Performance Adjustments
Stalling Attempting to Lift Load
If the motor stalls as it attempts to lift the load,
then until resolved, try the following (in order):
1. Increase the Torque Boost Gain
parameter
2. Adjust the Motor Stator Resistance
parameter
3. Adjust the Motor Mid Voltage parameter
Note: if no performance change is observed
after any one step, set any changed value(s)
back to the original value(s) before
proceeding onto the next step.
Increase the Torque Boost Gain Parameter
•
The Torque Boost function is defaulted
off (TORQ BOOST GAIN (A1)= 0).
•
Increase the TORQ BOOST GAIN (A1)
in 0.1 intervals and observe
performance.
Adjust the Motor’s Stator Resistance
•
Measure the stator resistance by
completing the procedure detailed on
page 16.
•
If still stalling after measuring stator
resistance, additionally increase
STATOR RESIST (A5) parameter
(increase increments of 0.1 and observe
performance)
Adjust the Motor Mid Voltage Parameter
•
Complete the Mid-volts Adjustment
Procedure detailed on page 16.
•
If still stalling after completing mid-volts
adjustment procedure, additionally
increase MOTOR MID VOLTS (A5)
parameter (increase increments of 0.5
and observe performance)
•
Note: Avoid increasing the MOTOR MID
VOLTS (A5) parameter too high, since
this effects stopping performance (i.e.
coming into the floor too fast) or can
create Overcurrent Faults
