5-70 Term 32/33 Pulses Per Revolution
Range: Function:
1024 [1 - 32768] 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 Sets channel A 90° (electrical degrees) ahead
clockwise of channel B upon clockwise rotation of the
encoder shaft.
5-72 Term 32/33 Encoder Type
Select the signal type of the encoder connected to terminals 32,
33.
Option: Function:
[0] Quadrature A/B Encoder with 2 tracks: A and B,
*
Format displaced 90° for detecting the
rotational direction.
[1] Single Channel 33 Encoder with one track connected to
terminal 33.
[2] Signle Channel w/Dir. Encoder with one track connected to
terminal 33. The direction is set with
a signal on terminal 32: 0 V =
forward/clockwise, 24 V = reverse/
counter clockwise.
3.7.8 5-8* I/O Options
5-80 AHF Cap Reconnect Delay
Range: Function:
25 s [1 - 120 Guarantees a minimum off-time for the
*
s] capacitors. The timer starts once the AHF
capacitor disconnects and needs to expire
before the output is allowed to be on again. It
only turns on again if the frequency converter
power is 20–30%.
