Functions / properties
Unit properties
•
Wide voltage range
– AC 400/500 V units for the voltage range 3
×
AC 380 ... 500 V
– AC 230 V units for the voltage range 3
×
AC 200 ... 240 V
•
High overload capacity
– 150 % I
N
, short-term
– 125 % I
N
, sustained operation without overload (pumps, fans)
•
With 4 kHz switching frequency, I
N
is permitted for an ambient temperature
ϑ
= 50 °C
•
4Q capability due to integrated brake chopper installed as standard
•
Compact unit design for minimum control cabinet space requirement and optimum
utilization of control cabinet volume
•
Integrated line filter fitted as standard in sizes 1 and 2, complies with class A limit on
the input side without any additional measures
•
6 isolated binary inputs and 3 binary outputs, one of which is a relay output, program-
mable inputs/outputs
•
1 TF/TH input for motor protection via PTC thermistor or thermocontact
•
3-color LED for displaying operating and error states
•
Separate DC 24 V voltage input for powering the inverter electronics (parameter set-
ting, diagnostics and data backup even when the supply system is switched off)
•
Removable connection unit and, with MOVIDRIVE
®
compact
MCH4_A, separable
electronics terminals
•
Separable power terminals for size 1 units
Control
functionality
•
VFC or CFC control modes for field-oriented operation (asynchronous servo)
•
With MCH4_A: Either asynchronous or synchronous AC motors can be operated
•
IPOS
plus®
positioning and sequence control system integrated as standard
•
2 complete parameter sets
•
Automatic motor calibration
•
Automatic brake control by the inverter
•
DC braking to decelerate the motor even in 1Q mode
•
Slip compensation for high static speed accuracy even without encoder feedback
•
Flying restart circuit for synchronizing the inverter to an already rotating motor
•
Hoist capability with all motor systems that can be connected
•
Motor pull-out protection through sliding current limitation in the field weakening
range
•
Function to hide speed window to avoid mechanical resonances
•
Heating current to avoid condensation build-up in the motor
•
Factory settings can be restored
•
Parameter lock for protection against changes to parameters
•
Speed controller and encoder input for types MCV (either sin/cos, TTL or HTL en-
coder), MCS (resolver) and MCH (either Hiperface, sin/cos or TTL encoder). Intuitive
controller setting tool in the user interface
