Motor Setup
9.12.1
Setting motor rated current
MotorRatedCurr.
MotorRatedCurr.
Possible setting for the motor rated current.
The setting for the
“
DC brake level
”
(
setting brake behaviour) refers to this setting.
Setting range: 0.0...device rated current / A
Factory setting: device rated current
9.12.2
Setting motor rated voltage
MotorRatedVolt.
MotorRatedVolt.
When commissioning, you must set the motor to the rated voltage stated on the rating
plate.
Caution! Make settings for U/f curve and motor rated voltage only while the motor is not
being triggered.
Verify the output voltage using suitable measuring instruments.
Adjustment range: 0...270 V (settings above 270 V do not yield a higher output voltage)
Factory setting: 230 V
9.12.3
Adjustment of the U/f curve
Information
The device comes supplied with a preprogrammed square characteristic curve for the operation of
fans.
In the case of voltage-controllable motors and square load torque-moments (e.g. fans and pump
operation), an optimal speed control is generally achieved through this.
In systems in which high dynamics are required, switchover to a linear characteristic must take place.
Generally speaking, if the load characteristic is not known as a de
fi
nite value, the linear characteristic
should be set. In the case of linear characteristic curves, the motor achieves full torque throughout the
entire speed range. For this, a thermal overload of the motor must be prevented through suitable
measures (complete motor protection through using thermocontact or PTC thermistor-monitoring).
Edgefrequency
Edgefrequency
The maximum output voltage is attained during break edge frequency.
Adjustment range: 10.0 - 150.0 Hz
Factory setting: 50.0 Hz
Max. Frequency
Max. Frequency
Above the Edgefrequency, the frequency is merely increased up to the Maximum
frequency.
Adjustment range: 10.0 - 150.0 Hz
Factory setting: 50.0 Hz
