Step Description Check Method and Remarks
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 the input signal circuit.
2 Turn ON the servo ON (/S-ON) input signal.
If the servomotor rotates at an extremely slow speed, refer to
4.5.3 Adjusting Reference Offset, 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 servo drive
(Un001[rpm])
Refer to 5.1.6 Operation in Monitor Mode.
5 Check the Un000 (motor speed [rpm]) Refer to 5.1.6 Operation in Monitor Mode.
6
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, refer to 4.3.2
Switching the Servomotor Rotation Direction.
Perform the operation from step 2 again after the servomotor
rotation direction is changed.
8
When the speed reference input is set to 0 V and
servo OFF status enters, trial operation for
servomotor without load is completed.
