Initial switch-on

Documentation for the standard device
Observe the safety instructions and residual hazards stated.

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.
Activating changed settings
In order to activate changed settings ...

• execute the device command "11: Save all parameter sets" via the standard device

code C00002 and ...

• then execute a "reset node" of the node or switch off the voltage supply of the

communication module and switch it on again.

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 for Inverter Drives 8400, the restart protection is active.
Via the standard device code C00142 ("Autostart option") you can set the restart

behaviour of the inverter:
C00142 = 9 (Lenze setting)

• The inverter remains inhibited (even if the fault is no longer active).
• Bit 0 (inhibit if device is ON) and bit 3 (inhibit in case of undervoltage) are set.
• An explicit inverter enable causes the drive to start up in a controlled manner: LOW-

HIGH edge at digital input X4/RFR.

C00142 = 8 (enabled)

• In order to directly enable the device at switch-on, bit 0 must be set to zero (FALSE).
• An uncontrolled restart of the drive is possible.
