Software and hardware settings for backup hold time do not match. (for E0x series controllers)

Error handling: Motor power OFF.
Error reset: Possible.

Content: When RUN/HOLD is switched from “RUN” to “HOLD”, the setting for a 2-second delay before motor power is cut off does not match between the software and hardware.

Main causes:

1. A 2-second delay is set in the software, but no delay is set in the hardware.

2. No delay is set in the software, but a 2-second delay is set in the hardware.

3. A problem with the power sequence board.

Countermeasures:

1. To set a 2-second delay, set SW2-2 on the power sequence board to ON, and set [Effective backup time] to "Standard" under [2 Hardware settings] in auxiliary function 2021 [System settings 1].

2. To set no time delay, turn SW2-2 on the power sequence board OFF, and set [Effective backup time] to "None" under [2 Hardware settings] in auxiliary function 2021 [System settings 1].

3. Replace the power sequence board.
