The frequency inverters used in the sat-nms ACU-RMU are equipped with a Basic Operation Panel (BOP) that shows you all of the parameters set to the frequency inverter. It also is able to show you the actual values of frequency, voltage and output voltage. The following picture shows how the BOP looks like:

After start-up of the inverter the display of the BOP shows you the following values:

• If the motor is running, the display shows you the actual motor frequency and the direction (with or without a - as prefix of the shown frequency what represents the rotation-direction)
• If the motor is not running, the display is alternating between the pre- selected frequency with prefix for the direction and the actual frequency 0.00Hz.

If you like to get some other parameters, press and hold the button Fn longer than 2s. By pressing the button Fn once you can change between the following parameters:

• DC link voltage (indicated by d - units V).
• output current. (A)
• output frequency (Hz)
• output voltage (indicated by o - units V)

To return to the start-up display mode, press and hold the button Fn for longer than 2s. The following Table shows the function of the frequency-inverters buttons.

• — indicates status — The LCD displays the settings and values currently used by the converter.
• — start converter — pressing the button starts the converter. This button is disabled by default . To enable this button set P0700 = 1.
• — stop converter OFF1 — Pressing the button causes the motor to come to a standstill at the selected ramp down rate. Disabled by default , to enable set P0700 =1. OFF2 Pressing the button twice (or once long) causes the motor to coast to a standstill. This function is always enabled.
• — change direction — press this button to change the direction of rotation of the motor. Reverse is indicated by a minus (-) sign or a flashing decimal point. Disabled by default , to enable set P0700 = 1.
• — jog motor — Pressing this button while the inverter has no output causes the motor to start and run at the preset jog frequency. The motor stops when the button is released. Pressing this button when the motor is running has no effect.
• — functions — this button can be used to view additional information. It works by pressing and holding the button. It shows the following, starting from any parameter during operation:
  1. DC link voltage (indicated by d - units V).
  2. output current. (A)
  3. output frequency (Hz)
  4. output voltage (indicated by o - units V).
  5. The value selected in P0005 (If P0005 is set to show any of the above (3, 4, or 5) then this will not be shown again).

Additional presses will toggle around the above displays. Jump Function From any parameter (rXXXX or PXXXX) a short press of the Fn button will immediately jump to r0000, you can then change another parameter, if required. Upon returning to r0000, pressing the Fn button will return you to your starting point.

• — access parameters — pressing this button allows access to the parameters
• — increase value — pressing this button increases the displayed value. To change the Frequency Setpoint via the BOP set P1000 = 1.
• — decrease value — pressing this button decreases the displayed value. To change the Frequency Setpoint via the BOP set P1000 = 1.
