CAUTION
The digital frequency setpoint has been set at 5.00 Hz in the factory. This means that, it is not necessary to enter a frequency setpoint via the Δ button or parameter P005 in order to test that the motor turns following a RUN command.
All settings must only be entered by qualified personnel, paying particular attention to the safety precautions and warnings.
The parameter settings required can be entered using the three parameterisation buttons (P, Δ and ∇) on the front panel of the inverter. The parameter numbers and values are indicated on the four digit LED display.
