5.2.5 Function of a servomotor with analogue
control
The microprocessor controller is integrated in the
drive housing. The controller positions the drive
based on a guide value (setpoint in mA signal) and
compares the specified setpoint with the actual drive
position (actual value). If the two values differ, the
drive is moved to the position determined by the
setpoint. The actual value is generated by a
potentiometer integrated in the drive.
Any positions can be assigned to 4 (0) mA and 20
mA at any time. The lower and upper current limits (4
(0)/20 mA) are pre-programmed and cannot be
changed. The control direction can also be reversed
using a DIP switch " /inv".
5.2.6 Function of a spare servomotor with
reversing potentiometer
The drive is positioned at the relevant terminals
(motor control open/closed) for the corresponding
direction of rotation by switching the supply voltage
on/off. The reversing potentiometer returns the
current position of the servomotor to the controller;
the position is held when the setpoint is reached.
Observe the supplier manual for the servomotor
provided with the product.
