■ d5-01: Torque Control Selection
No.

Name Description
Default

d5-01
(029A)
Torque Control
Selection
Sets the drive for torque control or speed control.
0
(0, 1)
0 : Speed Control
Enables Speed Control. The drive controls the speed as specified by C5-01 to C5-07 [Speed Control (ASR) Setting
Parameters].
Also use this setting when you use H1-xx = 71 [MFDI Function Select = Torque Control] to change between
Speed Control and Torque Control.
1 : Torque Control
Always enables Torque Control.
■ d5-02: Torque Reference Delay Time
No.
(Hex.)
Name Description
Default
(Range)
d5-02
(029B)
Torque Reference
Delay Time
Sets the primary delay time constant for the torque reference filter.
Determined by A1-02
(0 - 1000 ms)
This parameter applies a primary delay filter to the torque reference signal to stop oscillation caused by a torque
reference signal that is not stable. This also helps remove electrical interference from the torque reference signal
and helps adjust the responsiveness between host controllers.
If oscillation occurs during Torque Control, increase the setting value. If the setting value is too high,
responsiveness becomes unsatisfactory.
■ d5-03: Speed Limit Selection
No.
(Hex.)
Name Description
Default
(Range)
d5-03
(029C)
Speed Limit
Selection
Sets the torque control speed limit method.
1
(1, 2)
1 : Active Frequency Reference
The enabled frequency reference set in b1-01 [Frequency Reference Selection 1] or b1-15 [Frequency Reference
Selection 2] will be the speed limit. The drive applies the values set in C1-01 to C1-08 [Acceleration/Deceleration
Times 1 to 4] and C2-01 to C2-04 [S-Curve Time @ Start/End of Accel] as speed limits.
2 : d5-04 Setting
The speed limit is the value set in d5-04.
■ d5-04: Speed Limit
No.
(Hex.)
Name Description
Default
(Range)
d5-04
(029D)
Speed Limit
Sets the speed limit during Torque Control as a percentage of E1-04
[Maximum Output Frequency]. Set d5-03 = 2 [Speed Limit Selection = d5-
04 Setting] before you set this parameter.
0%
(-120 - +120%)
The speed limit is a positive value when it is in the same direction as the Run command. The speed limit is a
negative value when it is in the opposite direction of the Run command.
■ d5-05: Speed Limit Bias
No.
(Hex.)
Name Description
Default
(Range)
d5-05
(029E)
Speed Limit Bias
Sets a bias to the speed limit as a percentage of E1-04 [Maximum Output
Frequency].
