a. Check TP1 +5V, TP3 +15V, TP4 -15V, Reference TP2 COM, TP5 +24V, reference
TP6 C_24V.
9. Verify all of the drive parameters are set according to the controller manufacturers
recommendations.
10. Close the F3, F4 fuse holders, and clip the meter leads on those same points. Set the meter
on DC voltage. Push the PCM relay in for about 1s (damage will occur if held in longer!!),
then release, the meter should read the line voltage x 1.41. Dropping slowly is normal, quick
is not a good condition.
11. Once, the drive has passed all of the steps, the drive is ready to run the auto tune. To start
the process, go to the selection ‘A4 AUTO TUNE MOTOR’. If it completes with no faults, then
go into the A4 menu and select the gain selection method ‘Use self-tune’, the drive is ready to
run the elevator.
12. Next, the field current can be adjusted.
a. In the A6 menu, there is forcing current, running current and standing current. The
forcing current may be on the motor N.P. or perhaps the field voltage is available (FFA
= FFV / Field R). After that step is complete, run the elevator from bottom to top at
100% contract speed, adjust the weak field amps until the armature volts measure
nameplate. Standing field can be set to 10 – 25% of the forcing current.
13. At balanced load run the elevator from bottom to top, then top to bottom. Look in the D1 menu
and locate the Estimated Inertia, enter this as the new inertia in the A1 menu.
