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
Direct Access Number — F429
Parameter Type — Selection List
Factory Default — Fixed Direction
Changeable During Run — No
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 F431 is used.
Settings:
0 — Disabled
1 — VI/II
2 — RR
3 — RX
4 — RX2
5 — Setting (F431)
Direct Access Number — F430
Parameter Type — Selection List
Factory Default — Disabled
Changeable During Run — Yes
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 a value that is used if Setting (F431) is selected at F430.
The plus-or-minus value (range) for this setting may be set at F432.
Direct Access Number — F431
Parameter Type — Numerical
Factory Default — 0.0
Changeable During Run — Yes
Minimum — 0.0
Maximum — Max. Freq. (F011)
Units — Hz
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 (range) for the Speed Limit Torque Level
(F431).
Direct Access Number — F432
Parameter Type — Numerical
Factory Default — 0.0
Changeable During Run — Yes
Minimum — 0.0
Maximum — Max. Freq. (F011)
Units — Hz
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.
Direct Access Number — F433
Parameter Type — Numerical
Factory Default — 0.20
Changeable During Run — Yes
Minimum — 0.00
Maximum — 2.50
Units — Seconds
