H13 Auto-restart (Restart time)
Instantaneous switching to another power line (When the
power of an operating motor is cut off or power failure occurs)
creates a large phase difference between the line voltage and
the voltage remaining in the motor, which may cause electrical
or mechanical failure. To rapidly switch power lines, write the
remaining voltage attenuation time to wait for the voltage
remaining in the motor to attenuate. This function operates at
restart after a momentary power failure.
- Setting range: 0.1 to 5.0s
H13 RESTART
NOTE: *1) Operation switch on control panel
*2) Use “X4” when current input is used.
*3) Take countermeasures against momentary power failure
for a signal from “REMOTE”.
*4) T0 is an electronic timer with reset terminal.
*5) AX terminal function is used to make MC2 OFF after
deceleration to a stop.
*6) Retry condition is determined depending on electric facility.
The cut-off switch CP2 should be prepared in this circuit.
