Analog Input Signals - KEB ACOMBIVERT F5 X3A Instructions For Use Manual

The output signals of tracks A and B are dependent on the encoder line number. If the en-
coder line number, adjusted in parameter Ec.01, is not correspond with the actual encoder
line number, an error will be triggered immediately after revolution of the rotor axis.
The zero track will permanently be compared with the position. In case a difference occurs
the position will be corrected with a ramp time after a filter. In addition the position value
of the absolute track (C and D) will be compared with the position any 30 ms. Since the
absolute track is relatively inaccurate, corrections are only made until a valid zero signal is
recognized. Then only an error is released, if the difference exceeds a maximum value.
If no absolute and/or zero track is recognized during power-on, this functions are
getting deactivate. Operation with exclusively utilization of the high resolution
tracks A and B is possible.
