35 Backpack-type Integrated Motor (Pulse)

Product Overview

The LC35BK-P integrated stepper driver features a revolutionary design, with a core advantage of ultra-compact structure, integrated wiring port layout, saving equipment space and reducing wiring complexity. Built-in high-precision encoder (resolution 16384PPR), combined with closed-loop feedback algorithm, positioning can reach ±0.02°, effectively eliminating the risk of missing steps, suitable for high-precision positioning scenarios. This driver supports two control modes: pulse mode and IO, which can be switched through software settings, flexibly adapting to different working occasions.

Features

Power supply voltage: DC 20V to 30V Output peak current: 2.5A Communication interface: Pulse Pulse input frequency: 200KHZ Communication protocol: Modbus RTU With overcurrent, overvoltage, excessive deviation and other alarm protection functions
