Parameter Descriptions
3.7.7 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 24 V encoder is selected in par. 1-02 Flux Motor
Feedback Source and par. 7-00 Speed PID Feedback Source. The
encoder used is a dual channel (A and B) 24 V type. Max input
frequency: 110 kHz.
Encoder Connection to the frequency converter
24 V incremental encoder. Max. cable length 5 m.

Function:
[1 - 4096 ] Set the encoder pulses per revolution on the
*
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.
Clockwise Sets channel A 90° (electrical degrees)
*
behind channel B upon clockwise rotation of
the encoder shaft.
Counter Sets channel A 90° (electrical degrees) ahead
clockwise of channel B upon clockwise rotation of the
encoder shaft.
