15.4.3 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 vari-
ous operating points should be avoided by an application-related parameterization. If
there is a fault switch-off, this report can be given via the parameter

15.4.5 Thermo contact

The monitoring of the motor temperature is a part of the error and warning behavior
which can be configured as required. The parameter

scribed in chapter "Motor Temperature". The temperature monitoring via a digital
input checks the input signal for the threshold value. Accordingly, a thermocontact or
an additional circuit must be used if a temperature-dependent resistor is used.

15.4.6 n-/M Control Change-Over

The field-orientated control procedures in configurations 230, 430, 530 and 630 con-
tain the functions for speed or torque-dependent control of the drive. The change-
over can be done in ongoing operation, as an additional functionality monitors the
transition between the two control systems. The speed controller or the torque con-
troller is active, depending on the
