Note:
The lower value is enabled when both
L7-01 to L7-04
and either analog inputs or communication option torque limits set torque limits
for the same quadrant.
As in the following example of parameter settings, the torque limit for quadrant 1 is 130% and the torque limit for quadrants 2, 3, and 4
is 150%.
Settings:
L7-01
= 130%,
L7-02
,
L7-03
,
L7-04
= 200%, MFAI torque limit = 150%

Forward Torque Limit
Sets the torque limit value for forward motoring as a percentage, where motor rated torque is the
100% value.
200%

Note:
•
Use this method to set the torque limit and enable the lower torque limit:
–
Set
H3-02
,
H3-06
, or
H3-10 = 10, 15 [MFAI Function Select = Forward, Reverse/Regenerative Torque Limit]
.
–
Use a communication option to set the torque limits
•
You must think about drive capacity when a large quantity of torque is necessary. If you set the value too high, the drive can detect
oC
[Overcurrent]
.
•
If you set the value too low with large loads, the motor can stall.
