AUMA ACVExC 01.2 Series User Manual

8.5.9. Speed reduction before reaching setpoint position
Characteristics
The function adapts the setpoint depending on the error variable compared to the
setpoint. In case of a low error variable compared to the setpoint, the actuator runs
at low speed. For a high error variable, the actuator runs at maximum speed. The
maximum speed is then equal to the current speed.
Application
For modulating duty with high positioning accuracy.
Activate speed reduction before reaching setpoint position
Required user level: Specialist (4) or higher.
Customer settings M0041
Positioner M0145
Speed red.before setp. M0835
Default value: Function active
Setting values:
Function not active
<Speed reduction> function deactivated.
Function active
<Speed reduction> function activated.
Set speed reduction range
Range in relation to the setpoint, where the speed – depending on the deviation from
the setpoint – is either reduced or increased from the current speed to the "target
speed" (parameter Target speed at setp. M1939).
Customer settings M0041
Positioner M0145
Speed red. range M0836
Default value: 10.0 %
Setting range: 2.0 – 20.0 (deviation from the setpoint in %)
Set target speed before reaching setpoint position
Minimum speed for modulating duty.

Default values: 10 rpm
Setting range: 6 ... 240 rpm
The adjustable speed range is indicated on the actuator name plate.
8.5.10. Change-over between OPEN - CLOSE control and setpoint control
For actuators equipped with a positioner, it is possible to change over between OPEN
- CLOSE control (Remote OPEN-CLOSE) and setpoint control (Remote
SETPOINT).
Condition
For the change-over, a digital input for the signal MODE has to be available and
configured.
Configuration of digital input
Required user level: Specialist (4).
Device configuration M0053
I/O interface M0139
Digital inputs M0116
Example
Use input DIN 1 for change-over:
Parameter: Signal DIN 1 M0118
