Cloudray CL284 110V-60HZ Small_Water_Chiller Brand 5200

Q1: How was the motor's life time?                                              

A: The key factor effect motor’s life time is two bearings inside the motor. Normally, the standard bearing’s life time is about 6000 hours long time continuous working.

Q2: What’s the advantage of integrated stepper motor?                                           

A: Integrated Motor is meaning a stepper motor integrated a stepper driver, sometime Integrated an encoder also. There are much of advantage of integrated motor when comparing with motor & driver are separately, but separated motor and driver have their advantage too.

Q3: What is the signal current of the closed-loop driver?                           

Normally, the signal current is about 10mA.

Q4: How to calculate the speed according to frequency(PPS)?                                        

A: Simply, we have provided a formula: v=f/n
v: motor speed(rps) f: frequency(pps)
n: number of micro step, you can find it on stepper driver.
eg: When stepper motor driver receiving frequency 4000pps from controller, and mirco step setting on the driver is: 2000, the speed of motor is: v=4000/2000=20rps=1200rpm

Q5: Does the closed-loop driver have a position error alarm output?                                  

Yes, closed-loop stepper driver has position error alarm output, you can set the value on debug software.

Q6: Does the closed-loop driver have pulse compensation?                          

Yes, it has pulse compensation function, but the compensation is limited.
