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
9.13.2
Setting motor rated voltage
MotorRatedVolt.
MotorRatedVolt.
When commissioning, you must set the motor to the rated voltage stated on the
rating plate.
An adaptation can be made if the motor rated-voltage as the applied mains voltage is
lower (e.g. 3 ~ 230 V motor on 3 ~ 400 V mains).
Verify the output voltage using suitable measuring instruments.
Setting range: 0...500 V
Factory setting: 400 V
9.13.3
Adjustment of the U/f curve
Information
The device comes supplied with a preprogrammed square characteristic curve for the oper-
ation 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: 1.0 - 120.0 Hz
Factory setting: 48.5 Hz
In the case of special settings with
