Standby mode

Standby mode is intended for times in which operation is paused. The significant difference between disconnection of the DC 24 V supply voltage and standby mode is that switching from standby mode to operation only takes approx. 500 ms, and that bus communication is maintained. This allows for reducing the energy consumption even in short pauses.

A requirement for activating standby mode is that all output stages are inhibited and FCB 58 is not activated. Standby mode can be activated via a previously parameterized digital input or via a process data bit. All axis modules connected to a regenerative power supply module will also be automatically switched to standby mode.
