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:
Encoder interface type EnDat 2.1
SSI (*)
SinCos (*)
Encoder type is selected by the parameter
2.21.
Encoder resolution 2048 pulse/revolution
Encoder supply voltage 5Vdc ± %5
Max. supply current 400mA
Connection type ● 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).

not use the socket casing for earthing purposes.
Refer to the statements given in 13.2.4.3 for encoder
connection.
