Set the spindle pitch
ISDU 116 (numerator factor) and 117 (denominator factor) can be used to modify the
instrument’s spindle resolutions to any desired numerical value.
𝑁𝑜. 𝑜𝑓 𝑖𝑛𝑐𝑟𝑒𝑚𝑒𝑛𝑡𝑠 𝑝𝑒𝑟 𝑟𝑜𝑡𝑎𝑡𝑖𝑜𝑛 = 400 ∗
𝐷𝑒𝑛𝑜𝑚𝑖𝑛𝑎𝑡𝑜𝑟 𝑓𝑎𝑐𝑡𝑜𝑟
𝑁𝑢𝑚𝑒𝑟𝑎𝑡𝑜𝑟 𝑓𝑎𝑐𝑡𝑜𝑟
Both factors are set to a value of 400 by default, resulting in a resolution of 0.01 mm at a
spindle pitch of 4 mm.
The denominator factor is a simple way to set the spindle pitch and resolution.
The numerator factor is primarily used for setting “unlevel” resolutions.
Examples:
Spindle pitch

Note:
Numerator and denominator factors may take on values between 1 and

Aborted run when the master fails
If the connection to the master is interrupted during a positioning run, the master cannot
abort a run that is already underway.
In this case, there are two possible responses:
1) If a positioning run is in progress, the drive should
complete this positioning
run as planned
. It should then not start any new positioning run until a
connection has been re-established.
This response is activated when ISDU 162 (“Communication timeout”) is
set to 0.
