AC40 CC ampl.
too low %.2s
(position)
 The position encoder signal amplitude is too
small or the contamination signal is active.
 Interruption in encoder cable
 Encoder signal amplitude missing
 Check connection of encoder.
 Check the encoder.
 Check the amplitude of the encoder signal.
 Inform your service agency.
 See ”Position encoders” on page 19 – 277.
AC50 CC freq. too
high %.2s
(position)
 The maximum input frequency was exceeded
at a position encoder input.
 Noise on encoder signal
 Check connection of encoder (ground
connection).
 Check the encoder.
 Check the input frequency of the encoder
signal.
 See ”Further examination of position and
speed encoders” on page 19 – 314.
