2. External Terminal Control for Forward/Reverse Rotation and PWM Frequency Control

2.1 Forward/Reverse Rotation Control via External Terminals

To achieve forward/reverse rotation control via external terminals, connect the relevant control signals to the designated terminals on the inverter.

• Terminal Configuration:
  • SW1-SW5 (Control Circuit Terminals 4-8): These terminals can be configured to control forward/reverse rotation, start/stop, and other functions.
  • Configuration Steps:
    1. Stop the inverter.
    2. Enter the function setting mode by pressing the MODE button four times.
    3. Navigate to parameters P036-P040 using the ▲/▼ buttons.
    4. Set the desired function (e.g., forward/reverse, start/stop) to the corresponding terminal using the ▲/▼ buttons.
    5. Press the SET button to save the settings.

2.2 PWM (Pulse) Frequency Control

To control the inverter’s output frequency via PWM signals, follow these steps:

• Terminal Configuration:
  • Terminal 7 (SW4) and Terminal 8: These terminals are used to receive PWM frequency control signals.
  • Configuration Steps:
    1. Stop the inverter.
    2. Enter the function setting mode by pressing the MODE button four times.
    3. Navigate to parameter P087 using the ▲/▼ buttons.
    4. Set the value to “1” to enable PWM frequency control.
    5. Press the SET button to save the setting.
    6. Connect the PWM signal source to terminals 7 and 8 according to the wiring diagram provided in the manual.
• Additional Settings:
  • P088: Sets the number of PWM cycles to average for frequency calculation.
  • P089: Sets the PWM signal period.

By following this guide, users can effectively utilize the Panasonic Inverter VF200 series, leveraging its advanced features and flexible control options to meet various industrial automation needs.
