Preface
Thank you for buying AS600M series driver made by ShenZhen ALPHA Inverter
Co.,Ltd.
This series of drivers adopt the closed-loop vector control technology that features
precision speed control, high torque at low frequency and load capacity strongly. The
revised weak magnetic algorithm makes the divers have qucik reponse on high speed
area with the great load inertia, which can provide high-performance speed and
position servo function for your equipments.Its powerful function and simple operation
are easy to achieve the high precision turning,milling,spindle position control,
rigidity
tapping, thread cutting and so on.
This series of drivers have wide speed range, quick responsehigh torque at low
frequency and position tracking. They apply to most motor drive applications,
including the numerical control lathe, processing center, CNC milling machine, CNC
boring machine, and other fields such as textile industry, plastic industry, carton
packaging industry, woodworking machinery and so on.
If you have any problem that can’t be solved in operation, please contact the nearest
local agents, or contact our company directly.

    How to fix overcurrent during acceleration in Alpha AS600M?
    • L
      Lauren CunninghamAug 18, 2025
      If you are experiencing overcurrent during acceleration with your Alpha DC Drives, there are several potential causes. The acceleration time might be too short, in which case you should increase the acceleration time. The V/F curve may not be appropriate, so adjust the V/F curve setting and ensure an appropriate torque boost setting. Also, check the input power supply in case the power voltage is low. If the driver power is too small, select a driver with larger power. Finally, inspect the motor coil resistance and motor insulation to rule out a short-circuited driver output load.

    What to do if Alpha DC Drives show overcurrent during constant-speed operation?
    • M
      megankennedyAug 21, 2025
      If your Alpha DC Drives are showing overcurrent during constant-speed operation, start by checking the load for any abnormalities. It's also possible that the acceleration or deceleration time is set too short; increase these times appropriately. Verify the input power supply, as low power voltage can cause this issue. If the driver power is insufficient, select a frequency-driver with larger power. Lastly, check the motor coil resistance and the motor insulation to ensure the driver output load is not short-circuited.

    Why am I getting overcurrent during deceleration with Alpha DC Drives?
    • B
      Brandon BryantAug 23, 2025
      Experiencing overcurrent during deceleration with your Alpha DC Drives can stem from several causes. If the deceleration time is too short, increase it. A large load inertia torque may also be the cause; in this case, add appropriate brake components. Ensure that the driver power is adequate; if it's too small, select a driver with larger power. Finally, check the motor coil resistance and the motor insulation for any signs of a short-circuited driver output load.

    How to troubleshoot overvoltage during deceleration in Alpha AS600M DC Drives?
    • B
      Brittney MilesAug 26, 2025
      To troubleshoot overvoltage during deceleration in Alpha DC Drives, check the input power supply to ensure it is not abnormal and test the electrical level setting. If the deceleration time is too short, increase it appropriately. If the load inertia torque is large, add appropriate brake components. Also, check if the stalling overvoltage point is too low and raise it if necessary.

    What causes overvoltage during constant-speed operation in Alpha AS600M DC Drives?
    • N
      Nicholas GonzalezAug 28, 2025
      Overvoltage during constant-speed operation in Alpha DC Drives can be caused by several factors. An abnormal input voltage is one possibility; check the input power supply and test the electrical level setting. If the acceleration or deceleration time is too short, increase the deceleration time appropriately. A large load inertia torque may also be the cause; add appropriate brake components. Finally, the stalling overvoltage point might be too low; raise it to resolve the issue.

    Why do Alpha DC Drives experience overvoltage during acceleration?
    • T
      Teresa Young DDSAug 30, 2025
      Alpha DC Drives may experience overvoltage during acceleration due to several reasons. The input voltage might be abnormal, so check the input power supply and test the electrical level setting. Another reason might be that the acceleration time is too short; increase it appropriately. Lastly, the stalling overvoltage point could be too low, so raise it to a more suitable level.

    How to resolve a driver overloaded error in Alpha DC Drives?
    • M
      Mary LopezSep 1, 2025
      To resolve a driver overloaded error in Alpha DC Drives, consider these steps: Reduce the load and increase the acceleration time if the driver output exceeds its overload value. If the DC brake quantity is too large, reduce the DC brake current and increase the brake time. Adjust the V/F curve and torque boost if the V/F curve is not appropriate. Check the power grid voltage if it is too low. Select a driver with larger power if the load is too large. Increase the acceleration time if it is too short. Raise the current limit level if it is too low.

    What should I do if the motor is overloaded in Alpha DC Drives?
    • B
      Bradley AndersenSep 3, 2025
      If the motor is overloaded in Alpha DC Drives, there are several potential causes and solutions. If the driver output exceeds the motor overload value, reduce the load. If the V/F curve is inappropriate, adjust the V/F curve and the torque boost. Check the power grid voltage if it is too low. If an ordinary motor operates at a low speed with a large load for a long time, select a special motor. If the motor stalls or the load becomes too large suddenly, check the load.

    Why is the heat radiator overheating in my Alpha AS600M?
    • M
      Michael LopezSep 8, 2025
      If the heat radiator is overheating in your Alpha DC Drives, it could be due to several reasons. The environment temperature might be too high, so reduce it. The air duct could be blocked, so clear it. Finally, the fan might be working abnormally or damaged, so replace it if necessary.
