It uses PWM constant current drive technology and supports communication via RS485 with MODBUS RTU protocol, allowing up to 30 nodes on the bus. The driver features configurable digital inputs and outputs, including pulse, direction, encoder signals, and status LEDs for fault and operation indication. It is suitable for precise location and speed control modes with a compact form factor measuring 156mm by 97mm by 33.5mm.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cul\u003eKey Specifications\u003cul\u003e\n\u003cli\u003eInput Voltage: DC 24V to 72V\u003c\/li\u003e\n\u003cli\u003eMaximum Output Current: 6.0A (peak)\u003c\/li\u003e\n\u003cli\u003eMotor Type: 2-phase bipolar stepper motor with encoder\u003c\/li\u003e\n\u003cli\u003eDrive Mode: PWM constant current\u003c\/li\u003e\n\u003cli\u003eCommunication Interface: RS485, MODBUS RTU protocol\u003c\/li\u003e\n\u003cli\u003eControl Modes: Location and speed control\u003c\/li\u003e\n\u003cli\u003eDigital Inputs\/Outputs: Configurable pulse, direction, encoder signals\u003c\/li\u003e\n\u003cli\u003eDimensions: 156mm (L) x 97mm (W) x 33.5mm (H)\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: 0 to 45°C, 85% RH max\u003c\/li\u003e\n\u003cli\u003eWeight: Approximately 376g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAt \u003cb\u003eEssential Parts\u003c\/b\u003e, we offer \u003cb\u003efast shipping\u003c\/b\u003e, \u003cb\u003elowest price\u003c\/b\u003e, and \u003cb\u003eexpert support\u003c\/b\u003e to help you get the right product every time.\u003c\/p\u003e \t\t\t\t\t\t\t\t\t\t\u003cbr\u003e                                          \t\t\t\t\t\t\t\t\t\t\u003ch3\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/h3\u003e \t\t\t\t\t\t\t\t\t\t\u003cul\u003e \t\t\t\t\t\t\t\t\t\t\t\u003cli\u003ePart Number: FRS4-1\/2\u003c\/li\u003e                                              \t\t\t\t\t\t\t\t\t\t\u003c\/ul\u003e                                         \u003cbr\u003e                                         \u003ch3\u003e\u003cb\u003eProduct Data\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003eWeight : 5.19 \u003c\/li\u003e\u003c\/ul\u003e                                         \u003cbr\u003e                                          \u003c\/ul\u003e","brand":"Essential Electric Supply","offers":[{"title":"Re-Certified","offer_id":53010833014943,"sku":"FRS4-1\/2-ReCert","price":0.0,"currency_code":"USD","in_stock":false}],"url":"https:\/\/essentialparts.com\/products\/frs4-1-2","provider":"Essential Electric Supply","version":"1.0","type":"link"}
