Speed tracking startup settings
first step:
Explanation of the principle.
When the frequency converter stops, some large motors may still be rotating at high speed due to inertia. If the frequency converter is restarted at this time, the electromotive force generated by the mechanical energy of the motor will cause the internal bus voltage of the frequency converter to rise. When the bus voltage reaches the overvoltage fault value of the frequency converter, the frequency converter will be shut down due to fault protection. At this time, if the speed tracking function of the frequency converter is turned on, the frequency converter will capture the current motor speed by calculating the motor current value and match the motor speed within the allowable frequency range, thereby smoothly controlling the motor to reach the current frequency.
Step Two:
Parameter settings.
Change the inverter start mode F02.00 to 2 to enable speed tracking, change the start delay time F02.01 to 0.5 seconds, and change the speed waiting time F02.08 to 0.5 seconds.
External terminal start/stop delay setting
first step:
Once the inverter start/stop delay time is set, the internal delay counter will be activated when the terminal is closed or opened, and it will only take effect after the set time has been reached.
Step Two:
Taking X1 forward rotation start and stop and X2 reverse rotation start and stop as an example, with a delay time of 5 seconds for each.
Set parameters F08.02=5, F08.03=5, F08.04=5, F08.05=5, and parameter F01.15=1 for external terminal startup.
Step 3:
When the forward start wire is connected, the inverter will operate after a 5-second delay. Disconnecting the inverter will not stop the machine immediately; it will also operate after a 5-second delay. The same applies to the reverse function.
Constant pressure water supply single-unit dedicated parameter settings
When the water pressure is too high, there is a risk of the water pipe bursting; when the water pressure is too low, it may cause water shortage.
Setting up a constant pressure water supply system not only saves energy and eliminates the risk of pipe bursts, but also enables continuous 24-hour monitoring of water volume and pressure, giving people peace of mind.
first step:
Prepare one frequency converter and one remote pressure gauge.
Step Two:
Connect the power cord, signal line, and ground wire of the remote pressure gauge to the inverter motherboard 10V power supply, signal AI1, and ground GND, respectively.
Step 3:
Parameter settings.
Change F12.00 to 1, and select the one-to-one constant water mode.
The target pressure value setting for F12.01 is 0.2 by default, which represents 2 pressures. It is now changed to 0.3, which represents 3 pressures.
F12.06 is the remote pressure gauge range setting. If the pressure gauge range is 1.6, change the value of F12.06 to 1.6. The default value is 1.0.
Hibernation function: Change parameter F12.02, the inverter sleep frequency value (default 30Hz), to 40Hz. The inverter wake-up pressure value (default 0.15), when changed to 0.1, means it will automatically wake up at 1 pressure. F12.04 and F12.05 are the sleep delay and wake-up delay times; both can be set to 1 second simultaneously.
Step 4:
Start the frequency converter.
When the pressure gauge feedback pressure is 0, the frequency converter will run continuously at 50Hz. As the pressure gauge pressure increases and reaches the set value, the frequency converter frequency will gradually decrease. When the frequency drops to 40Hz, the frequency converter frequency will accelerate to 0, thus entering a sleep state. When the pressure gauge target pressure drops to 1 bar, the frequency converter will rise to 50Hz again to reach the set pressure value.
