Speed Limit (torque=0) Band
Program ⇒ To r que ⇒ Torque Speed Limiting
The system has the ability to limit the amount that the speed may vary as a
function of a changing load while operating in the Torque Control mode. This
parameter sets a plus-or-minus value (range) for the Speed Limit Torque Level
(
F431).
Direct Access Number — F432
Parameter Type — Numerical
Factory Default — 0.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — Max. Freq. (F011)
Units — Hz
Rotation in Specified Direction ONLY
Program ⇒ To r que ⇒ Torque Speed Limiting
This parameter Enables/Disables the Forward Run or Reverse Run mode.
If either direction is disabled, commands received for the disabled direction will
not be recognized.
If both directions are disabled, the received direction command will determine
the direction of the motor rotation.
