Positioning module IMD20, IMD40
Description of the drive module
Enc
ended to
se shielded cables twisted in pairs for the encoder wiring.
he voltage supply of the encoder (5 volt) is provided by the drive module. The maximum supply
current amounts to 100 mA.
oder 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 recomm
