Parameter
Adjust the output torque (current) of the motor
FR-D700 SC EC
6 - 39
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 acti-
vated. Torque may not be produced, causing a drop due to gravity.
b
CAUTION:
●
Do not set a small value as the stall prevention operation current. Otherwise, torque
generated 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,
increasing the deceleration distance.
