Troubleshooting 4 (Motor operation is not steady)
The motor operates unsteadily.
Table 9.3.4
Cause What to do
FG and GND connection is wrong. Connect FG and GND correctly.
Speed and position command is not steady. Check the contact of cables and connectors.
Misadjustment Adjust the parameters.
The motor rotate without host command input. Set the appropriate values for No.33.0
「
Pulse train command - Input filter
selection
」
in position control mode.
Adjust parameter No.60.0
「
Analog speed command - Fixed offset
value
」
in speed control mode.
Adjust parameter No.300.0
「
Analog torque command Fixed offset value
」
in torque control mode.
Command is interfered. The shielded twisted-pair cable is used for I/O cable in a vulnerable
environment. So is the encoder cable. The encoder cable should be 20m
or less.
Position deviation occurs. Set the appropriate values for No.33.0
「
Pulse train command - Input filter
selection
」
in position control/pulse train command mode. Check whether
the pulse output of host control device (such as PLC) is beyond the limit
value. Check whether the product of
①
No.33(Pulse command
input(position) and host control device output,
②
No.65(Position
command) and No.67(Position feedback),
③
No.67 and parameter
No.276.0/278.0(Encoder pulse output division and multiplication) is
consistent with the position feedback of host control device. If inconsistent,
it may be interfered. Then connect FG correctly and adjust parameter
No.33.0.
Please use shielded twisted-pair for I/O cable.
Deviation occurs when home position reset. Check the command input of host control device. Check whether to get the
Z-phase correctly from the host control device. If the Z-phase pulse
amplitude is small, adjust No.276.0 and 278.0
「
Encoder output division
and multiplication
」
to increase the pulse amplitude.

Troubleshooting 5(Vibration and sound)
Vibration and sound occurs when the motor operates.
Table 9.3.5
Cause What to do
Large gain Adjust the gain.
The machine or devices loosen. Check the installment of motor, reducer and coupling.
Interference occurs. Check the cables’ length and shielding.
The high-voltage cable(motor power cable) should be isolated from the
signal cable (encoder cable).
Resonance occurs between motor and device. Adjust position command smoothing filter at low-vibration; Adjust low-pass
filter or notch filter at high-vibration.
