Troubleshooting
The Servomotor is
making strange
noises.
Servomotor oscil-
lates at approx.
200 to 400 Hz.
Frequency over-
shooting when
starting and stop-
ping is too high.
Symptom
There is interference due
to the encoder being sub-
jected to excessive vibra-
tion and shock.
Encoder is defective.
The speed loop gain
(Pn100) is set too high.
The position loop gain
(Pn102) is set too high.
The speed loop integral
time constant (Pn101) set-
ting is inappropriate.
The machine rigidity set-
ting is inappropriate.
The inertia ratio (Pn103)
data is inappropriate.
The speed loop gain
(Pn100) is set too high.
The position loop gain
(Pn102) is set too high.
The speed loop integral
time constant (Pn101) set-
ting is inappropriate.
The machine rigidity set-
ting is inappropriate.
The inertia ratio (Pn103)
data is inappropriate.
Probable cause
• Check for machine vibra-
• Encoder is defective.
• Default: Kv = 80.0/Hz
• Default: Kv = 40.0/Hz
• Default: Ti = 20.00 ms
• Check the machine rigidity
• Check the inertia ratio
• Default: Kv = 80.0 Hz
• Default: Kp = 40.0/s
• Default: Ti = 20.00 ms
• Check the machine rigidity
• Check the inertia ratio
