Toshiba H7 Low Voltage Standard Duty Industrial Drive

The H7 Adjustable Speed Drive is ready for continuous, trouble-free operation in demanding manufacturing environments. It features open or closed loop true torque control, which is Toshiba’s vector algorithm that enables motors to develop high starting torque compensation for motor slip. A graphics capable, back-lit LCD display, RS485/RS232 ports and a programming/speed control encoder round off this advanced drive. The H7 is suitable for a variety of applications that require unparalleled motor control, rugged reliability and a user-friend operator interface.
