6.3.7 Automatic Restart after Momentary Power Loss (n051)
When momentary power loss occurs, operation restarts automatically.
Setting Description
0 Not provided (Factory setting)
1
[
Continuous operation after power recovery within 2 seconds
2
=
Continuous operation after power recovery within control logic time
(No fault output. Restarts only while control power supply is ON.)
∗ Hold the Operation command to continue operation after recovery from a momentary power loss.
= When 2 is selected, operation restarts if power supply voltage reaches its normal level. No fault signal is output.
6.3.8. Soft-Start Characteristics (n023)
To prevent shock during machine starting and/or stopping, accel/decel can be performed in S-curve pattern.
Setting S-curve Characteristic Time
0 S-curve not provided
1 0.2 s (Factory setting)
2 0.5 s
3 1.0 s
Note: S-curve characteristic time is the time from accel/decel rate 0 to a regular accel/decel rate determined by the set
accel/decel time.
