Parameter Adjust the output torque (current) of the motor
FR-E700 SC EC/ENE 6 - 51
NOTES When the load is heavy or the acceleration/deceleration time is short, stall prevention is activated
and acceleration/deceleration may not be made according to the preset acceleration/deceleration
time. Set Pr. 156 and stall prevention operation level to the optimum values.
In vertical lift applications, make setting so that the fast-response current limit is not activated.
Torque may not be produced, causing a drop due to gravity.

CAUTION:
●
Do not set a small value as the stall prevention operation current. Otherwise, torque gener-
ated will reduce.
●
Always perform test operation.
Stall prevention operation during acceleration may increase the acceleration time.
Stall prevention operation performed during constant speed may cause sudden speed
changes.
Stall prevention operation during deceleration may increase the deceleration time, increas-
ing the deceleration distance.
