(2) Operating Procedure

Use the following procedure.

CAUTION

• 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.
