8 Important Circuit Information
8.16 VPM Voltage Protection Module
Signal contact X3
!
!
8-330
When the VPM is tripped or in the event of a temperature fault, signaling contact
X3 opens and interrupts the pulse enable of the SIMODRIVE converter
(see Fig. 8-45).
Warning
The signaling contact X3 closes autonomously after t > 2 min or after the
temperature switch has been reset. Therefore, measures must be adopted to
prevent the drive from starting by itself!

Caution
When a VPM is tripped, the short–circuit thyristor must be safely cleared before
the connected drive can be switched on again. This is only ensured if the motor
has first come to a standstill.
An X3 signal contact that has closed again is not an explicit indication that
this has occurred.
Be especially cautious of this in the event of servicing.
