Introduction - Toshiba T300MVi MEDIUM VOLTAGE Instruction Manual

INTRODUCTION

Thank you for purchasing the T300MVi Medium Voltage ASD. This adjustable frequency, solid-
state AC drive features a 3φ input isolation transformer with a 24-pulse converter design, a 32-bit CPU, and
a three-unit power module inverter section providing a 5 level output for 4160/3300V drives and 3 level
output for 2400V drives. The T300MVi also features as standard, an 8 key Control Panel with a LCD screen
and 2 discrete LED lamps to indicate Ready, Run, Local, Remote and Alarm/Fault.
On most power systems, this drive will meet IEEE-519-1992 harmonic regulation guidelines without
installing additional harmonic filters. The input power factor is typically 0.95. The multi-level output
produces a more sinusoidal voltage and reduces stress on the motor winding insulation. This drive uses
high capacity 3300V IGBTs to improve reliability, reduce switching losses, and improve control performance.
The PP7 control processor and 6-layer control board achieves high integration and reliability.
