What to do if my MacroAir Technologies Diamond HVLS shows an overcurrent problem?

  Kelly BrownAug 1, 2025
  If your MacroAir Technologies Fan is showing an overcurrent error, it could be due to several reasons: * A short circuit or grounding problem in the motor cables. Inspect the motor cables and remove any short circuits. * The load being too heavy. Measure the current flowing into the motor. If it exceeds the drive's rated current, consider replacing it with a larger capacity unit. Also, check for sudden fluctuations in the current level and reduce the load to avoid these changes, or switch to a larger drive. * The motor cable being too long. In this case, using a larger drive may resolve the issue.

What to do if my MacroAir Technologies Diamond HVLS Fan displays an overvoltage error?

  If your MacroAir Technologies Fan shows an overvoltage error, it could be due to: * Deceleration time being too short, causing regenerative energy to flow from the motor into the drive. Increase the deceleration time, install a braking resistor or a dynamic braking resistor unit, or enable stall prevention during deceleration. * Fast acceleration time causing the motor to overshoot the speed reference. Check if sudden drive acceleration triggers the overvoltage alarm. Increase the acceleration time or use longer S-curve acceleration and deceleration times. * Excessive braking load. Reduce the braking torque, use a braking option, or lengthen deceleration time. * Drive input power voltage being too high. Check the voltage and lower it within the limits specified.

What to do if my MacroAir Technologies Diamond HVLS Fan shows a DC Bus Undervoltage error?
- O

  If your MacroAir Technologies Fan is experiencing a DC Bus Undervoltage issue, possible causes include: * Input power phase loss. The main circuit drive input power may be wired incorrectly; correct the wiring. * Loose wiring at one of the drive input power terminals. Ensure all terminals are tightened properly, applying the specified torque. * Voltage problems from the drive input power. Check the voltage and correct it to be within the specified range. * Power interruption. Correct the drive input power. * An undersized drive input power transformer causing voltage drops after power is switched on. Check the capacity of the transformer.

Why is my MacroAir Technologies Fan motor overloading?
- C
  Christopher WalkerAug 14, 2025
  If your MacroAir Technologies Fan is experiencing motor overload, the issue might be due to: * The load being too heavy. Try reducing the load. * The drive being overloaded at low speeds. Reduce the load, increase the speed, or use a motor specifically designed to operate with the drive. Alternatively, increase the motor capacity. * Multiple motors running off the same drive. Disable the Motor Protection function and install a thermal relay to each motor.
