Note!
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 the Inverter Drives 8400 protec, the restart protection is
activated.
The restart behaviour of the controller can be set via C00142 ("Autostart
Option").
• C00142 = 9 (Lenze setting)
– The controller remains inhibited (even if the fault is not active anymore).
– Bit 0 (inhibit if device is ON) and bit 3 (inhibit in case of undervoltage) are
set.
– The drive starts in a controlled way thanks to explicit controller enable:
LOW-HIGH edge at a correspondingly configured digital input (connections
X41, X42, X43).
• C00142 = 8 (enabled)
– In order to enable the device directly when switching it on, set bit 0 to zero.
– An uncontrolled restart of the drive is possible.
