanded
from the Run Bug. Verify that the car runs with no faults for 10 seconds or more. See Brake Not
Lifting for troubleshooting under control faults.
