4.3. Further additional functions
•
C004 Switch-on display
Entering a code number under C004 determines which
parameter is to be displayed after switching-on.
•
C018 Chopper frequency
The chopper frequency determines the noise level. The chopper
frequency can either be 8 or 16 kHz. Changing the chopper
frequency changes the admissible permanent load of the axis
module.
•
C255 Following error limit
If an following error exceeds the value entered under C255
during master frequency operation (C005 = -13- or -21-) and an
amplification of the angle controller of C254 > 0, an internal
signal will be generated for the error status >>Following error
limit exceeded<< . If this signal is applied to the terminal Q
min
(X5,42) via C117, the Q
min
terminal will change its level from
HIGH to LOW as soon as the set limit value is exceeded.
For following errors of more than 3188 increments, also the
RDY message will be set to LOW and >>following error<< will
be displayed.
