The parameter is writable. The controller rejects an input value, which is greater or equal
than the value "Revolutions overflow counter maximum value" (
Z106.16–).
The overflow counter can be used for the following functions
m Addition of the overflow count revolutions to the actual positioning value (Z106.11– or
Z106.12–) at the encoder initialization. The Activation of the function is made by
Z106.3– encoder options bit 10.
m Z121.17– modulo actual position value and Z121.12– actual position value with over-
flows. The activation of this function is made by Z121.1– positioning general mode
bit 4.
106.16 Revolution overflow counter max value
This parameter specifies the maximum counter limit for the encoder revolution overflow
counter (
Z106.15–) from which the overflow counter starts with 0 again.
If the value of the parameter is equal to 0 or 1, the parameter Z106.15– does not count.
The parameter is writable. The value Z106.15– is adapted to the new counting range ac-
cording to a modulo calculation, if a smaller value than the present value of Z106.15– is
written.
106.20 Offset sine
Offset correction for the sine signal. Automatically adjusted when optimization activated.
Can also be set as a fixed parameter.
106.21 Offset cosine
Offset correction for the cosine signal. Automatically adjusted when optimization activat-
ed.
Can also be set as a fixed parameter.
NOTE!
At singleturn encoders as well as at resolvers the overflow count operates as well.
The correctable ¼ revolution range is a +-¼ encoder revolution. Therefore the over
-
flow count can not be corrected even after a revolution which is greater than a ¼ rev-
olution in the switched off status. After an encoder error at a rotating motor the
permitted revolution can be exceeded from the encoder information loss onward. In
both cases the overflow count of the encoder is incorrect after a restart or a re-initial
-
ization!
At incremental encoders the overflow count cannot be used.
