LCDA257-3A Three-Axis Closed-Loop Driver

Product Overview

LCDA257-3A is a 3-axis digital two-phase stepper driver designed with a dual ARM core architecture, which be adapted to 42, 57, and 60 series two-phase stepper motors. This driver uses the latest gantry drive algorithm to achieve better dualaxis motor synchronization performance, and the 3 axes can be independently controlled. The driver combines many years of motion control algorithms, greatly reducing the heat and noise of the motor during operation making the motor run more smoothly and reliably.

Features

Voltage input range: DC24V to 50V Maximum peak current: 5.6A (modifiable via debugging software) Subdivision range: 200 to 60000 ppr Pulse form: Pulse + Direction, CW + CCW (set via debugging software) Pulse response frequency: 0 to 200KHz Pulse stop 1.5S, coil current automatically reduced to half the set value Features overvoltage, overcurrent, and other protection functions
