KCM-E Expansion module for both applications. Expansion modules are available in
The KCM modules can be connected to S7010 ... S7240 devices (mains supply voltage
400/480V, rated current max. 24A). Information for mounting, installation and setup can
be found in the KCM Instructions Manual.

Remove the plug-in link between the terminals X8/4 (-RB) and
X8/3 (+Rbi). Fuse types see p. 30. Information for brake circuit
and technical data can be found on page 33. Use the optional
Y-connector X8Y (set with X4Amini for better assembly, see
order numbers on p.161), if you want to link the DC bus with

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