• In the case of rotary kit motors, the motor encoder can be connected
via a gear; Rexroth housing motors have a direct motor connection.
• The load side of the drive can be rotary or linear (S-0-0076).

encoder)
In the case of drives with rotary motor a rotary or linear load-side
(external) encoder can be necessary, depending on the application:
• A rotary external encoder can be connected to the load via an encoder
gear.
• A linear external encoder determines the actual position value directly
at the linear load.
