Accel/Decel Operation After Torque Limit

Program ⇒ Torque ⇒ Torque Limit Settings
In a Crane/Hoist application that is operating using a mechanical brake, this
parameter is used to minimize the del ay between the brake release and the
output torque reaching a level that can sustain the load.
This setting may reference time or the opera ting speed of the motor.
Settings:
0 — In Sync with Accel/Decel
1 — In Sync with Minimum Time
Direct Access Number — F451
Parameter Type — Selection List
Factory Default — In Sync with Accel/
Decel
Changeable During Run — Yes

Overcurrent Stall (F017) time settings.
Direct Access Number — F452
Parameter Type — Numerical
Factory Default — 0.0
Changeable During Run — Yes
Minimum — 0.0
Maximum — 1.0
Units — Seconds
