Check the Servomotor speed as fol-
lows:
D
Use the speed monitor (Un-00) of
the Digital Operator.
D
Run the Servomotor at low
speed. For example, input a
speed reference of 60 min
−
1
and
check that the Servomotor makes
one revolution per second.
Check whether the
speed reference gain
value (parameter
Cn-03) is correct.

tioning
Number of
Servomotor
revolutions
D
Input a reference equivalent to
one Servomotor revolution and
visually check that the
Servomotor shaft makes one
revolution.
Check whether the di-
viding ratio count (pa-
rameter Cn-0A) is cor-
rect.
