d5 Torque Control
d5-01 Torque Control Selection
Selects between speed and torque control during flux vector operation (A1-03 = 3). Torque reference is set via analog input terminal
A2 or A3 when it is set for “torque reference” (H3-09 or H3-05 = 13, respectively). Torque reference is set as a percentage of motor
rated torque.
To switch between speed and torque control using a contact closure, set parameter d5-01 = 0 and set one of the multi-function
contact inputs to “71: speed/torque control change” (H1-0x = 71).
d5-02 Torque Reference Delay Time
Setting Range: 0 to 1000 ms
Factory Default: 0 ms
Sets the torque reference delay time to correct for noise in the torque control signal or the responsiveness with the host controller.
When oscillation occurs during torque control, increase the set value.
d5-03 Speed Limit Selection
Sets the speed limit command method for the torque control method.
d5-04 Speed Limit
Setting Range: -120 to 120 %
Factory Default: 0 %
Sets the speed limit during torque control as a percentage of the maximum output frequency (E1-04). This function is enabled
when d5-03 is set to 2. Directions are as follows:
+ run command direction
- run command opposite direction
d5-05 Speed Limit Bias
Setting Range: 0 to 120 %
Factory Default: 10 %
Sets the speed limit bias as a percentage of maximum output frequency (E1-04). Bias is given to the specified speed limit. It can
be used to adjust the margin for the speed limit.
Setting Description
0 Speed Control (factory default)
1 Torque Control
Setting Description
1 Analog Input (factory default) - Limited by the output of
the soft starter (b1-01 selection and active acceleration /
deceleration and S-curve settings.)
2 Program Setting - Limited by d5-04 setting
