Description

       SEA3D420 is a microstep motor driver with uniform angle and constant torque subdivisions, voltage range is AC110~220V ( the optimal voltage is AC220V ), single power supply. It matches 3 phase hybrid stepper motors which rated current under 4.2A, external diameter 86mm~110mm, and outlets 3 or 6.

       Bipolar constant current chopper control makes the motor run smoothly with lower noise and higher stability; The increase of the voltage greatly improves the drive capability and speed. The coil current will be automatically reduced to 20%~80% ( set by STOP ) onece the pulse stops for more than 100ms, it reduces the heat of driver by 50%, reduces the heat of motor as well. Users can choose low speed high subdivision which up to 60000 steps/rev, it improves the precision, reduces the vibration and noise.

DIP Switch Setting

 

DP1

OFF: accept external pulse signal

ON: driver send 7.5KHz pulse, then the microstep should be set to be 2000-10000

DP2

OFF: pulse signal+direction signal control

ON: clockwise pulse+counter clockwise pulse control

 

Running Current Setting

1. STOP/Im is stable state current adjuster, it can be set to 20%~80% of the normal output current ( Adjusting it clockwise will increase the current and counterclockwise decrease current )

2. RUN/Im is normal running current adjuster ( please check the details as follows )

Function

Instruction

POWER

Power indicator

Power on, the green indicator normally on.

TM

Working indicator light

When the pulse frequency is low, the green indicator flashes, when the pulse frequency is high, the green indicator normally on.

O.H

Overheat indicator

The Temperature rise exceeds 70 ℃, the red indicator normally on.

O.C

Overcurrent / Low voltage indicator

The current exceeds rated value or the voltage is lower than rated value, the red indicator normally on.

Im

Phase current setting adjuster

Set the phase current, clockwise it increases, anticlockwise it dereases.

PU+

Input signal positive side

For changing the direction,input resistance is 220 Ω. Requires: low level +0V~+0.5V, high level+4V~+5V, pulse width >2.5 μs

PU-

DP2=OFF, PU is pulse signal

When the falling edge is valid, the motor moves a step as the pulse become lower, input resistance is 220Ω;. Requires: low level +0V~+0.5V, high level +4V~+5V, pulse width >2.5&μs.

DP2=ON,PU is clockwise pulse signal

DR+

Input signal positive side

For changing the direction,input resistance is 220 Ω. Requires: low level +0V~+0.5V, high level+4V~+5V, pulse width >2.5 μs

DR-

DP2=OFF, direction control signal

Pulse signal power supply should in the range of +5V~+24V, if higher than +5V needs to add a resistor.

DP2=ON, counter clockwise pulse signal

MF+

Input signal positive side

For changing the direction,input resistance is 220 Ω. Requires: low level +0V~+0.5V, high level+4V~+5V, pulse width >2.5 μs

MF-

Motor free signal

When the low electrical level is valid, it cuts off the motor current, the driver stops working and motor will be in a free state.

TM+

Origin input signal positive side

The signal is valid when the motor pass electrical origin.

TM-

Origin output signal negative side

TM+ connects resistor, TM- connects GND, the max output current is 50mA, the max voltage is 50V.

RDY+

Driver ready signal positive side

Pulse signal power supply should in the range of +5V~+24V, if higher than +5V needs to add a resistor.

RDY-

Driver ready signal negative side

It's valid when the driver is in normal state and ready for accecpting signals from controller.

Attantion

1、Please do not reverse the power supply, input voltage not more than AC230V;

2、The input control signal level is +5V, if higher than +5V, needs to add a resistor on PU-, DR-, FM- ( do not add on + sides );

3、This model of the driver uses a special control circuit, so it matches stepper motor of 6 or 8 outlets only;

4、The driver will automatically stop working when the temperature exceeds 70 degrees, the O.H indicator light normally on, temperature drops to 50 degrees it automatic recovers to work, please install radiator when it's in overheating protection;

5、When the current exceeds rated value or the voltage is lower than rated value, the O.C indicator light normally on, please check the connections and other short troubles needs to re-up power after the faults cleared, or if the power voltage is too low;

6、The PWR green indicator light normally on when the driver is powered on;

7、The TM indicator light comes on when the pulse input go crossing the zero point.
