Monitoring Parameters with the Display
After using the keypad for parameter editing, it’s a
good idea to switch the inverter from Program Mode
to Monitor Mode. The PRG LED will be OFF, and the
Hertz or Ampere LED indicates the display units.
For the powerup test, monitor the motor speed
indirectly by viewing the inverter’s output frequency.
The output frequency must not be confused with base
frequency (50/60 Hz) of the motor, or the carrier
frequency (switching frequency of the inverter, in the
kHz range). The monitoring functions are in the “D”
list, located near the top left of the “Keypad
Navigation Map”on page 2-26.
