NJ101 series servo drvier

*1. Rated totation speed:when full load, speed ratio is defined as the minimum speed[the motor will not pause]
*2. When command is rated rotation speed, the speed fluctuation rates is defined as [Empty load rotation speed full load rotation speed] rated rotation speed.
*3. TN system:A power distribution system having one point directly earthed, the exposed conductive parts of the installation being connected to that points by protective earth conductor.
