14.4.3 Error Acknowledgment

The frequency inverters feature various monitoring functions which can be adapted
via the error and warning behavior. Switching the frequency inverter off at the various
operating points should be avoided by an application-related parameterization. If
Pro-
there is a fault switch-off, this message can be acknowledged via the parameter
gram(ming) Error Acknowledg-
34 or the logic signal connected with the parameter
ment
103.

14.4.4 Timer

Operation Mode Timer 1
The time functions can be selected via the parameters

Operation Mode Timer 2
and 793. The sources of the logic signals are selected with
Timer 1 Timer 2
the parameters 83 and 84 and processed according to the config-
ured timer functions.

14.4.5 Thermo-contact

The monitoring of the motor temperature is a part of the error and warning behavior
Thermo contact
which can be configured as required. The parameter 204 links the
Motor Temp. Operation Mode
digital input signal to the defined 570 which is de-
scribed in chapter "Motor Temperature". The temperature monitoring via a digital
input checks the input signal for the threshold value. Accordingly, a thermo contact or
an additional circuit must be used if a temperature-dependent resistor is used.

14.4.6 n-/M-Control Change-Over

The field-orientated control procedures in configurations 230 and 430 contain the
functions for speed or torque-dependent control of the drive. The change-over can be
done during running operation of the drive, as an additional functionality monitors the
transition between the two control procedures. The speed controller or the torque
n-/M Control Change-Over
controller is active, depending on the
164.
