(2) Operating Procedure
• When using the SERVOPACK with Jcalc = OFF (load moment of inertia is not cal-
culated), be sure to set a suitable value for the moment of inertia ratio (Pn103). If
the setting greatly differs from the actual moment of inertia ratio, normal control of
the SERVOPACK may not be possible, and vibration may result.
• When using the MP2000 Series with phase control, select the mode = 1 (standard
level). If 2 or 3 is selected, phase control of the MP2000 Series may not be possi-
ble.
Use the following procedure.

Select the mode to be used.
Usually, set Jcalc to ON.
Jcalc = ON: Moment of inertia calculated [Factory setting]
3-1
Jcalc = OFF: Moment of inertia not calculated
Note:
If the moment of inertia ratio is already known from the machine specifications, set the value in
Pn103 and set Jcalc to OFF.
Mode Selection
Select the mode.
