Functions
When you input a multi-step position command, you can set the wait time until the terminal input is
determined. This prevents the transition status from being applied before it is determined.
You can adjust the determination time in multi-step speed/position determination time C169. If no
input is made during the time set in C169, the data is determined after the set time elapses. (Note
that the longer the determination time, the slower the input response.)
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.
