WARNING
When you set a new value next to the
6001-00 Programmable pulse per
object, please always check also the
object value and be sure that the resulting number of
revolutions complies with the physical number of revolutions of the device (see
the
6502-00 Number of distinguishable revolutions
16,384, see the order code).
Let's suppose that the HM58 16/16384 encoder is programmed as follows:
6001-00 Programmable pulse per revolution
= 8,192
6002-00 Programmable total measuring range
4,096 revolutions
Let's set a new singleturn resolution, for instance:
= 360 cpr
6002-00 Programmable total measuring range
value at the same time, we will get the following result:
Number of revolutions
=
33,554,432 (
= 93,206.755...
360 (
6001-00 Programmable pulse per
As you can see, the encoder is required to carry out more than 93,000
revolutions, this cannot be as the hardware number of revolutions is, as stated,
16,384 (see the
6502-00 Number of distinguishable revolutions
When this happens, the encoder falls into an error.
WARNING
Every time you enable the scaling function (bit 2
object) and/or change the value in the
scaled values (
6001-00 Programmable pulse per revolution
Programmable total measuring range
objects), then you are required to set a
object).
WARNING
Every time you change the value in this object then you are required to set a
new preset value (see the
object).
NOTE
Please refer to the “7 - Setting-up” section on page 81 for an example of how
the
6001-00 Programmable pulse per revolution
is to be set.
