Note: For 5V TTL encoders, a 5V supply is available on second interface,
X3B terminal 7.
If an incremental encoder does not have N+/N- tracks then the
corresponding inputs on the encoder interface card must be
jumpered high/low or the drive will trigger the error, E.ENC1. For
example, connect N+ (X3A.5 ) to 5V (X3B.7) and N- (X3A.6) to 0V
(X3A.8).

In Screw Terminals
Connect the incremental encoder mounted on the motor to the 8 position
terminal connector at X3A. This connection provides speed feedback
and is imperative to the proper operation of the F5M.
ONLY when the inverter is switched off and the voltage
supply is disconnected may the feedback connectors
be removed or connected!
The following speci cations apply to encoder interface X3A, channel 1
• Max. operating frequency: 300 kHz.
• Maximum cable length: 50m (164 ft) (RS422)
• Internal terminating resistance: R
t
= 120
• RS422 or TTL level square wave
voltage level: 2...5 Vdc
