Positioning module IMD20, IMD40
Description of the drive module
Digital output Limit switch chain
The Limit Switch Chain output is designed as a potential-free contact. It indicates, if both limit
switches are not activated (closed potential-free contact). If one or both limit switch(es) is (are)
activated, the contact is open. In the safety circuit, this signal can be used to monitor the limit
switch.

Encoder connections
The drive module is preset for the connection of a quadrature incremental encoder with index signal.
The transfer of the signals is carried out according to the RS422 specification. It is recommended to
use shielded cables twisted in pairs for the encoder wiring.
The voltage supply of the encoder (5 volt) is provided by the rive module. The maximum supply
nt amounts to 100 mA.
