7ST30I00

Product catalog summary

Introduction
The 7ST30I00 is a 4-quadrant driver designed for PMDC gearmotors powered by 24V or 36V batteries. It provides position control using a joystick reference signal and feedback from an optical encoder. The system includes a microprocessor for digital control, diagnostics, and programming. The power stage uses an H-bridge configuration with PWM technology at 16 KHz and complies with EC standards.

- INTRODUCTION The controller 7ST30I00 is a 4 quadrant driver for PMDC gearmotors powered by battery 24V or 36V that provides a position control by mean of a reference signal (joystick) and a feedback signal (optical encoder on the steering system axe or on the steering gearmotor) . The driver is equipped with a powerful microprocessor for digital control of the gearmotor (position, speed, acceleration, current) , failures and diagnostics analysis of the system and programmation. The power stage is an “H bridge” configuration that operates with the PWM technology at 16 KHz. The driver is designed...
