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

Switching between the fixed frequency values is done via the
fixed frequency change-over of multifunction input MFI1

the data record change-over S4IND, S5IND, the fixed fre-
quency 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 breakersare 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 dis-
connect the motor if an overload has occurred for some time.
Motor protection, in particular self-ventilation motors, is im-
% proved via the
percentage of the rated frequency.
Synchronization to a rotating drive is useful in some applica-
tions such as pumps and fans or after acknowledgment 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 ac-
cordance 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 generatoric ope-
ration and/or deceleration operations, is limited 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 integ-
ral time of the speed controller. The smaller the value is, the
ms
more dynamic the behavior. The increase in inherent instabili-
ty of the system is proportional to the reduction of the integ-
ral time.
The speed and torque can be controlled separately in configu-
ration 410. The torque is limited to the rated torque if the
A
current limit is the same as the Rated current 371 of the mo-
tor.
