Functions
Speed/Position Switching Function (SPD)
Allocate 73 (SPD) to one of the multi-function inputs.
While the SPD terminal is turned on, the current position counter is retained at "0". Therefore, if the
SPD terminal is turned off during operation, the Inverter shifts to the position control mode. (Speed/
Position switching)
At this time, if the position command is "0", the Inverter immediately stops.
(Hunting may occur, depending on the position loop gain setting.)
While the SPD terminal is turned on, the Inverter runs in the direction based on the RUN command.
When shifting from speed control to position control, be careful about the polarity sign of the RUN
command.
