Cautions on Replacing the Motor

As stated above, torque limit setup range might change when you replace the combination of the motor and the driver. Pay attention to the followings.

1.When the motor torque is limited,

When you replace the motor series or to the different wattage motor, you need to reset the torque limit setup because the rated toque of the motor is different from the previous motor. (see e.g.1)

(0.19N•m x 337% = 0.64N•m)

2.When you want to obtain the max. motor torque,

You need to reset the torque limiting setup to the upper limit, because the upper limit value might be different from the previous motor. (see e.g.2)
