Range
This functions as torque limit level under
real sensorless vector control.
* For the 3.7K or less, the initial value changes
from 150% to 200% when V/F control or
0 to 400%
advanced magnetic flux vector is changed to
*
real sensorless vector control or vector control.
Refer to page 91 for stall prevention
operation level.

and control)
Constant torque limit (torque limit and

control)
Internal torque limit
0 Parameter-set torque limit operation is
performed.
External torque limit
1 Torque limit based on the analog input
from terminal 1 and 4.

Set the torque limit level for forward
0 to 400%
rotation regeneration.
9999 Pr. 22 value is used for limit.
Set the torque limit level for reverse
0 to 400%
rotation driving.
9999 Pr. 22 value is used for limit.
Set the torque limit level for reverse
0 to 400%
rotation regeneration.
9999 Pr. 22 value is used for limit.
When the torque limit selection (TL) signal
0 to 400% is on, the Pr. 815 value is a torque limit
value regardless of Pr. 810.
9999 Depending on Pr. 22 setting
Set the torque limit value during
0 to 400%
acceleration.
9999 Same torque limit as at constant speed
Set the torque limit value during
0 to 400%
deceleration.
9999 Same torque limit as at constant speed
This function can make an alarm stop if the
torque limit is activated to stall the motor.
0 to 200%
Set the output torque at which an alarm
stop is made in Pr. 874 .
