7.3.10 Suppressing interference of the system
Should interference occur in conjunction with signals of the VT-HMC...1X, inspect
the interference suppression of other electrical components, e.g. as follows:
Possible causes of faults
Switched inductance
Electric motors
Frequency converter

BASIC PRINCIPLES
Uncontrolled plugging and unplugging of connectors!
The device might be destroyed. Damage to the control system caused by incorrect
installation is not covered by the warranty!
▶ Before carrying out any installation work or plugging or unplugging connectors
from the product, disconnect the device from the power supply or the voltage
source or de-energize it reliably.
▶ Observe the protection class, the voltage supply and the environmental
conditions according to data sheet 30239.
A prerequisite for the function of the VT-HMC...1X is its parameterization
and programming (→ creation of the PLC application) using the software
IndraWorks Ds or IndraWorks MLD.
• IndraWorks Ds can be used only for parameterization and diagnostics.
• IndraWorks MLD is required, if the PLC functionality according to IEC 61131-3 is
to be used additionally.
For operation, the VT-HMC...1X must be ready for operation, connected to the PC
via the Ethernet interface (XF20 or XF21) and be online.
DC: antiparallel free-wheeling diode over actuator winding
AC: type-related R/C combination over actuator winding.
R/C combination from each motor winding to earth.
Inlet filter in the voltage supply of the frequency converter
Motor control lines shielded and installed separately from other
cables and/or output filter for motor cables.
Large-area contact of the frequency converter housing to the
rear wall of the control cabinet
