4.6.5 5-7* 24 V Encoder Input
Connect the 24 V encoder to terminal 12 (24 V DC supply),
terminal 32 (channel A), terminal 33 (channel B), and
terminal 20 (GND). The digital inputs 32/33 are active for
encoder inputs when
[1] 24 V encoder
is selected in
parameter 7-00 Speed PID Feedback Source
. The encoder
used is a dual-channel (A and B) 24 V type. Maximum
input frequency: 110 kHz.
Encoder connection to the frequency converter
24 V incremental encoder. Maximum cable length is 5 m
(16.4 ft).

*
[1 - 4096]
Set the encoder pulses per
revolution on the motor shaft. Read
the correct value from the encoder.
5-71 Term 32/33 Encoder Direction
Option:
Function:
NOTICE
This parameter cannot be
adjusted while the motor is
running.
Change the detected encoder
rotation direction without changing
the wiring to the encoder.
[0]
*
Clockwise
Sets channel A 90° (electrical
degrees) behind channel B upon
clockwise rotation of the encoder
shaft.
[1]
Counter
clockwise
Sets channel A 90° (electrical
degrees) ahead of channel B upon
clockwise rotation of the encoder
shaft.
