Torque Control
Selection 0: Speed control (C5-01 to C5-07)
1: Torque control
This function is only available in Flux
Vector Control method. To use the func-
tion for switching between speed and
torque control, set to 0 and set the multi-
function input to “speed/torque control
change.”
0 or 1 0 No No No A 29AH 6-108
Torq Control Sel
d5-02
Torque Reference
Delay Time Set the torque reference delay time in ms
units.
This function can be used to adjust the
noise of the torque control signal or the
responsiveness with the host controller.
When oscillation occurs during torque
control, increase the set value.

Speed Limit
Selection Set the speed limit command method for
the torque control method.
1: The analog input limit from a fre-
quency reference
2: Limited by d5-04 setting values.

Speed Limit Sel
d5-04
Speed Limit Set the speed limit during torque control
as a percentage of the maximum output
frequency.
This function is enabled when d5-03 is
set to 2. Directions are as follows.
+: Run Command direction
-: Run Command opposite direction
-120 to
+120
0% No No No A 29DH 6-108

Speed Limit Bias Set the speed limit bias as a percentage of
the maximum output frequency.
Bias is given to the specified speed limit.
It can be used to adjust the margin for the
speed limit.

Speed/Torque
Control
Switchover Timer Set the delay time from inputting the
multi-function input “speed/torque con-
trol change” (from on to off or off to on)
until the control is actually changed, in
ms units.
This function is enabled when the multi-
function input “speed/torque control
change” is set. In the speed/torque control
switching timer, the analog inputs hold
the values of when the “speed/torque con-
trol change” changes. Always be sure to
allow time for this process to finish com-
pletely.
