3.2 General operation
For a full description of standard and extended parameters, please refer to Section 6.
3.2.1 General
1. The inverter does not have a main power switch and is live when the mains supply is
connected. It waits, with the output disabled, until the RUN button is pressed or for
the presence of a digital ON signal at terminal 5 (rotate right).
2. If a BOP or an AOP is fitted and the output frequency is selected to be displayed
(P0005 = 21) the corresponding setpoint is displayed approximately every 1.0
seconds while the inverter is stopped.
3. The inverter is programmed at the factory for standard applications on Siemens four-
pole standard motors that have the same power rating as the inverters. When using
other motors it is necessary to enter the specifications from the motor's rating plate.
See figure 3-5 for details on how to read motor data.
