Detection Condition Formulas
An alarm is detected if either of the following two conditions is met.
Pn585 [mm/s]
•
Linear scale pitch [µm]
Pn385 [100 mm/s]
•
Linear scale pitch [µm]
Cause Investigative Actions
−
Check the capacities to see if they
satisfy the following condition:
(Servomotor capacity)/(SERVO-
PACK capacity) ≥ 1/4, and (Servo-
motor capacity)/(SERVOPACK
capacity) ≤ 4.
Replace the servomotor and see if
the alarm occurs again.
−
Check the product specifications,
and select the correct model.
Check the parameter setting
(Pn01E.0) and the servomotor that
is used in combination with the
SERVOPACK.
Check the model of the combined
servomotor from the product infor-
mation monitor in SigmaWin for
the Σ-V-SD (MT).
Check the parameter setting
(Pn01E.0) and the servomotor that
is used in combination with the
SERVOPACK.
Check the parameter setting
(Pn01E.1) and the motor that is
used in combination with the SER-
VOPACK.
Check the model of the combined
servomotor from the product infor-
mation monitor in SigmaWin for
the Σ-V-SD (MT).
