4 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.
4.1 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 3.3.6) can be used.
The adjustment of the setpoint
values is made via the
potentiometer P1, which is
integrated in the over of the
SK 200E (Section 4.1.2). In
addition, the
minimum/maximum
frequencies 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.
