2-PHASE STEPPING DRIVER CF20611M

2-Phase Digital Stepping Motor Driver CF20611M 

Overview: 

CF20611M 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 AC60-110V, adapter current is below 6.0A and  86-110MM 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 20,000 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 20,000  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 1.2A / phase to 6.0A / phase 16 scales adjustable  Single power input, voltage range: AC60-110V  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.)

Current Setting: 

The operating current of the drive is set by theDP1- D1-D4 terminals, which switch for normal working  output current (See the table below).

Subdivision Settings 

The drive’s subdivision is set by DP2-D1-D4 terminals. It has 16 scales. D5,6 is function set. Subdivision reference table(pulse / revolution) 

Drive Wiring and Dimension Diagram

1. Input voltage cannot exceed AC 110V. 

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.
