Torque Control (Spec: E Or Later Only) - YASKAWA CIMR-F7A Instruction Manual

Torque Control (SPEC: E or Later Only)

With flux vector control, the motor's output torque can be controlled by a torque reference from an analog
input. Set d5-01 to 1 to control torque.

Number
0: Speed control (C5-01 to C5-
07)
1: Torque control
This function is only available in
Torque con- flux vector control method. To
d5-01
trol selection use the function for switching
between speed and torque con-
trol, set to 0 and set the multi-
function input to "speed/torque
control change."
Set the torque reference delay
time in ms units.
This function can be used to
Torque refer- adjust the noise of the torque
d5-02 ence delay control signal or the responsive-
time ness with the host controller.
When oscillation occurs during
torque control, increase the set
value.
Set the speed limit command
method for the torque control
method.
Speed limit 1: The analog input limit from
d5-03
selection a frequency reference (see
b1-01)
2: Limited by d5-04 constant
setting values.
Set the speed limit during torque
control as a percentage of the
maximum output frequency.
This function is enabled when
d5-04 Speed limit d5-03 is set to 2. Directions are
as follows.
+: Run Command direction
-: Run Command opposite
direction
Set the speed limit bias as a per-
centage of the maximum output
frequency.
Speed limit
d5-05 Bias is given to the specified
bias
speed limit. It can be used to
adjust the margin for the speed
limit.
