First Switch-On - Siemens 6SE2101–1AA01 Operating Manual

5.2 First Switch–On
NOTE
If the inverter is to be used with tachometer feedback or it is to be controlled via a serial interface, refer to
sections 6 and 7 respectively.
Check input power and connections (see section 4) .
(1)
(2) Switch on input power. The display should illuminate and read 00.0. It will then alternate between 00.0 and
the frequency to which the drive will ramp up when started.
(3) Set the parameters required (see 5.3) .
(4) Set the frequency set–point. Adjust the analogue set–point to 0, or set digitally to minimum frequency via
P09. (Also see section 5.3.2 for digital frequency set–point and skip mode operation.)
(5) Select parameter P00, and then press 'P'. The display should read 00.0.The display will then alternate
between 00.0 and the frequency to which the drive will ramp up when started.
(6) Switch on the inverter at the run/stop input (see section 5.1.1) . The inverter runs to the minimum frequency
set by P07, or to the digital frequency set–point (P09).
Note that if automatic boost operation has been selected (see section 5.3.2) , the inverter will measure
motor characteristics and startup will be delayed for several seconds. This only occurs at first start up
following a change (other than a change to zero) of parameter P19.
(7) Adjust the low frequency voltage boost (P01) to suit the motor. If required, automatic boost may be used
instead (see section 5.3.2) . Reset to frequency indication by selecting P00 and pressing 'P'.
(8) Adjust the motor speed to the required value as shown by the front panel indicator.
(9) To reverse the direction of rotation of the motor, apply a voltage to the FORWARD/REVERSE input via an
external switch. The front panel display and the motor should decelerate through 0 Hz and re–accelerate
to the set frequency using ramp values set by P02 and P03.
(10) To stop the motor, apply a stop signal (see section 5.1.1) or turn off the input power. The motor will run
down as defined by parameter P05 (or P11) until the display reads 00.0.
