The drives belonging to the DS5x series are provided with fieldbus in standard Modbus-RTU. The available interfaces allow the connection in RS232, RS485 and USB. Up to 247 different drives, even of different power size, can be connected to the same bus and can be addressed singularly or with global commands (executed at the same time by all drives connected to the fieldbus). The DS5x drives, realized with the newest digital technologies, offer high performances without compromises. With a resolution at 1/128 of step (equivalent to 25,600 step/rev with a 1.8° motor) they can drive the motor up to 3,000rpm allowing in many cases to substitute very expensive servo systems. The product range is complete and allow to choose amongst products with supply voltage from 20Vdc up to 240Vdc and phase current from 0.8Arms up to 10Arms (corresponding to more than 14Apk). The extremely compact dimensions reach a maximum size of just 35x100x120mm. The removable terminal blocks and the easy installation on DIN rail contribute to make the DS5x drives series the ideal choice for the modern industrial automation requirements.
