Danfoss Electronics MCD 500 Features and Benefits
VLT® Soft Starter MCD 500
VLT® Soft Starter MCD 500 is a total motor starting solution. Current transformers measure motor current
and provide feedback for controlled motor ramp proles.
AAC, Adaptive Acceleration Control,
automatically employs the best
starting and stopping prole for the
application.
Adaptive Acceleration Control means
that for each start and stop, the soft
Perfect
match for:
– Pumps
– Conveyors
– Fans
– Mixers
– Compressors
– Centrifuges
– Mills
– Saws, and many more
starter compares and adapts the
process to the chosen prole tting to
the application.
Three menu systems: Quick Menu,
Application Setup and Main Menu
provide optimum programming
approach.
VLT® Soft Starter MCD 500 has a four
line graphical display and a logic
keypad making programming easy.
Advanced setup is possible displaying
operational status.
Power range:
21 – 1600 A, 10 – 1140 HP
(1600 HP inside Delta Connection)
Versions for 200 – 690 VAC
Feature Benet
AAC Adaptive Acceleration Control
Adjustable bus bars allow for both top and
bottom entry (360–1600 A, 160–850 kW)
DC injection braking distributed evenly
over three phases
Inside Delta (6-wire connection)
Log menus, 99 events and trip log provide
information on events, trips and performance
Auto Reset – Less down-time
Jog (slow-speed operation) – Application exibility
Second-order thermal model
Internal bypass contactors
(21–215 A, 7.5–110 kW)
Auto-start/stop clock – Application exibility
Compact size – amongst the smallest
in their class

Three Adapt ive Acceleration Control (AAC) star t proles;
early, constant and late acceleration
Time
– Automatically adapts to the chosen
starting and stopping prole
– Space saving, less cable cost
and easy retrotting
– Less installation cost and
less stress on the motor
– Smaller soft starter can be selected
for the application
– Eases analysis of the application
– Allows motors to be used to their full
potential without damage from overloading
– Saves space and wiring compared to
external bypass
– Very little heat dissipates when running.
Eliminates costly external fans, wiring
or bypass contactors
– Saves space in cabinets and other application
setups
– Optimum programming approach and setup
for viewing operational status
– Simplies the programming, but still holding
to maximum exibility
