53 Vibration is
occurring at the
same frequency as
the application
frequency. Inductive noise is being
generated. Check whether the Servo Driver
control signals are too long.
Check whether the control signal
lines and power lines are
bundled together.
Shorten the control
signals.
Separate the control
signal lines and the
power lines.
Use a low-impedance
power supply for the
control signal lines.
54 The control signals are not
properly grounded. Check whether the control signal
shield is properly grounded at
the Servo Driver.
Check whether the control signal
lines are in contact with the
ground.
Correct the wiring.
55 Twisted-pair or shielded cable
is not being used between the
MC Unit and the Servo Driver. Check whether twisted-pair
cables are used for the encoder
signals and speed references,
and whether the cables are
shielded. Use twisted-pair and
shielded cable as in the
wiring examples.
56 The motor axis is
vibrating unsteadily. The gain adjustment is
insufficient. (The gain is too
low.) --- Perform autotuning.
Manually adjust
(increase) the gain.
57 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
rigidity.
Re-adjust the gain.
58 The mechanical structure is
producing stick slip (high-vis-
cosity statical friction). --- Perform autotuning.
Manually adjust the gain.
59 The wrong Servomotor is
selected (so it cannot be
adjusted). Check the torque and inertia
ratings and select another
Servomotor. Change to a suitable
Servomotor.
60 The Servomotor or the Servo
Driver is defective. --- Replace the Servomotor
or the Servo Driver.
