13.2.4. Absolute encoder connection for synchronous motors
ADrive supports absolute value encoders with EnDat, SSI and SinCos interface. The absolute
encoder connection for synchronous motors is made to ENCABIT-Plus module which is externally
mounted to the device for synchronous applications.
Technical specifications of absolute encoder inputs:
EnDat 2.1
SSI (*)
SinCos (*)
Encoder type is selected by the parameter
2.21.
● to 3-row 15-pole SUB-D female connector (for EnDat and SSI)
● to terminal strips (for EnDat, SSI and SinCos)
*: SSI and SinCos absolute value encoders are supported with firmware version >= 8.52.
For older versions, a firmware update must be performed.
13.2.4.1. Encoder connection with X-ENC1 connector (for EnDat and SSI encoders):
This connection method is suggested when the encoder connection cable has a ready-made 15-
pole SUB-D connector on driver side-end and the pin configuration of the SUB-D connector
corresponds to ENCABIT-Plus module. The pin assignment of X-ENC1 connector is shown in
the table below.
X-ENC1 connector can only be used for encoders with EnDat and SSI interface. SinCos encoder
connection must be made to the related terminals on ENCABIT-Plus.
*: It is recommended to connect the encoder wires 5V (Sensor)
and 0V (sensor) in parallel to terminals 5V (Up) and 0V (Un).

The metal casing of X-ENC1 socket is NOT earthed. Do
not use the socket casing for earthing purposes.
Refer to the statements given in 13.2.4.3 for encoder
connection.
