Torque Command Mode Selection
Program Torque Torque Speed Limiting
This parameter specifies whether the torque command function is to be used in
one direction or both (F/R).
Settings:
0 — Fixed Direction
1 — F/R Permitted
Speed Limit (torque = 0) Center Value Reference Selection
Program Torque 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 the input terminal that will be used to control the allowable
speed variance.
If Setting (F431) is selected, the value setting at
Settings:
0 — Disabled
1 — VI/II
2 — RR
3 — RX
4 — RX2
5 — Setting (F431)
Speed Limit (torque = 0) Center Value
Program Torque 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 the targeted speed.
The plus-or-minus value for this setting may be set at F432.
Speed Limit (torque = 0) Band
Program Torque 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 for the Speed Limit Torque Level
(F431).
Speed Limit (torque = 0) Recovery Time
Program Torque 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 the response time of the system to torque change requirements.
