0: Speed control (C5-01 to
C5-07)
1: Torque control
This function is only avail-
able in flux vector control
method. To use the function
for switching between speed
and torque control, 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
adjust the noise of the torque
control signal or the respon-
siveness with the host con-
troller. When oscillation
occurs during torque control,
increase the set value.
Set the speed limit command
method for the torque control
method.
1: The analog input limit
from a frequency refer-
ence
2: Limited by d5-04 constant
setting values.
Set the speed limit during
torque control as a percentage
of the maximum output fre-
quency.
This function is enabled when
d5-03 is set to 2. Directions
are as follows.
+: Run Command direction
-: Run Command opposite
direction
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.
