(2) Spindle data used for adjustment
Adjust the parameters while observing the motor speed, torque
command, velocity error, synchronous error, and other waveform by
using a spindle check board and oscilloscope or SERVO GUIDE. The
table below lists spindle check board settings for observing the
waveform.

NOTE
When observing the synchronous error of Series 16i, set the
following parameters:
No. 3700, #7 = 1:
Uses the synchronous error output (maintenance function).
(Return the setting to 0 after the observation is completed.)
No. 5203, #7 = 1 :
Sets a synchronous error update cycle.
(Return the setting to 0 after the observation is completed.)
No. 5204, #0 = 0 :
Displays the synchronous error on the diagnosis screen.
