WARNING
When you set a new value next to the
always check also the
sure that the resulting number of revolutions complies with the
Hardware number of revolutions of the device.
Let's say our encoder is programmed as follows:
Counts per revolution: 8192
Total resolution = 33554432
Let's set a new total resolution, for instance:
As the Total resolution
per revolution, the above setting is not allowed. When this happens,
the encoder falls into an error signalling the faulty condition through
the diagnostic LEDs (see on page 12).
Example
"HS5818/FB-xx": singleturn encoder
 Hardware counts per revolution
 Hardware number of turns
 Total hardware resolution
"HM5816/16384/FB-xx": multiturn encoder
 Hardware counts per revolution
 Hardware number of turns
 Total hardware resolution
Example
Multiturn encoder "HM5816/16384/FB-6" with "BC-PB-C" connection
cap.
Resolution is:
 Hardware counts per revolution = 65536 (2
 Hardware number of turns
 Total hardware resolution
