8.9.2 Capacitor Modules (X3)
KCM modules (KOLLMORGEN Capacitor Modules) absorb kinetic
energy generated by the motor when it is operating in generator mode.
Normally, this energy is dissipated as waste via regen resistors. KCM
modules, however, feed the energy they have stored back into the DC
Bus link as and when it is required.
Assembly information: see regional accessories manual or KCM instruc-
tion manual.
Dimensions (HxWxD) : 300x100x201 mm
KCM-S Saves energy: The energy stored in the capacitor module during generative brak-
ing is available the next time acceleration happens. The module’s inception volt-
age is calculated automatically during the first load cycles.
KCM-P Power in spite of power failure: If the power supply fails, the module provides the
servo amplifier with the stored energy that is required to bring the drive to a stand-
still in a controlled manner (this only applies to the power supply voltage;
battery-back the 24 V supply separately).
KCM-E Expansion module for both applications. Expansion modules are available in two
capacitance classes. The modules can be combined as required.
The KCM modules may only be connected to AKD with 400/480 V rated voltage and a max-
imum rated current of 24 A. Mounting, installation, and setup instructions can be found in the
Instructions Manual of the KCM Modules.
DC Bus link terminals in servo systems carry high DC voltage of up to
900 V. Touching the terminals while they are carrying voltage is
extremely dangerous. Switch off (disconnect) the line voltage. You must
only work on the connections when the system is disconnected.
It can take over an hour for the modules to self-discharge. 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 40 V between the
DC+/DC- terminals or to ground, discharge the modules (see "Dis-
charging KCM modules" (➜ p. 99)).
