Adjustment Procedure Use the following procedure to adjust the parameters on the
Configuration > Drive > Safety tab used to generate the SCR Loop Over Current Fault.
Rated loop over-current
1. With a full load in the car, run the car up. On the Operational Status tab, observe Arma-
ture current while the car is traveling at steady speed (not accelerating or decelerating).
Note
Full load up is preferable, but if not possible, run empty car down.
2. Set Rated loop over-current (Drive > Safety tab) 5 to 10 amps greater than the observed
steady speed Armature current.
Loop over-current fault time
1. On the Virtual Oscilloscope, set Test point 1 = Over Current Power and Test point 2 =
Over Current Power Threshold.
2. Set Loop over-current fault time (Drive > Safety tab) = 30 seconds.
3. With a full load in the car, run the car up (see Note above). It is best to make runs that
just reach Contract speed momentarily before decelerating and stopping. Observe the
oscilloscope. The objective is to adjust the Loop over-current fault time parameter until
the maximum Over Current Power is 50% to 75% of the Over Current Power Threshold.
4. Adjust the Loop over-current fault time parameter and repeat step 3. Decreasing the
Loop over-current fault time decreases the Over Current Power Threshold and vice
versa.
5. As a final test, make a full hatch run up and down.
