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.
(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
