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– The controller remains inhibited (even when the fault is no longer active).
– Bit 0 (inhibit at power-on) and bit 3 (inhibit in the case of undervoltage) are
set.
– The drive starts in a controlled mode by an explicit controller enable: LOW-
HIGH edge on a digital input configured correspondingly (terminals 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.
