This function is available in
Closed Loop Vector control
mode only. To use the func-
tion for switching between
speed and torque control, set
d5-01 to 0 and set the multi-
function input to “speed/
torque control change.”

erence delay
time
Sets the torque reference delay
time.
It can be used to prevent oscil-
lations caused by signal noise
or to increase or decrease the
responsiveness.
When oscillation occurs dur-
ing torque control, increase
the set value.

Speed limit
Sets 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.

bias
Sets the speed limit bias as a
percentage of the maximum

The bias is applied to the spec-
ified speed limit. It can be
used to adjust the margin for
the speed limit.

Speed/
torque con-
trol switch-
ing timer
Sets the delay time from
inputting a “speed/torque
control change” (Digital input
from On to OFF or OFF to
ON) until the control is actu-
ally changed.
This function is enabled when
the multi-function input
“speed/torque control change”
is set. The analog inputs val-
ues are hold from the point,
when the “speed/torque con-
trol change” is activated.
