Resolution of linear analog encoder
If Renishaw analog encoder is used, the straight distance of one sine wave
or one cosine wave is 10 um. Then the line is 10 um/line. If analog encoder
multiplier factor is 250, the actual resolution is:
10 / ÷ (250 × 4) = 0.00001 /
Explanation of term
Line:
The position feedback signal of analog encoder consists of sine wave and cosine wave. The length
of one sine wave is called one line or grating period.

Step 16: Check the motor velocity. Use Scope to check if Motor velocity is in accordance with the pulse
velocity.
Step 17: Check if the input command pulse velocity and the motor velocity are the same (The values in
step 15 and 16 are the same.).
Step 18: The controller stops inputting pulse commands.
Step 19: The controller stops inputting S-ON signal. The servo drive becomes servo OFF.
If any of the result in the above step is incorrect, check the settings by referring to
sections 7.1~7.6 and 9.2.
If the actual operation is different from the pulse command, please check the
electronic gear ratio and wiring.
