6-3-5 Speed/Torque Control Switching Function
It
is possible to switch between speed control and torque control when
one of the multi-function inputs
(H1-01 through H1-06) is set to 71 (Speed/T
orque Control Change). Speed control is performed when
the input is OFF and torque control is performed when the input is ON.

H Setting the Speed/Torque Control Switching Timer
This
setting specifies the delay (0 to 1,000 ms) between a change
in the multi-function input (ON
→
OFF
or OFF → ON) and the corresponding change in the control mode. The timer setting is effective only
when 71 (Speed/Torque Control Change) has been set in one of the multi-function inputs (H1-01
through H1-06).
