General operation

For a full description of standard and extended parameters, please refer to the
Parameter List.
NOTICE
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 3-7 for details on how to read motor
data.
4. Changing motor parameters is not possible unless P0010 = 1.
5. You must set P0010 back to 0 in order to initiate a run.
