Chapter 7 FUNCTIONS

4.Inverter maintains the position after the completion, and outputs the ‘position control completion (POK) signal’ after the set value of ‘delay time setting (P018). (Inverter drives the motor reverse and return to the required stop position in the case it exceeds the required stop position.)

5.When the ORT terminal is turned off, the inverter stops operation and the orientation mode is cleared.

(Note3) In case of using Z pulse, use 5V line driver type output for EZP-EZN input.

(Note 4): Action timing of when only the operation command is OFF during the orientation.

If only the operation command is OFF, the motor will stop (1). After that if the ORT terminal is OFF(2), POK signal output will be OFF (3).

(While ORT terminal is ON. Due to the orientation mode is running , even though only the operation command is OFF , the POK signal output (4) keep ON within the completion range.

(Action timing of when only the operation command is OFF during the orientation.)

(Note 5) Rotation speed of motor is zero but inverter is outputting to the motor. Don't touch the motor power line. Otherwise there is a danger of electric shock /Injury.
