4.2 Starting up the device

The variable frequency drive can be commissioned in various ways:
a) For simple applications (e.g conveyor applications) by means of the DIP switches (S1) integrated
in the variable frequency drive (internal) and the externally accessible potentiometers (SK 2x5E
only).
The plug-in EEPROM is not required in this configuration.
b) By changing parameters with the control and parameterization unit (SK CSX-3H or SK PAR-3H)
or the NORD CON PC-supported software.
The changes to the parameters in the plug-in EEPROM (memory module) are stored when doing
this. Data is automatically saved in the internal EEPROM if no EEPROM is plugged in as of
firmware V1.3 .
Data is generally stored in the internal EEPROM as of firmware V1.4 R2 . Data is stored in parallel
on the external EEPROM.
For older firmware versions an external EEPROM must always be plugged in during operation in
order to save changed parameter values permanently.

Information
Presetting of physical I/O and I/O bits
For commissioning standard applications, a limited number of the variable frequency drive inputs and outputs
(physical and I/O bits) have predefined functions. These settings may need to be changed (parameters (P420),
(P434), (P480), (P481)).

4.2.1 Connection
In order to provide basic operational capability, connect the power and motor lines to the relevant
terminals after the device is mounted on the motor or the wall mounting kit (

Section 2.3.2
"Electrical connection of power unit").

SK 2x5E: It is also essential for the device to be provided with a 24 V DC control voltage.
Information
Control voltage SK 2x5E:
The required 24 V control voltage can be implemented by means of an integrated (SK CU4-24V-…) or external
(SK TU4-24V-…) optional power module or a comparable 24 V DC power source (

Section 2.3.3 "Electrical
connection of the control unit").
