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 power on/off state of the
standard device is irrelevant.
Activating altered settings
To activate altered settings, ...
• use standard device code C00002 to execute the device command "11: save
all parameter sets", and ...
• then switch the voltage supply of the communication module off and on
again.
Protection against uncontrolled restart
Following a fault (e.g. short-term mains failure), it is sometimes undesirable or
even impermissible for the drive to restart.
In the Lenze setting for Inverter Drives 8400, restart protection is active.
The restart behaviour of the controller can be set using C00142 ("autostart
option"):
• C00142 = 9 (Lenze setting)
– The controller remains inhibited (even when the fault is no longer active).
– Bit 0 (inhibit at power-on) and bit 3 (inhibit in the case of undervoltage) are
set.
– An explicit controller 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.
