Immediate power-down
• Identification of locations having abnormality by the number of times the LEDs flash
On Shutdown and power-down
Shutdown
• Operation: When the microcomputer detects any abnormality, it forcibly shuts the unit off.
• LED indication: The LED flashes in green.
Note: The LED flashes regardless of the FRONT INDICATOR setting on the Integrator menu.
Power-down
• Operation: When the unit is in emergency status, a protection circuit is activated, and the power is shut off.
• LED indication: The LED flashes in red.
∗
1: If the unit cannot identify which protection circuit was activated, even if a power-down had been detected, the red LED may flash 15 times.
∗
2: If 15 times blink of a power-down cannot be specified, the drive processing IC exists.
See "4.PANEL PD" on page 98 and "GPD: Power-down information" on page 116.
