 Motor’s rated frequency (Pr.01-03) changes as Rated speed of the synchronous motor (Pr.01-19) and
Number of poles of the synchronous motor (Pr.02-120) change.

Factory setting: 220.0/440.0
Settings 230V models: 0.1 – 255.0V
460V models: 0.1 – 510.0V
 Typically, this setting is configured according to the rated operation voltage shown on the motor’s nameplate.
If the motor is intended for 220V, set this value as 220.0V; if the motor is intended for 200V, set this value as
200.0V.

 The acceleration time determines the time required for the hybrid servo motor to accelerate from 0.00Hz to
[the motor’s maximum frequency] (Pr.01-02). The deceleration time determines the time required for the
hybrid servo motor to decelerate from [the motor’s maximum frequency] (Pr.01-02) to 0.0Hz.

 If the parameter is set as 1~2, it will perform the parameter automatic tuning for the Induction motor. In this
case, press the [Run] button to perform the automatic measurement operation immediately. After the
measurement is complete, the values are filled into Pr.01-13 ~ Pr.01-16 (no-load current, Rs, Rr, Lm, and Lx),
respectively.
Induction motor AUTO-Tuning procedure: (Rolling test)
1. All parameters of the hybrid servo drive are set to factory settings and the motor is connected correctly.
2. Users are strongly advised to disconnect the motor from any load before tuning. That is to say, the
motor contains only the output shaft and connects to neither a belt nor a decelerator. Otherwise, it will
be impossible to disconnect the motor from any loads. Static tuning is advised※.
