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 device
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:

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 incompatible.

X4 connector. 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 model
is a B. If not, it will have a CAPMOTOR-1.
The feedback of FAGOR motors use sinusoidal encoder, incremental TTL
encoder or resolver. Refer to the corresponding motor manual for the
detailed 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. See
figures F. H3/64, F. H3/65, F. H3/66, F. H3/67 and F. H3/68.
