Troubleshooting
Section 11-1
51 The motor axis is
vibrating
unsteadily. The gain adjustment is
insufficient. (The gain is too
low.) • Perform auto-tuning.
• Manually adjust (increase) the
gain.
52 The gain cannot be
adjusted because the
mechanical rigidity is too
weak. This particularly tends to occur
in systems with vertical axes,
scalar robots, palletizers, and so
on, which place a torsion load
on the axes. • Increase the mechanical rigid-
ity.
• Re-adjust the gain.
53 The mechanical structure is
producing stick slip (high-
viscosity static friction). • Perform auto-tuning.
• Manually adjust the gain.
54 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.
55 The Servomotor or the
Servo Driver is defective. Replace the Servomotor or the
Servo Driver.
56 There is slip-
page in position-
ing. The slippage is not con-
stant.
Malfunction due to noise.
Is specified cable being used? Use specified cable.
57 The shield is not properly
grounded at the Servo
Driver. Check the ground wiring. Correct the wiring.
58 The cable between the MC
Unit and the Servomotor is
too long. The maximum cable length is 50
meters.
59 The cable between the MC
Unit and the Servo Driver is
not separated from other
power lines. Check whether the cable is sep-
arated from other power lines. Separate the cable from other
power lines.
60 There is malfunctioning
due to noise from a welding
machine, inverter, etc. Check whether there is a device
such as a welding machine or
inverter nearby. Separate the Unit from the
noise source.
61 There is slippage in the
mechanical system. Check for slippage by marking
the mechanical connections. Tighten the connections.
62 Communica-
tions Alarm is
generated. There is incorrect connec-
tion of communications
cable between the MC Unit
and MLK devices. Check the communications
cable connection and breaking
of wire. • Correct wiring of the communi-
cations cable.
• Replace the communications
cable.
63 The MC Unit
cannot receive
absolute data
(when an abso-
lute encoder is
used). The Servo Driver’s setup
parameters are not correct. W Series:
Turn Off (0) Servo Driver param-
eter Pn002 digit No.2.
64 The absolute
value read at
turning ON is dif-
ferent from the
one at turning
OFF. (when an
absolute
encoder is
used). There is mechanical slip-
page. Check whether the motor turns
while the power is OFF.
65 The Servo Driver parame-
ter settings are not correct. Check the Servo Driver parame-
ters. Turn Off (0) Servo Driver param-
eter Pn000 digit No.0 of the
