AUMA ACVExC 01.2 Series User Manual

Customer settings M0041
Positioner M0145
Dead band OPEN M0234
Dead band CLOSE M0235
Default values: 0.5 % for dead band OPEN and CLOSED
Setting ranges: 0.0 – 10.0 % for dead band OPEN and CLOSED
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.
.
8.5.4. Max. error variable (outer dead band): set 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 nominal value is
higher than the max. error variable determined by the outer dead band.
Manual setting is only possible if the adaptive behaviour, parameter Adaptive
behaviour M0147 switched off.
Customer settings M0041
Positioner M0145
Outer dead band M0148
Default value: 1.0 %
Setting range: 0.1 – 10.0 %
8.5.5. Dead time: set
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: 0.5 s
Setting range: 0.2 – 60.0 s (seconds)
Information
It must be ensured via the controls that the max. 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.
8.5.6. Hysteresis for positioner: set
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 M041
Positioner M0145
Posit. hyst. OPEN M0598
Posit. hyst. CLOSE M0599
Default values: 0.5 % for OPEN and CLOSED
Setting range:0.0 % to 5.0 % of the travel (from OPEN to CLOSED)
8.5.7. Closing fully/opening fully (end position tolerance for setpoint)
If the end positions cannot be reached due to inaccurate analogue setpoint signals
(0/4 mA or 20 mA), a tolerance for the setpoint within the end position range can be
set. If the tolerance is exceeded or not reached, the actuator continues the operation
