Actuator position output with PWM output
The current actuator value can be output as a PWM signal on the port at Pin 1 and 3
when 4335
ActPosOutPWMOrAnalog
= 1 is set.

Value range of the PWM output
Normally only a PWM ratio of between 5 and 95 % is desired.
Parameters 1601
PWMOut_RefLow
and 1602
PWMOut_RefHigh
must be used to match
the output range. The limits are entered directly in percent PWM ratio.
The frequency of the PWM signals can be set with parameter 1625
PWMOutFrequency
.

Common alarm via alarm output
The port on Pin 10 to which the signal 3801
CommonAlarm
is automatically assigned is
used for error display. This common alarm is always active when at least one error is
present in the system. The output can be used for an optical or an acoustic signal.

Table 14: Alarm output
The common alarm can be configured high or low active depending on how 5000
CommonAlarmLowActive
is set.
5000
CommonAlarmLowActive
= 0
Output = 1 when at least one error is
present, otherwise 0
5000
CommonAlarmLowActive
= 1
Output = 0 when at least one error is
present, otherwise 1
In order to tell a higher-level system that a new error has occurred, 5102
CommonAlarmResetOn
= 1 is set. Consequently with each new error the active common
alarm output is reset for 500 ms.
