Unit
Frequency to which the switching frequency is
Hz reduced in case the frequency inverter is
overloaded.
The start command entered via the control unit
or digital inputs S2IND, S3IND results in an
Hz
acceleration of the drive to the minimum
frequency.
The speed range of the drive is limited by the
Hz maximum output frequency of the frequency
inverter.
The ramps define how quickly the output
Hz/s frequency is changed if the reference value
changes or after a start, stop or brake command.
The reference value at input MFI1 can be
- adjusted in this operation mode according to the
connected signal source.
Switching between the fixed frequency values is
done via the fixed frequency change-over of
multifunction input MFI1 (

Hz
data record change-over S4IND, S5IND, the fixed
frequency in one of the four data records can be
selected. Up to 8 fixed frequencies can be
parameterized and selected via the control of the
digital inputs.
Various control and monitoring functions can be
- assigned to digital output S1OUT and relay
output S3OUT.
Output MFO1 supplies a pulse width modulated
- signal (0 V ... 10 V) which is proportional to an
actual value.
Monitoring the motor temperature protects the
- drive system. Connect a suitable sensor to digital
input S6IND.
Motor circuit breakers are used for protecting a
motor and its supply cable against overheating
by overload. Depending on the overload level,
- they disconnect the motor from power supply
immediately in the case of a short-circuit or they
disconnect the motor if an overload has occurred
for some time.
