Installation instructions
SVM 4001K-A / 4001K-C
Standstill monitoring for 1- and 3-phases motor without sensor
system
Safety function during the adjustment
• The new parameters adjustment will be not memorized, if the power supply was turn-off during the adjustment or no actuation
of the SET button has happened longer than 20s.
• The old adjustment remains process active.
• The safety function and the faults monitoring are also active during the adjustment mode.
Faults monitoring
• During the function mode of SVM 4001K following external
and internal faults are monitored. LED b8 flashes red (pic-
ture 4) if:
− Wire breakage in the measurement circuit.
− Inconsistent signals at the single phases.
− Not allowed connection of the control inputs I11/I22
− Power supply out of the tolerance range
− Internal unit faults
• The faults monitoring is always active. (Inactive standstill
monitoring).
• The output contacts are open if there is a fault.

Standstill monitoring (Diagram 3b)
The standstill monitoring is inactive, if the control inputs I11 and
I22 are connected to 24 V DC via the safety cover switch and the
safety cover is closed. The output contacts are permanently
closed. The LED STOP illuminates green.
The standstill monitoring is active, if the safety cover is opened.
Function mode FA1 is selected. An emergency stop function will
be happened, if the drive moves.
