How do I fix a rectifier module radiator overheat alarm on my Himel HAV SP Water Pump?
If your Himel Water Pump's rectifier module radiator is showing an overheat alarm, it could be due to a few reasons. The ambient temperature might be too high, so reduce the ambient temperature. Also, check for a blocked air duct and clear it if necessary. If the fan is damaged, you'll need to replace it.
Why is my Himel HAV SP drive experiencing constant-speed running overcurrent?
If your Himel Water Pump drive is experiencing constant-speed running overcurrent, it could be due to several factors. A sudden change of load can cause this, so try to reduce the sudden change of load. Also, check the acceleration/deceleration time and extend it if it's set too short. An abnormal load may also be the cause, so perform a load check. Low power grid voltage can also lead to this issue, so check the input power. Finally, the drive power might be insufficient, so consider using a drive with a larger power level.
How to fix a drive overload alarm on a Himel Water Pump?
If you're getting a drive overload alarm on your Himel Water Pump, it could be due to several reasons. The acceleration time may be too short, so try extending it. Excessive DC braking capacity can also cause this, so reduce the DC braking current and extend the braking time. An improper V/F curve can also trigger the alarm, so adjust the V/F curve and the torque boost. If the motor restarts in rotation after an instant stop, set the start mode F2.00 to speed tracking restart function. Also, check the power grid voltage, as extremely low voltage can cause this. Finally, the load may be excessive, so select a drive with a larger power.
What causes decelerated running overcurrent in a Himel HAV SP Water Pump drive?
If your Himel Water Pump drive is showing decelerated running overcurrent, it could be because the deceleration time is too short; try extending it. Another possibility is a load with potential energy or large inertia torque, in which case you should externally add a proper energy consumption braking component. Lastly, the drive power may be too small, so consider using a drive with a larger power level.
How do I troubleshoot a motor overload alarm on my Himel Water Pump?
If your Himel Water Pump shows a motor overload alarm, it could stem from several causes. An improper V/F curve may be the issue, so set the V/F curve and the torque boost correctly. Check the power grid voltage, as extremely low voltage can trigger this alarm. If the motor operates for a long time at a low speed with a large load, consider using a special motor designed for long-term, low-speed operation. Ensure the motor rated current is set correctly. Lastly, check the load, as a stalled motor or a large sudden change of load can cause this alarm.
What causes accelerated running overvoltage in a Himel HAV SP Water Pump drive?
If your Himel Water Pump drive is showing accelerated running overvoltage, it could be due to abnormal input voltage, so check the input power. The acceleration time may also be set too short, so extend the acceleration time as appropriate. If the motor restarts in rotation after an instant stop, set the start mode F2.00 to speed tracking restart function.
How to fix a 485 communication error alarm on a Himel Water Pump?
If your Himel Water Pump shows a 485 communication error alarm, it could be due to an improper baud rate setting, so set the baud rate properly. It may also be a serial port communication error, in that case press the stop key to reset, and seek for service. If the fault alarm parameter setting is improper, modify the settings of Fb.04, Fb.03 and FA.07. Finally, if the host computer doesn’t work, check whether the host computer works or not, and whether the wiring is correct.
What causes a phase loss alarm at the input side of a Himel HAV SP?
If you're getting a phase loss alarm at the input side of your Himel Water Pump, it could be due to phase loss of input R, S, and T, so check the installation wiring. Also, check the input voltage.
What causes a drive module radiator overheat alarm in a Himel Water Pump?
If your Himel Water Pump drive module radiator is overheating, it could be due to several reasons. The ambient temperature might be too high, so reduce the ambient temperature. A blocked air duct could also be the cause, so clear the air duct. If the fan is damaged, replace it. If the drive module is abnormal, seek for service.
What causes an abnormal buffer circuit in my Himel HAV SP?
If your Himel Water Pump shows an abnormal buffer circuit, it could be due to several reasons. Extremely low power grid voltage can cause this, so check the power grid voltage. A damaged thyristor may also be the cause, so replace the main circuit contactor and seek for service. If the power-on buffer resistance is damaged, replace it and seek for service. A damaged control circuit may also be the issue, so seek for service. Finally, check the input R, S, T wiring, as input phase loss can cause this.
