2.1 Introduction
36 DC1 Variable Frequency Drive 04/16 MN04020003Z-EN www.eaton.com
An example for a magnet system
a Electrical supply system
(mains connection, grounding system
configuration, mains voltage, frequency,
voltage balance, THD, compensation
systems)
b Overall system – consisting of motor and
load systems
c PDS = Power drive system
d Safety and switching
(disconnecting devices, fuses, cable cross-
sectional areas, residual current circuit-
breakers, mains contactors)
e CDM = Complete drive module:
Variable frequency drive with auxiliary
equipment (mains and motor chokes, radio
interference suppression filter, brake
resistor, sine filter)
BDM = Basic drive module:
DC1 variable frequency drive
f Motor and sensor
(Temperature, motor speed)
g Load system:
Driven system equipment (process, speed,
torque)
