Note:
• When you switch between Torque Control and Speed Control, set d5-01 = 0 [Torque Ctrl Selection = Speed Control]. If d5-01 = 1
[Torque Control] and H1-xx = 13 at the same time, the drive will detect oPE15 [Torque Control Setting Error].
• If the Stop command is input, the drive will not apply the delay time set in d5-06. Torque Control will immediately switch to Speed
Control and ramp to stop.

Torque Ctrl Selection
Sets the drive for torque control or speed control.
0

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 = 13 [DI Function Select = Spd/Trq Switch] to change between Speed
Control and Torque Control.
1 : Torque Control
Always enables Torque Control.
■ d5-02 Torque Ref Delay Time
No.

(029B)
Torque Ref 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

Speed Limit Selection
Sets the torque control speed limit method.

(1, 2)
1 : Active Freq Reference
The enabled frequency reference set in b1-01 [Freq. Ref. Sel. 1] or b1-15 [Freq. Ref. Sel. 2] will be the speed
limit. The drive applies the values set in C1-01 to C1-08 [Accel Time 1 to Decel Time 4] and C2-01 to C2-04
[Jerk@Start of Accel to Jerk@End of Decel] as speed limits.
