Magnetek DSD412 Drive Self-Tune Procedure
Perform the Magnetek DSD412 drive self-tune procedure as follows.
Place a jumper from LPR on the DIN rail to SAFE.
Put the NVRAM Protected switch in the Not Protected position.
Perform PCU DIAGNOSTICS Function 998 to verify armature and field circuitry.
Perform SELF-TUNE PARAMETER TEST Function # 997. The drive should display PASS
after a few seconds. Set Parameter #2 to ON.
Remove the jumper and perform Function #994 to permanently save the changed
values.
Verify the Smartrise MR board LCD is not showing an active fault as indicated by a
flashing Red LED, and it displays Construction Mode.
Close the Run Bug Stop switch.
Command the Car to move.
Verify the brake is picking/holding after a valid run command is given.
Verify the brake is dropping once the command is removed.
Verify the timing and operation of the brake to ensure the motor is not running through
the brake prior to it picking.
Is the brake inoperative?
a.
If the brake is operative, go to step 13.
b.
If the brake is inoperative, check the following:
•
Check for DC voltage between points K1 and K2 on the Machine Room DIN rail.
•
Verify this voltage is also at the brake coil when commanded to pick.
•
Ensure this voltage corresponds to the voltage the brake coil is rated for.
•
If problems persist, contact Smartrise for assistance.
The encoder feedback may be out of phase upon first power-up. This may cause the
motor to run faster than commanded and/or give drive fault 408/98. Is the encoder
feedback out of phase?
