A.3 Drive Specifications

A.3 Drive Specifications

Note: 1. Perform rotational Auto-Tuning to obtain the performance specifications given below.

2. For optimum performance life of the drive, install the drive in an environment that meets the required specifications.

Item

<1> The accuracy of these values depends on motor characteristics, ambient conditions, and drive settings. Specifications may vary with different

motors and with changing motor temperature. Contact Yaskawa for consultation.

<2> Overload protection may be triggered when operating with 133% of the rated output current if the output speed is less than 6 Hz.

<3> Ground protection cannot be provided when the impedance of the ground fault path is too low, or when the drive is powered up while a ground

fault is present at the output.
