Encoder interface - X9

The SINAMICS V90 PN 200V variant servo drive supports two kinds of encoders:
● Incremental encoder TTL 2500 ppr
● Absolute encoder single-turn 21-bit
The SINAMICS V90 PN 400V variant servo drive supports two kinds of encoders:
● Incremental encoder TTL 2500 ppr
● Absolute encoder 20-bit + 12-bit multi-turn
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" in the SINAMICS V90, SIMOTICS S-
1FL6 Operating Instructions.
