The link is to a pdf manual that you most likely have.
Page 3 has the input scale type and resolutions that the Display is compatible with. This is them here.
Only Spherosyn or Microsyn encoders can be used with the DP700 DRO
Input and Resolutions
Spherosyn 2G or Microsyn 10 ,5µm (0.0002″), 10µm (0.0005″), 20µm (0.001″), 50µm (0.002″)
Input & Resolutions
Microsyn 5 , 1µm (0.00005″), 2µm (0.0001″), 5µm (0.0002″), 10µm (0.0005″)
Page 7 has the setup information.
You need to enter the 4 digit code to get to the setup. The default 4 digit code is 1937
Then goto the Setup encoder, and toggle through the 3 options,
SPH 2G (Spherosyn 2G),
USN 10 (Microsyn 10),
USN 5(Microsyn 5)
Then set the SetUp Resolution and toggle through to match that of your scales.
By default there is no linear compensation set.
The most common cause for the scale reading being out is an incorrect scale setting.
We have the power go out at work, and sometimes it does not save the encoder information. So every once in a while it requires to go back into the parameters and needs to be reset to the actual units. We have the Microsyn 5, 1um for the cross slides, and the Microsyn 10 , 5um for the carriage. We also have the DP1200 on some lathes too.
1937 is the code required for all of them at work for any changes that need to be edited. Each has it’s own little book of Settings and the encoder type fitted to that machine.
None of the 4 lathes are requiring to use the error compensation.
This should get you in the right direction.
