 Documentation for the standard device
Observe the safety instructions and information on residual hazards.
 Note!
Establishing communication
In order to establish communication via an externally supplied communication module,
the standard device must be switched on as well.
For further communication of the externally supplied module it is not relevant whether
the standard device is switched on or not.
Protection against uncontrolled restart
After a fault (e.g. short-term mains failure), it is sometimes undesirable or even imper-
missible for the drive to restart.
The restart protection is activated in the Lenze setting of the Inverter Drives 8400.
The restart behaviour of the inverter can be set via C00142 ("auto-start option"):
• C00142 = 9 (Lenze setting)
• The inverter remains inhibited (even if the fault is no longer active).
• Bit 0 (inhibit at power-on) and bit 3 (inhibit in the case of undervoltage) are set.
• The drive restarts in a controlled mode through explicit controller enable: LOW-
HIGH edge at digital input X4/RFR.
• C00142 = 8 (Enabled)
• In order to enable the device directly when switching it on, set bit 0 to zero (FALSE).
• An uncontrolled restart of the drive is possible.
