2-Phase Digital Stepping Motor Driver
CF2068H | |||||||||||||||||
|
Overview CF2068H is a 2-phase hybrid stepping motor driver based on DSP control. It is a new generation of digital stepping motor drive which combines advanced DSP control chip and 2-phase inverter drive module. The drive’s voltage is between AC18V-80V, adapter current is below 7.2A and 57-110MM diameter of all kinds of 2-phase hybrid stepping motors. It uses a similar servo control circuit, which can make the motor running smoothly, almost no vibration and noise. When the motor is at high speed, its torque is much higher than other hybrid stepping motors. Positioning accuracy is up to 40,000 steps / turn. The product is widely used in engraving machine, medium-sized CNC machine tools, computer embroidery machine, packaging machinery and other high resolution, large and medium-sized CNC equipment.
Key Features · High performance and low price · Equipped with 16 scales constant torque moment subdivision, the maximum resolution is 40,000 steps / turn · The maximum response frequency is up to 200KPPS · When a stepping pulse stops more than 1.5S, the coil current will be automatically reduced to half of the set current · Optical isolation signal input / output · Drive current 2.0A / phase to 6.0A / phase 16 scales adjustable · Single power input, voltage range: AC18-80V · The phase memory function (Note: When the drive stops for more than 3 seconds, it will automatically memorize the motor phase then re-energizes. When the WF signal goes from low to high, the drive will automatically recover the motor phase.) | |||||||||||||||||

1. Input voltage cannot exceed AC 80V.
2. Input control signal level is 5V. When higher than 5V, it needs to connect to a current limiting resistor.
3. Input pulse signal’s falling edge is valid.
4. The fault indicator Fault light will be on when the drive’s temperature exceeds 80℃ and stops working. Until the drive’s temperature drops to 50℃, it needs to re-power to resume work. Please install a radiator to protect excessing heat.
5. When Fault light for over-current (load short-circuit) fault indicator is on, please check the motor wiring and other short-circuit faults, then Re-power the motor for recovery after cleaning faults.
6. When Fault light for no-motor fault indicator is on, please check the motor wiring, then re-power for recovery after cleaning faults.
