9.9.3 Capacitor Module KCM (X8)

KCM-S Saves energy: The energy stored in the capacitor module during regenerative brak-
KCM-P Power in spite of power failure: If the power supply fails, the module provides the
KCM-E Expansion module for both applications. Expansion modules are available in two
The KCM modules can be connected to S7010 ... S7480 devices (mains supply voltage
400/480V). Information for mounting, installation and setup can be found in the KCM Instruc-
tions Manual and in KDN.

There is a danger of serious personal injury or death by electrical shock or electrical arcing. It
can take over an hour for the modules to self-discharge.

The KCM modules (KOLLMORGEN Capacitor Module) absorb energy gen-
erated by the motor when it is operating in generator mode. Normally, this
energy is dissipated as waste via brake resistors. KCM modules, however,
feed the energy they have stored back into the DC Bus link as and when it
is required.

High DC voltage up to 900 V!
Switch off (disconnect) the line voltage. You must only work on the connections when
the system is disconnected.
Check the state of charge with a measuring device that is suitable for a DC voltage of up
to 1,000 V.
When measuring a voltage of over 50V between the DC+/DC- terminals or to ground,
wait some minutes and measure again or discharge the modules as described in the
KCM instructions manual.
