KEB ACOMBIVERT F5 X3A - Analog Input Signals

SIN/COS at Channel 1
GB -9
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di󰘯erenceoccurs
thepositionwillbecorrectedwitharamptimeaftera󰘰lter.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di󰘯erence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.
