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:
Guarantees a minimum off-time for the
capacitors. The timer starts once the AHF
capacitor disconnects and needs to expire
before the output is allowed to be on again. It
will only turn on again if the drive power is
between 20% and 30%.
Function:
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.
