TTL Incremental Terminal Strip - Encoder Connections
3.3.1 Incremental TTL
Encoder Interface X3A

Screw Terminals

i
Connect the incremental encoder mounted on the motor to the 8-posi-
tion terminal connector at X3A. This connection provides speed feed-
back and is imperative to the proper operation of the F5.
ONLY when the inverter is switched off and the volt-

age supply is disconnected may the feedback con-
nectors be removed or connected!

*If the encoder has no zero channel, connect N+ (X3A.5) to 5V (X3B.7) and
N- (X3A.6) to 0V common (X3A.8 or X3B.8) to avoid 'Error Encoder1' faults.
**For 5V supply TTL encoders, a 5V supply is available on the second inter-
face channel, X3B.7.
