Troubleshooting
Section 11-1
32 Motor rotation is
unstable. The parameters are set
incorrectly. Check the MC Unit parameters
with the Support Tool. Set the parameters correctly,
transfer them to the MC Unit,
and write them to flash memory.
33 The Servo Motor power
lines and encoder lines are
wired incorrectly. Check the Servo Motor power
lines and encoder lines. Correct the wiring.
34 There is eccentricity in the
couplings connecting the
Servomotor axis and the
mechanical system. There
may be loose screws or
load torque fluctuation due
to the meshing of pulley
gears. Check the machinery.
Try turning the motor with no
load (i.e., with the machinery
removed from the coupling). Adjust the machinery.
35 The gain adjustment is
insufficient. • Execute Servomotor auto-tun-
ing.
• Manually adjust the Servomo-
tor gain.
• Adjust the servo parameters
with the Support Tool.
36 Motor rotation is
unstable. The wrong Servomotor is
selected (so it cannot be
adjusted). Check the torque and inertia
ratio and select another Servo-
motor. Change to a suitable Servomo-
tor.
37 The Servomotor bearings
are damaged. Turn OFF the Servo Driver
power. If the Servomotor has a
brake, turn ON the brake power
supply and release the brake,
and then manually turn the
motor’s output shaft with the
motor’s power line disconnected
(because the dynamic brake
may be applied). Replace the Servomotor.
38 The Servomotor windings
are disconnected. With a tester, check resistance
between the Servomotor’s U, V,
and W power lines. There
should be a proper balance
between the line resistances. Replace the Servomotor.
39 Rotation is
reversed. The Servo Driver is set for
reverse rotation. Check the System Parameter
setting using the Support Tool. Correct the setting for the direc-
tion of Servo Driver rotation.
40 During an origin search:
The origin proximity sensor
polarity does not match the
parameter setting (in the
MC Unit) for the origin prox-
imity input polarity. Check the parameter setting
and the sensor polarity. Correct the parameter setting.
41 During an origin search:
The origin proximity input
wiring is faulty. With the Support Tool, check
whether the origin proximity
input status is correct. Correct the origin proximity
input wiring.
No. Problem Probable causes Item to check Remedy
