5 Commissioning, SK 200E
The SK 200E inverter series can be commissioned in various ways:
a) By means of the (internal) DIP switches and the (externally accessible) potentiometer, the SK 200E
can be configured for simple conveyor applications. Various LEDs are provided for diagnostic
purposes. In this case, no additional options are required; the FI only needs to be supplied with
mains voltage and a 24V control voltage. For control (enable regulator, fixed frequencies, setpoint
values), up to 4 digital inputs and 2 potentiometers are available.
In this configuration the plug-in EEPROM is not required.
b) A convenient and comprehensive solution is provided by commissioning with software support.
Here, a PC with an RS232/458 interface or a SimpleBox/ParameterBox may be used. The
connection to the SK 200E is made via the RJ12 socket on the top. A suitable cable for connection
to a PC is available.
Here, the parameterised data is stored in the plug-in EEPROM. This must therefore always remain
plugged in during operation.
c) The motor data for the SK 200E is always pre-set to the standard values of a motor with the same
power as the frequency inverter.
ATTENTION
DANGER TO LIFE!
The frequency inverter is not equipped with a line main switch and is therefore always live when
connected to the power supply. Live voltages may therefore be connected to a connected motor
at standstill.
NOTE
For commissioning standard applications, a limited number of the frequency inverter inputs and
outputs (physical and I/O bits) have predefined functions. These settings may need to be
changed (Parameters (P420), (P434), (P480), (P481)).
5.1 Minimal configuration without options
For minimum effort for the commissioning and control, the SK 200E can be operated in its condition as
delivered. All that is needed is to provide the FI with mains voltage and a 24V control voltage. This can be
provided by the operator of the machine, or an optional module
(SK CU4-24V-xxx-B, Section 3.4.1) can be used.
The adjustment of the setpoint values is
made via the potentiometer P1, which is
integrated in the cover of the SK 200E
(Section 5.1.3). In addition, the frequency
ramps can be adjusted with P2.
Enabling of the regulator is carried out with
the switch S1.
The PTC input must be bypassed, if a
motor with PTC is not available.
