Important note for multiturn encoder operation
This encoder
supports „Endless Operation“ automatically if required.
Thus, there are no special requirements for the encoder parameters
“total measuring range” and “measuring
units per revolution ” to stand in a certain ratio.
With endless operation active, the encoder shaft must not rotate when the encoder is not powered. In
those cases where powerless motion cannot be avoided, the encoder has to be referenced (presetted) after
each power-up. With Endless Operation inactive, the encoder shaft may rotate unlimited when encoder not
powered.
How to determine if „Endless Operation“ is in use:
Multiply the encoder’s „max. possible revolutions“ (depending on encoder 16 bit = 65536 or 13 bit =
8192) by your chosen parameter
„measuring units per revolution“.
Divide this value by your chosen „total measuring range“.
If there is a division remainder, endless operation is in use.
Example for parameters without endless operation:
Maximum possible revolutions
65536 (16 bit multiturn)
Measuring units per revolution 3600
Total measuring range 29.491.200 (8192 x 3600)
Calculation: 65536 x 3600 / 29.491.200 = 8 (no remainder)
Example for parameters with endless operation:
Maximum possible revolutions
65536 (16 bit multiturn)
Measuring units per revolution 3600
Total measuring range 100.000
Calculation: 65536 x 3600 / 100.000 = 2359 remainder 29600
