4-3 Functions When Multi-function Feedback Option Board (3G3AX-PG01) Is Used •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.) Without determination time (C169) 7 With determination time (C169) Position command CP1 CP2 4 CP3 Functions Determination time (C169) Speed/Position Switching Function (SPD) •To perform speed control in the absolute position control mode, turn on this terminal. •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.
