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
impermissible for the drive to restart.
In the Lenze setting of Servo Drives 9400, the restart protection is activated.
The restart behaviour of the inverter can be set via
C00142
("auto restart after mains
connection"):
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• The inverter remains inhibited (even if the fault is no longer active).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.
