X4 connector
X4. Motor feedback
Is the connector for the motor feedback board that may come on modular
drives. It is a high density (HD) 26-pin sub-D type female connector.
Through it, the board receives the signals coming from the feedback de-
vice attached to the motor shaft.
The pinout of connector X4 depending on whether the motor feedback
board installed at the drive is a CAPMOTOR-1 or a CAPMOTOR-2 is:
The feedback of FAGOR motors use sinusoidal encoder, incremental TTL
encoder or resolver. Refer to the corresponding motor manual for the de-
tailed description of the pinout of the feedback devices that can go with
each motor family.
With CAPMOTOR-2, this connector admits signals:
 Square TTL
 1 Volt peak-to-peak sinusoidal (1 Vpp)
 SSI
 EnDat
with the following working frequencies:
 1 MHz with square signals
 500 kHz with sinusoidal signals
The input impedance for sinusoidal signals is 120

The characteristics of the signals are the same as the ones described in
the previous chapter for the incremental and absolute feedback devices.

Connector X4. Feedback on the motor. CAPMOTOR-1 or CAPMOTOR-2.
NOTE. To know whether your drive has a CAPMOTOR-2 installed,
check the label on the side of the drive and see if the last field of the
sales reference is a B. If not, it will have a CAPMOTOR-1.

Notes.
Do not select a drive with CAPMOTOR-2 when the motor feedback is
a resolver. They are incompatible. In this case, the drive must always
carry a CAPMOTOR-1.
Do not connect an SSI or EnDat feedback device to connector X4 of
the drive of a CAPMOTOR-1 motor feedback board. They are incom-
patible.
