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
encoder inputs when
24V encoder
is selected in
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.

5-70 Term 32/33 Pulses per Revolution
Range:
Function:
1024
*
[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.
5-71 Term 32/33 Encoder Direction
Option:
Function:
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.
This parameter cannot be adjusted while the motor is
running.
3.7.8 5-9* Bus Controlled
This parameter group selects digital and relay outputs via a
fieldbus setting.
5-90 Digital & Relay Bus Control
Range:
Function:
0
*
[0 - 2147483647 ] This parameter holds the state of the
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.
