1
Check the power and input signal circuits
again, and check that the speed reference
input (voltage between the V-REF+ and V-
REF-) is 0V.
Refer to the above figure for input signal circuit.
2
Turn ON the servo ON (/S-ON) input signal.
If the servomotor rotates at extremely slow speed,
refer to

and use
the reference voltage offset to keep the servomotor
from moving.
3
Generally increase the speed reference
input voltage between V-REF+ and V-REF-
from 0 V.
The factory setting is 6V/rated rotation speed.
4
Check the speed reference input to the
servodrive (Un001[min
-1
])

Check that the Un001 and Un000 values in
steps 4 and 5 are equal.
Change the speed reference input voltage and
check that Un001 and Un000 are equal for multiple
speed references.
7
Check the speed reference input gain and
servomotor rotation direction.
Refer to the following equation to change the speed
reference input gain (Pn300).
Un001
＝
(V-REF Voltage)[V]×Pn300
To change the servomotor rotation direction without
changing polarity for speed reference input voltage,
