All Modes
Sets the operation time (U1-04) required before Mechanical Weakening
Detection is active.
L7: Torque Limit
V/f OLV
Sets the torque limit value as a percentage of the motor rated torque.
Four individual quadrants can be set.
Output Torque

REV
L7-02
V/f OLV
Sets the integral time constant for the torque limit. Increase the setting for
faster torque limit response.
V/f
OLV
0: Proportional control (changes to integral control at constant speed).
Use this setting when acceleration to the desired speed should take
precedence over the torque limit.
1: Integral control.
Set L7-07 to 1 if the torque limit should take precedence.
V/f OLV
0: A delay time is disabled
1: A delay time is enabled
V/f OLV
Sets the mode for the regenerative torque limit.
0: Standard mode (torque limits entered from all analog inputs and
through communications effective)
1: Independent mode (only the torque limits set with L7-03, L7-04, and
regenerative torque limit effective (H3-
L8: Drive Protection
All Modes
An overheat pre-alarm will occur if the thermistor temperature exceeds the
level set in L8-02.
All Modes
0: Ramp to stop. A fault is triggered.
1: Coast to stop
2: Fast Stop. Decelerate to stop using the deceleration time in C1-09. A
fault is triggered.
3: Continue operation. An alarm is triggered.
4: Continue operation at reduced speed as set in L8-19.
Note:
0 to 2 are recognized as faults, and 3 and 4 as alarms.
All Modes
0: Disabled
1: Enabled (triggered by a single phase loss)
2: Enabled (triggered when two phases are lost)
Triggered when the output current falls below 5% of the drive rated
current.
Output phase loss detection can mistakenly be triggered if the motor rate
current is very small comparing with the drive capacity. Disable this
parameter in such case.
