Operating Instructions ACU

16.4.3 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 there is a fault switch-off, this message can be
acknowledged via parameter Program 34 or the logic signal linked with parameter Error
Acknowledgment 103 .
16.4.4 Timer
The time functions can be selected via parameters Operation Mode Timer 1 790 and Operation
Mode Timer 2 793. The sources of the logic signals are selected via parameters Timer 1 83 and
Timer 2 84 and processed according to the configured timer function.
16.4.5 Thermocontact
The monitoring of the motor temperature is a part of the error and warning behavior which can be
configured as required. Parameter Therm. Contact 204 links the digital input signal to the defined
Motor Temp. Operation Mode 570, described in Chapter 14.6 "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.
16.4.6 n-/M control change-over
The field-oriented control procedures in configurations 230, 430, 530 and 630 contain 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 controller is active, depending on the n-/M-Control Change-Over
164.
16.4.7 Switch data set
Parameter values can be stored in four different data sets. This enables the use of various
parameter values depending on the current operation point of the frequency inverter. The change-
over between the four data sets is done via the logic signals assigned to parameters Data Set
Change-Over 1 70 and Data Set Change-Over 2 71.
The actual value parameter Active Data Set 249 shows the selected data set.

When Configuration 30 = 110, 111, 410, 411, 430, 510, 511, 530, 610, 611 or 630 is selected, a
timer function is connected by default between digital input S4IND and Data Set Change-Over 1.
