When Performing Position Control From The Host Controller - YASKAWA SGM series User Manual

2) When performing position control from the host controller

Check motor operation first and then conduct a test run as described in the table below.
NOTE Check the motor operation with the motor disconnected from the machine. If the host con-
troller does not perform position control correctly, the motor may run out of control.

example, input a
speed reference of
60 r/min and check
that the motor
makes one
revolution per one
second.
D Input a reference
equivalent to one
motor revolution
Number of motor
and visually check

without
load
Check Method Review Items
Check whether the
speed reference gain
value (user constant
Cn-03) is correct.
Check whether the
dividing ratio count
(user constant
Cn-0A) is correct.
If the motor does not
stop, review the
P-OT and N-OT
wiring.
