Description

SEA2D68 is a microstep motor driver with uniform angle and constant torque subdivisions, Stepper driver voltage is DC12～40V ( The optimal voltage is DC70V ), single power supply. It matches 2 phase hybrid stepper motors which rated current under 6.0A, external diameter 56mm～85mm, and outlets 6 or 8.

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 halved automatically 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 40000 steps / rev, it improves the precision, reduces the vibration and noise.

ON: Double Pulse, PU is Clockwise stepper pulse, DR is Counter Clockwise pulse signal.

OFF: Single Pulse, PU is stepper pulse signal, DR is Direction control signal.

Self detect switch ( OFF: accept external pulse signal; ON: driver internal send 7.5kHz pulse, at this moment the microstep should be set to be 2000～10000 )

Pin functions

Mark	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.
+	Input signal positive side	Pulse signal power supply should in the range of +5V～+24V, if higher than +5V, needs to add a resistor on PU-, DR-, FM- ( do not add on + sides ).
PU	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.
DR	Direction control signal	For changing the direction, input resistance is 220Ω. 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.
+V	Power +	DC24～80V ( The optimal voltage is DC70V ).
-V	Power -	DC24～80V ( The optimal voltage is DC70V ).
AC、BC	Connect to the motor	Please refer to the motor connections.
+A、-A
+B、-B

Attention

1. Please do not reverse the power supply, input voltage not more than DC80V;

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.
