Functions
Speed/Position Switching Function (SPD)
This function is used for speed control operation.
Allocate “73” (SPD) to any of the multi-function inputs.
While the SPD terminal is turned ON, the current position counter is retained at zero. The Inverter
shifts to the position control mode when the SPD terminal is turned OFF during operation. (Speed/
Position switching)
With the position command set to 0, the Inverter shifts to the stop operation when the SPD terminal
is turned OFF
(Hunting may occur, depending on the position loop gain setting.)
While the SPD terminal is turned ON, the Inverter runs in the direction specified by the RUN com-
mand. To shift from speed control to position control, be careful about the polarity sign of the RUN
command.
