Relay Behavior after Bus Voltage Failure

If the bus voltage falls below 18 V, the drive can be switched to a parameterized state. The drive can either be defined as moving Up or Down or stopped (Stop), remain in the state it had before the failure (No reaction). At the same time, the current position of the relay is saved in the device.

Possible settings:

No reaction: the drive remains in its current state, i.e. it remains stationary or it continues to execute a current movement until the running times have elapsed.
Stop: the drive stops immediately.
Up: the drive moves up. If it was in the process of moving downwards, it stops and waits for a preset pause on reverse time of 300 ms before starting the upward movement.
Down: the drive moves down. If it was in the process of moving upwards, it stops and waits for a preset pause on reverse time of 300 ms before starting the downward movement.

IMPORTANT: If your settings may cause a change in direction in the event of a bus voltage failure (Up or Down settings), be sure to take the pause on reverse into account. This is preset to 300 ms for a bus voltage failure. The parameterized value for the drive is not active in this case. If the drive used requires a longer pause on reverse (see manufacturer specifications), then you must not use the settings Up or Down in order to avoid damage to the drive.
When making settings, note that the higher-level safety functions are not active during the bus voltage failure. In order to prevent this from resulting in damage, it is useful to make the settings in such a way that the drives are in a safe position during a bus voltage failure.
