MOT LOAD CURVE
Sets the maximum allowable operating load of the motor.
• When set to 100%, the maximum allowable load is equal to the value
of parameter 9906

.
• Adjust the load curve level if the ambient temperature differs from
nominal.

ZERO SPEED LOAD
Sets the maximum allowable current at zero speed.
Value is relative to 9906

STALL FUNCTION
This parameter defines the operation of the Stall function. This
protection is active if the drive operates in the stall region (see figure)
for the time defined by 3012
STALL
TIME
.
0 =
NOT
SEL
– Stall protection is not used.
1 =
FAULT
– When the drive operates in the stall region for the time set
by 3012
STALL
TIME
:
• The drive coasts to stop.
• A fault indication is displayed.
2 =
ALARM
– When the drive operates in the stall region for the time set
by 3012
STALL
TIME
:
• An alarm indication is displayed.
• The alarm disappears when the drive is out of the stall region for
half the time set by parameter 3012
STALL
TIME
.
3011
STALL FREQUENCY
This parameter sets the frequency value for the Stall function. Refer to
Figure.
3012
STALL TIME
This parameter sets the time value for the Stall function.
3017
EARTH FAULT
Defines the drive response if the drive detects a ground fault in the motor or motor cables. The drive monitors for
ground faults while the drive is running, and while the drive is not running. Also see parameter 3023
WIRING
FAULT
.
0 =
DISABLE
– No drive response to ground faults.
1 =
ENABLE
– Ground faults display fault 16 (
EARTH
FAULT
), and (if running) the drive coasts to stop.
