3.4.2 Stop via multi-function inputs
Multi-function inputs offer additional possibilities to survey the motor and the production process it is
used for. Via the parameters DI0 Multi-function input, DI1 Multi-function input and DI2 Multi-function input
the inputs DI0, DI1 and DI2 can be parameterized as multi-function inputs with the following functions:
Transparent (default): status is monitored only to the fi eldbus
Fault signal always / not delayed or delayed with 1 to 255 s:
The delay time starts whether the motor is running or not.
Fault signal dependent / delayed with 1 to 255 s:
The delay time starts only when the motor is running.
Motor off always / not delayed or delayed with 1 to 255 s:
The delay time starts whether the motor is running or not.
Motor off dependent / delayed with 1 to 255 s:
The delay time starts only when the motor is running.
Reset internal fault signal
Prepare emergency start: Reset of the thermal memory and of other faults.
Test allows to start without motor (no current check-back when started)
Application example for "Fault signal dependent / delayed"
Chapter 3.4.2~1
Pressure switch
2CDC 342 039 F0206
Situation: When the motor is starting there is no pressure. It takes some time until the pressure
reaches the threshold value. The pressure has to appear within e.g. 4 seconds, other-
wise the pump can be destroyed Fault.
Solution: Set e.g. DI0 Multi-function input = P032 (Fault signal dependent / delayed)
with a delay
time of 4 s):
If the pressure switch does not monitor "pressure present" within 4 s (or when the pres-
sure signal disappears for more than 4 s during operation) the internal fault signal is set
and the motor is stoped.
Remark: The pressure signal is a closed-circuit signal: "pressure present" = closed contact.
