Note!
Establishing communication
In order to establish communication via an externally supplied communication module,
the standard device must be switched on as well.
After communication has been established, the externally supplied module operates
independently of the power on/off state of the standard device.
Protection against uncontrolled restart
After a fault (e.g. short-time mains failure), the restart of a drive is not always wanted
and - in some cases - even not allowed.
In the Lenze setting of the Inverter Drives 8400, the restart protection is activated.
The restart behaviour of the inverter can be set via C00142 ("Autostart Option"):
C00142 = 9 (Lenze setting)
• The inverter remains inhibited (even if the fault is no longer active).
• Bit 0 (inhibited at power-on) and bit 3 (inhibited at undervoltage) are set.
• The drive starts in a controlled mode by explicitly enabling the inverter: LOW-HIGH
edge at digital input X4/RFR.
C00142 = 8 (enabled)
• To enable the device directly at power-on, bit 0 must be set to zero (FALSE).
• An uncontrolled restart of the drive is possible.
