5.2 Commissioning of the frequency inverter
The SK 2xxE inverter series can be commissioned in various ways:
a) For simple applications (e.g conveyor applications) by means of the DIP switches integrated into
the frequency inverter (internal) and the (externally accessible) potentiometers (SK 2x5E only).
In this configuration the plug-in EEPROM is not required.
b) By adaptation of parameters using software via the ParameterBox (SK CSX-3H or SK PAR-3H) or
NORD CON PC - supported software.
Here, the parameterised data is stored in the plug-in EEPROM ("memory module") As of firmware
V4.3 (available about the 3rd quarter 2011) the data is automatically saved in the internal EEPROM
if no EEPROM is plugged in.
For older firmware versions an external EEPROM must always be plugged in during operation in
order to permanently save changed parameter values.
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)).
5.2.1 Connection
After mounting the frequency inverter connection unit on the motor or the wall mounting kit, the mains and
motor cables must be connected to the relevant terminals
(PE, L1, N (/L2, L3) and U, V, W) (See sections 2.7
and 2.8).
In addition, with SK 2x5E models, a 24V control voltage supply to the frequency inverter is essential
(connection to terminals 44/40).
In principle, the frequency inverter can be operated in this configuration. (See Section 5.2.3)
NOTE
SK 2x5E:
The necessary 24V control voltage can be implemented by in integrated (SK CU4-
…-24V) or an
external (SK TU4- …-24V) optional mains unit or a comparable power source (min. 200mA)
