4.2 Basic Operation
Refer to section 6 for a full description of each parameter.
4.2.1 General
(1)
The inverter does not have a main power switch and is therefore 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 via terminal 5 (rotate right- default)
or terminal 6 (rotate left- default) -
see parameters P051 to P055 and P356
.
(2)
If output frequency (P001 = 0) is selected as the display, the corresponding setpoint is flashed on the display approximately
every 1.5 seconds while the inverter is stopped.
(3)
The inverter is programmed at the factory for standard applications on Siemens standard motors. When using other motors it
is necessary to enter the specifications from the motor's rating plate into parameters P080 to P085
(see Figure 4.2.1)
.
Note:
Access to these parameters is not possible unless P009 = 002 or 003.
(4)
A separately-driven fan and/or a temperature sensor must be provided in the motor to protect it if the drive is operated
continuously below approx. 15 Hz drive inverter frequency
Figure 4.2.1: Typical Motor Rating Plate Example
Note:
Ensure that the inverter is configured correctly to the motor, i.e. in the above example delta terminal connection is for 220 V.
4.2.2 Initial Testing
1.
Check that all cables have been connected correctly (see
section 2 or 3
) and that all relevant product and plant/location safety
precautions have been complied with.
2.
Apply mains power to the inverter.
3.
Ensure that it is safe to start the motor. Press the RUN button on the inverter. The display will change to
5.0
and the motor shaft will
begin to turn. It will take 1 second for the inverter to ramp-up to 5 Hz.
4.
Check that the motor rotates in the direction required. Press the FORWARD / REVERSE button if necessary.
5.
Press the Stop button. The display will change to
0.0
and the motor will slow down, achieving a complete stop after 1 second.
