Manual setting is only possible if the adaptive behaviour, parameter Adaptive
behaviour M0147, is switched off.
Customer settings M0041
Positioner M0145
Dead band OPEN M0234
Dead band CLOSE M0235
Default values: 0.5 % (for dead band OPEN and CLOSE)
Setting ranges: 0.0 % to 10.0 % (for dead band OPEN and CLOSE)
Information
●
Inner dead bands may not be set wider than outer dead bands.
●
Inner dead bands may not be set too narrow as this may cause unnecessary
switching procedures (premature wear) or oscillation of the actuator.
.
12.4.4. Set max. error variable (outer dead band) manually
The outer dead band determines the switching-on point of the actuator.
The motor starts if the actual value (input signal E2) or a change in setpoint is higher
than the maximum error variable determined by the outer dead band.
Manual setting is only possible if the adaptive behaviour, parameter Adaptive
behaviour M0147, is switched off.
Customer settings M0041
Positioner M0145
Outer dead band M0148
Default value: 1.0 %
Setting range: 0.1 – 10.0 %
12.4.5. Set the dead time
The dead time prevents the operation to a new setpoint position within a
pre-determined time.
Customer settings M0041
Positioner M0145
Dead time M0149
Default value: 3.0 s
Setting range: = 0.2 – 60.0 (seconds)
Information
Integral controls must ensure that the maximum permissible number of starts of the
actuator is not exceeded.This can be achieved by setting the dead time to a suffi-
ciently high value.
12.4.6. Set hysteresis for positioner
The hysteresis determines the switching accuracy. It can be used to reduce the
number of starts for example.
This setting can only be made if the adaptive behaviour, parameter Adaptive
behaviour M0147, is set to Adaptive I.
Customer settings M0041
Positioner M0145
Posit. hyst. OPEN M0598
Posit. hyst. CLOSE M0599
Default values: 0.5 % for OPEN and CLOSE
Setting range: 0.2 % to 5.0 % of travel (from OPEN to CLOSED)
