■ d5-01: Torque Control Selection
No.
(Hex.)
Name Description
Default
(Range)
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.
