Functions / features
MOVITRAC
®
07 frequency inverters are characterized by the following attributes:
Unit properties
•
Wide voltage range:
– 230 V units 1-phase and 3-phase for the voltage range 200 ... 240 V
AC
, 50/60 Hz
– 400/500 V units for the voltage range 3 x 380 ... 500 V
AC
, 50/60 Hz
•
Overload capacity: 150 % I
N
for maximum 60 s
125 % I
N
continuous power (fan/pump operation)
Maximum 180 % breakaway torque
•
Rated operation (I
N
= 100 %) up to ambient temperature
ϑ
= 50 °C.
•
4-quadrant capability due to the integrated brake chopper.
•
Compact unit mounting position for minimum switch cabinet space requirement and
optimum utilization of switch cabinet volume.
•
Integrated EMC line filter to EN 55011 for compliance with limit value class:
– Class B: 1-phase connection
– Class A: 3-phase connection
– 230 V: 0.37 ... 7.5 kW
– 400/500 V: 0,55 ... 11 kW
•
Inputs and outputs programmable
– 1 analog input
– 5 binary inputs
– 2 binary outputs, 1 of which is a relay output
•
Integrated voltage supply and evaluation for TF (PTC temperature sensor) for tem-
perature monitoring of the motor.
•
Integrated operating panel for displaying setpoints and setting parameters
– 10 LEDs for displaying the selected symbols
– 5 operation buttons
– 1 setpoint potentiometer for specifying the speed
•
Braking resistor can be integrated as an option in sizes 0S, 0M and 0L.
Control functions
•
VFC control mode or V/f control.
•
Automatic brake control by the inverter.
•
DC braking to decelerate the motor even in 1-quadrant mode.
•
Slip compensation for high static speed accuracy.
•
Motor pull-out protection by sliding current limitation in the field weakening range.
•
Factory settings can be reactivated.
•
Parameter lock to protect against parameter changes.
