6 Inputs and outputs
Positioner DC 6-06 37
6.5 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.
Output Use Name Terminal Specification
PWM output 2
*
Current actuator value P2 1, 3
0.3 A
low side
50…500 Hz
*
optional analogue output
Table 13: PWM output
6.5.1 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 m
ust 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.
6.6 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.
Output Use Name Terminal Specification
Error output Common alarm Err 10, 21
0.3 A
low side
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.
