Function:
revolution on the motor shaft. Read
the correct value from the encoder.
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.
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:
NOTICE
This parameter is only available
with software version 48.XX.
Select the signal type of the encoder
connected to terminals 32, 33.
Encoder with 2 tracks: A and B, displaced
90° for detecting the rotational direction.
Encoder with 1 track connected to
terminal 33.

Table 3.22 Bus-controlled Digital Outputs and Relays
Function:
Encoder with 1 track connected to
terminal 33. The direction is set with a
signal on terminal 32: 0 V = forward/
clockwise, 24 V = reverse/counter
clockwise.
Function:
Guarantees a minimum off-time for the
capacitors. The timer starts once the AHF
capacitor disconnects and has to expire before
the output is allowed to be on again. It only
turns on again if the frequency converter
power is 20–30%.
Function:
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.
