LCDA616H Two-Phase 57/60 Digital Display Servo Driver

Product Overview

The LCDA616H driver is a digital stepper driver developed using the latest generation 32-bit DSP chip. It is designed to control closed-loop stepper motors with 57/60 frame sizes. This driver supports three control modes: pulse, IO, and analog.

Features

Voltage input range: DC24V~50V Maximum peak current: 6A Subdivision range: 400~51200ppr Signal input: differential/single-ended, pulse/direction or dual pulse Pulse response frequency: 200KHz Parameters can be configured via serial port Supports three control modes: pulse, IO, and analog Features protection functions including overcurrent, overvoltage, undervoltage, phase loss, and excessive position deviation

Driver Terminal Description

(1) Control Terminals

Terminal Name	Description
GND	Analog output interface, outputs 0-5V analog voltage
AO	Analog output interface, outputs 0-5V analog voltage
GND	Analog control interface, can be used as speed control input signal, can use the driver's 5V external potentiometer control, or external analog control.
AI
5V
ALM-	Alarm output signal, requires external 24V power supply; when axis 1 motor alarm occurs, signal is output through the alarm port. (Default is normally open interface, i.e., signal output during alarm; can be changed to normally closed output by setting parameter PA-21 to 1 via software communication, meaning signal is cut off during alarm.)
ALM+
BRK-	Brake control signal, can be changed to positioning completion signal, requires external power supply, drives external relay.
BRK+
ENA-	Enable control signal, this input signal is used to enable or disable the driver outputs of axis 1 and axis 2. When ENA is connected to low level (or internal optocoupler conduction), the driver will cut off current to all motor phases, putting the motor in free state and not responding to step pulses. If this function is not needed, leave the enable signal terminal floating. (Signal voltage supports 5-24V)
ENA+
DIR-	External pulse mode : Used as direction input, signal voltage supports 5V-24V; pulse input mode: pulse + direction (used as direction input), dual pulse (used as CCW input); high/low level signal. To ensure reliable motor direction change, the direction signal should be established at least 5μs before the pulse signal.
DIR+
PUL-	External pulse mode : Used as pulse signal input, signal voltage supports 5V-24V; pulse input mode: pulse + direction (used as pulse input), dual pulse (used as CW input); pulse effective edge is adjustable, default is rising edge; to reliably respond to pulse signals, pulse width should be greater than 2.5μs.

Terminal Name	Description
A+	Motor phase A and phase B winding interface Motor rotation direction can be switched via PN-27

B-
VDC	Voltage input terminal: supports DC 24~50 VDC recommended power supply DC36V, 5A or above

(3) Encoder Wiring Terminals

Terminal Name	Description
EB+	Motor encoder phase B positive feedback pulse pin
EB-	Motor encoder phase B negative feedback pulse pin
EA+	Motor encoder phase A positive feedback pulse pin
EA-	Motor encoder phase A negative feedback pulse pin
EZ+	Motor encoder phase Z positive feedback pulse pin
EZ-	Motor encoder phase Z negative feedback pulse pin
E5V	Motor encoder power positive terminal (Voltage +5V)
EGND	Motor encoder power negative terminal

Alarm Handling

Number of flashes	Description	Fault Handling
ERR001	Overcurrent	1. Motor power line short circuit or motor fault; 2. Motor phase sequence wiring, check phase sequence; 3. Incorrect motor model setting, check motor model; 4. Overload, try running without load to check if normal; 5. Gain parameter set too high, reduce gain parameter; 6. Internal driver fault, return for repair.
ERR002	Overvoltage	1. Check if supply voltage is too high, reduce voltage or replace power supply; 2. Internal driver fault, return for repair.
ERR003	Undervoltage	1. Check if supply voltage is too low, increase voltage or replace power supply; 2. Internal driver fault, return for repair.
ERR004	Phase loss	1. Check if motor wires are broken or plugs are not properly connected; 2. Replace motor to determine if motor is faulty; 3. Motor phase sequence error, check if motor power lines are connected incorrectly; 4. Internal driver fault, return for repair.
ERR006	Position deviation	1. Check if encoder wires are broken or plugs are not properly connected; 2. Check if mechanical structure is stuck causing motor stall; 3. Motor phase sequence error, connect wires according to motor label colors in order; 4. Check if incorrect subdivision causes speed mismatch during installation.
ERR008	EEPROM	Initialize parameters and restart to see if the alarm still occurs. If the alarm persists, return to the factory for repair.
