Parameter is active in configurations with field-oriented control (FOC), e.g. 210, 410.

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 (

452 to setting 3). Via the data set change-over
Hz
S4IND, S5IND, the fixed frequency in one of the four
data records can be selected. Up to 8 fixed frequen-
cies can be parameterized and selected via the con-
trol of the digital inputs.
Various control and monitoring functions can be as-
- signed to digital output S1OUT and relay output
S3OUT.
Output MFO1 supplies a pulse width modulated sig-
- nal (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.
Synchronization to a rotating drive is useful in some
applications such as pumps and fans or after ac-
- knowledgment of an error switch-off.
If synchronization to the motor speed is not possible,
the function is quit and a fault message is issued.
Automatic startup of the drive is permissible only in
accordance with VDE 0113 (Section 5.4, 5.5), VDE
- 0100 Part 227 and the national regulations. Make
sure that automatic startup does not result in any
dangerous situation.
The DC link voltage, which increases due to genera-
toric operation and/or deceleration operations, is lim-
- ited by means of the voltage controller or an external
braking resistor in order to avoid an error switch-off
due to overvoltage.
The control behavior of configuration 410 is to be
adapted, depending on the mechanical moment of
inertia, via the integral time of the speed controller.
ms The smaller the value is, the more dynamic the be-
havior. The increase in inherent instability of the sys-
tem is proportional to the reduction of the integral
time.
The speed and torque can be controlled separately in
configuration 410. The torque is limited to the rated
A
torque if the current limit is the same as the Rated
current 371 of the motor.
