Figure 3-5 Typical Motor Rating Plate Example

Note
♦
P0308 & P0309 are only visible if P0003 ≥ 2. Only one of the parameters are shown
depending on the settings of P0100.
♦
Changing motor parameters is not possible unless P0010=3.
♦
Ensure that the inverter is configured correctly to the motor, i.e. in the above example
delta terminal connection is for 230 V.

When operated below rated speed, the
cooling effect of fans fitted to the motor
shaft is reduced. Consequentially, most
motors require de-rating for continuous
operation at low frequencies. To ensure
that the motors are protected against
overheating under these conditions, a
PTC temperature sensor must be fitted to
the motor and connected to the inverter
control terminals as shown in Figure 3-6.
