Parameter Descriptions
3.7.7 5-7* 24 V Encoder Input
Connect the 24 V encoder to terminal 12 (24V DC supply),
terminal 32 (Channel A), terminal 33 (Channel B), and
terminal 20 (GND). The digital inputs 32/33 are active for
3 3 encoder inputs when 24V encoder is selected in 1-02 Flux
Motor Feedback Source and 7-00 Speed PID Feedback Source.
The encoder used is a dual channel (A and B) 24V type. Max
input frequency: 110kHz.
Encoder Connection to the frequency converter
24V incremental encoder. Max. cable length 5m.

Function:
motor shaft. Read the correct value from the
encoder.
This parameter cannot be adjusted while the
motor is running.
Function:
Change the detected encoder rotation
direction without changing the wiring to the
encoder.
Sets channel A 90° (electrical degrees)
behind channel B upon clockwise rotation of
the encoder shaft.
Sets channel A 90° (electrical degrees) ahead
of channel B upon clockwise rotation of the
encoder shaft.
Function:
digital outputs and relays that is controlled
by bus.
A logical '1' indicates that the output is
high or active.
A logical '0' indicates that the output is
low or inactive.
