d5-06
Speed/torque control
switching timer
Sets the delay time from inputting
the multi-function input “speed/
torque control change” (from ON to
OFF or OFF to ON) until the con-
trol is actually changed, in ms units.

This function is enabled when
the multi-function input “speed/
torque control change” is set. In

Ref Hold Time
torque control change is set. In
the speed/torque control switch-
ing timer, the three analog inputs
hold the values of when the
“speed/torque control change”
changes. Always be sure to allow
time for this process to finish
completely.
