Configuring the analogue inputs and outputs 

The  analogue  input  (external  setpoint  input)  as  well  as  the  analogue  output 

(position feedback) are usually set to 4-20 mA as standard. 

 

 

00-10 only: 

The  analogue  input  and  the  analogue  output  can  be  used  either  in  4-20  mA  or  

0-20 mA operation.  

 

00-15 and 01-15 only: 

The analogue input and the analogue output can be used in current or voltage mode 

(0/4-20 mA or 0/2-10 V). 

DIP switch S15

 on the base board must be set accordingly. 

This DIP switch is used to switch the mode for position feedback between voltage and 

current.  

 1: ON, 2: OFF; current (mA) 

 1: OFF, 2: ON; voltage (V) 

 

The  desired  operating mode of the  analogue interface  must be stored  in  the  device 

settings in line with the instructions under menu item 

Mode 1: Setting the analogue 

signal 

in the section 

Configuration mode

 1. The operating mode is set jointly for input 

and output.  

Calibration of the analogue inputs and outputs 

The  analogue  input and the  analogue  output of the  drive are  calibrated at the 

factory.

 Recalibrating the analogue interface is usually only necessary if there are very 

high requirements for angular accuracy or, for example, if the connection cables are 

long.  The  calibration  procedure  is  described  in  the  section 

Configuration  mode

  2

 

under the menu items 

Mode 2, Mode 3, and Mode 4
