LC3722HTC Three-phase hybrid stepping motor drive

LC3722HTC is a kind of three-phase hybrid stepping motor drive based on DSP control , it is a new generation of digital stepper motor drive made up of the advanced DSP control chip and three-phase inverter driver module combine together.The drive voltage is AC110V – 220 v, adaptive current is below 7.0 A,57-130 mm external diameter of the various types of three-phase hybrid stepping motor. The inner of drive adopts a circuit similar with servo control principle.the circuit can make the motor run smoothly, little vibration and noise.When motor is in high speed, the torque is much higher than the two and five phase hybrid stepping motors.Step positioning accuracy up to 60000 / rolls. The products are widely used in engraving machine, medium-sized nc machine, computer embroidery machine, packaging machinery and other high resolution of large and medium-sized CNC equipment.

Features:

·High performance and low price
·Equipped with 16 files of uniform angle constant torque subdivided ,the max resolution is 60000 steps/roll
·The highest response frequency up to 200 KPPS
·when step pulse stops for more than 1.5 S, coil current will be reduced
to half of the rated current automatically

·Photoelectric isolation, signal input/output
·Drive current 1.3A/phase to 7.0 A/phase ,16 files is adjustable
·Single power input, the voltage range: AC110V – 220 v

·Phase memory function (note: when stop inputting for more than 3 seconds, drive will bear motor phase in mind automatically at the time, back to electricity or WF signals from low level to high , drive will recovery motor phase automatically)

current setting

Drive working current is set by the D1 – D4 terminals, running current set switch for normal work output current (see table below)

Drive wiring/size sketch map

Note:

1, The input voltage cannot exceed ac 220V;

2, The input control signal level is 5v,current limiting resistor is required when higher than 5 v

3, Falling edge is effective when inputting pulse signal ;

4, Drive will stop working when temperature over 80 degrees , failure indicator light ALM on , until the drive temperature drops to 50 degrees, the driver needs to be on the electricity can be restored. Overheating protection with radiator, please.

5,Over current (load short out) fault indicator light ALM on, please check the motor wiring and other short out fault, it needs to electrified again to recover after ruling out.

6, No motor fault indicator ALM on, please check the motor connection, it needs to electrified again to recover after ruling out.
