8.6 Connection of the control and communications signals
Motor feedback connection
The motor feedback device is an encoder.
It is connected directly through the feedback cable between the feedback
connector of the motor and connector X4 of the drive
as long as the isolation
level required by FAGOR is guaranteed between the motor temperature
sensor and the power circuit of the drive.
TSIA-1. Temperature sensor isolation adapter
For further detail on the cables supplied by FAGOR for connecting the motor
feedback, see chapter
7. CABLES . The technical data for the motor
feedback device connector is shown in the corresponding motor manual.
The pinout of the temperature sensor isolation adapter TSIA-1 is the same
as that of connector X4 of the drive's motor feedback. Refer to chapter
3.
DRIVES for how to connect the pins of connector X4 of the drive.
WARNING.
FAGOR uses isolation systems between the temperature
sensors and the winding of their motors ensuring long life to the motor-drive
system regardless of wiring lengths. When installing non-FAGOR motors,
since it cannot be guaranteed that the existing isolation will comply with
FAGOR standards, we recommend installing the isolation adapter TSIA-1.
See figure
F. H8/25 .
INFORMATION. Note that installing the temperature sensor isolation
adapter TSIA-1 means getting galvanic isolation between the temperature
sensor of the motor and the drive itself.

INFORMATION. Note that the isolation adapter TSIA-1 does not check the
encoder signals or the temperature sensor of the motor. It only provides
galvanic isolation of the temperature sensor.
