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.
Activating changed setting
In order to activate any changed settings, ...
• execute the device command "11: Save start parameter" via the standard device code
C00002 and ...
• then reset the bus node or switch off and on again the voltage supply of the
communication module.
Protection against uncontrolled restart
After a fault (e.g. short-term mains failure), it is sometimes undesirable or even
impermissible for the drive to restart.
In the Lenze setting of Servo Drives 9400, the restart protection is activated.
Via the standard device code C00142 ("Auto restart after mains connection") you can set
the restart behaviour of the inverter:
C00142 = "0: Inhibited" (Lenze setting)
• The inverter remains inhibited (even if the fault is no longer active).
• An explicit controller enable causes the drive to start up in a controlled manner: LOW-
HIGH edge at digital input X5/RFR.
C00142 = "1: Enabled"
• An uncontrolled restart of the drive is possible.
