Encoder interface

The SINAMICS V90 200 V variant servo drive supports incremental encoder only, while the
SINAMICS V90 400 V variant servo drive supports incremental encoder and absolute
encoder.
NOTICE
Cable shielding
The encoder cable must be shielded to meet the EMC requirements.
NOTICE
Drive damage caused by short-circuiting between the shielding wire and the unused pin on
the encoder connector
The shielding wire may inadvertently be short-circuited to the unused pin on the to-be-
assembled encoder connector. This can cause damage to the drive.
Exercise caution when connecting the shielding cable to the encoder connector.
For more information, see section "Assembly of cable terminals on the drive side
(Page 337)".
