Table 7-6. Taking Measures in case of operational malfunction
No Malfunction Checking points
Check motor power lines
Phase sequence of motor power lines
is not correct
5
Servomotor
accelerates
continuously
Check encoder cable
A and B phases of the encoder are
incorrect.
6
Motor vibrates
at frequencies
over 200Hz.

7
Excessive
overshoot/unde
rshoot during
start/stop.
Check for mechanical faults.
8
Abnormal
acoustic noise
Operate at low speed and check
the noise period, random or
frequent.
Inferable Causes and
countermeasures
Reduce velocity loop gain
Set torque command low pass filter
and notch filter.
－
Servo tuning with setting “High”
Lower velocity loop gain ・ Increase
integral time constant ・ Loosen
acceleration / deceleration
command pattern
Use position command low pass
filter
Operate servomotor with no load
Check centering and unbalance on
coupling
Check if encoder signal line is pair-
twisted and shielded.
Check if encoder and power lines
are put together in the same duct.
Check if power supply voltage
drops.

Inspection of the Controller
7.9.3. Maintenance
As the Servomotor and amplifier have no wearing parts, the user has only to check
routinely. The check item, timing, and procedure are indicated as follows.
1. Performing of megger test of the Servo Amplifier
may damage the amplifier, we recommend that
you conduct a continuity check using the tester.
Caution
2. Do not remove the cover from the detector of the
Servomotor.

1. Prior to cleaning, make sure that the air does not
contain water or oil.
2. This means the check/replacement interval when
a water –proof or oil-proof function is required.
Caution
3. Be advised that estimated life of our
recommended battery (Toshiba lithium battery
ER3V: 3.6V, 1000mAh) is about 2 years on the
condition that power supply remains OFF.
