NORDAC Control and Parameter Boxes
6Subject to technical alterations BU 0040 GB-1611
1 General information
NORDAC control and parameter boxes enable parameterisation, control and display of the operating parameters
of the inverter series NORDAC SK 200E, SK 300E, SK 500E, SK 700E, SK 750E and vector mc.
Various versions of the control and parameter boxes are available. The box to be used with a particular inverter
series can be obtained by reference to the overview tables in Sections 2.5.2, 3.1.2 and 3.2.1.
1. For service and commissioning directly on the system the handheld versions of the parameter boxes
(SK PAR-2H, SK PAR-3H and SK CSX-3H) are recommended. These handheld units can be used for
parameterisation and display.
2. The built-in versions of the parameter boxes (SK PAR-2E, SK PAR-3E and SK CSX-3E), for
installation in a control panel enable control and monitoring of up to 5 frequency inverters (SK CSX-… 1
frequency inverters) in a control cabinet.
3. The Simple Setpoint Box SK SSX-3A is primarily intended to control SK 200E series frequency inverters
and can be sued both as a handheld unit and a wall-mounted unit.
4. The SK POT1-1 control box is a simple manual control unit for the control of NORDAC frequency
inverters with an enabling signal and setpoint. The control box can also be used as a wall-mounted unit.
The ParameterBox (SK PAR-xx) has a storage capacity which can store the complete data records for up to 5
inverters.
In order to archive the data, the ParameterBox SK PAR-2x can be connected to a PC via an interface converter
(SK IC1-232/485). In order to connect the SK PAR-3H, only a common USB connection cable (USB2.0
connection cable, A-series plug to B-series plug) is required. The NORD CON software necessary for this can be
downloaded free of charge from the Getriebebau NORD internet page http://www.nord.com.
It is also possible to transfer data from the PC to the ParameterBox. For this, a previously saved or created data
set is required (see Section 2.2.3). This is then recognised by the NORD CON Software.
WARNING
The SK PAR-3H ParameterBox must never be connected simultaneously to the frequency
inverter and the PC, as otherwise this may cause damage, especially to the PC.
WARNING
Installation must be carried out by qualified personnel only, paying particular attention to safety
and warning instructions.
Installation or removal of modules or electrical connections must only be carried out when no
voltage is present. For detailed information, please refer to the relevant frequency inverter
manual.

higher voltage (e.g. 24VDC from SK 200E), the cable can be
considerably longer.
2.1.4.2 ParameterBox Version SK PAR-3E– Built-in Version
The SK CSX-3H ParameterBox is a compact control device
for installation in a control panel and direct connection to the
frequency inverter via the RJ12 diagnostic socket. A normal
RJ12 -patch cable ("Modular cable RJ12 (6/6) - RJ12 (6/6),
1:1 assignment") with a length of up to 3m can be used for
connection.
If the ParameterBox is supplied from a power source with a
higher voltage (e.g. 24VDC from SK 200E), the cable can be
considerably longer.

2.1.4.3 Mechanical installation in a control panel
For installation in the control cabinet door or the control panel, a cut-out of 109mm x 64mm (tolerance +/- 1mm)
must be made. The sealed unit must be inserted in the pre-processed cabinet panel. For attachment to the inside
of the control panel, 6 threaded pins (M4 x 16 mm) (approx. 7 mm projection in installed condition) and the
corresponding nuts are provided. The ParameterBox is now mounted securely on the control cabinet door and has
maximum protection class IP54 on the front side, if mounted correctly.
Electrical connection of the SK CSX-3E or SK PAR-3E parameterisation boxes is made via the RJ12 socket which
is accessible from the rear. The precise assignment of the terminals can be seen in the following section.

2.1.4.4 Electrical Connection SK …-3E
The parameter boxes SK CSX-3E and SK PAR-3E are only
connected to a frequency inverter via the RJ12 socket. This
connection also provides the power supply to the box.
A termination resistor (220Ω) for the RS485 bus system is
integrated into the module. Therefore the ParameterBox should
only be connected as the first or last participant.
In contrast to the handheld version SK PAR-3H, connection of
the SK PAR-3E ParameterBox to a PC is not possible.
Connection to the particular frequency inverter is made via the
RJ12 connection sockets on the device. The SimpleBox
SK CSX-3E can only communicate with frequency inverters.
The contact assignment of the RJ-12 connection on the parameter box is as follows:

2.2 Functions of the Parameter Boxes
2.2.1 SimpleBox
2.2.1.1 Display
After connection of the SimpleBox and switching on the mains voltage (or the 24V DC control voltage) of the
frequency inverter, communication between the frequency inverter and the SimpleBox commences automatically.
After brief illumination of all he display segments and diodes of the box a
bus scan is carried out while the middle bars of the display (4-digit, 7-
segment display) may flash rapidly.
If the bus scan is completed successfully, the frequency inverter power
appears briefly in the display (e.g.: 0.37 = 0.37 KW). This step is skipped if
the SimpleBox is connected to a frequency inverter which is already in
operation.
The horizontal bars which then appear in the display indicate that the
frequency inverter is ready for operation.
If a jog frequency value is pre-set in parameter P113, or a minimum
frequency is pre-set in P104, the display flashes with this initial value.
If the frequency inverter is enabled, the display changes automatically to the operating value selected in parameter
>Selection Display value< P001 (factory setting = current frequency).
The actual parameter set is shown by the 2 LEDs next to the display on the left in binary code.
After the frequency inverter is switched off, an "OFF" appears briefly in the
display before the display is completely switched off.
"OFF" is also shown in the display if the SimpleBox is operated via an
external 24V control voltage, although the power supply (230V or 400V) is
inactive.
In this state, almost unrestricted parameterisation of the inverter (no measurement of motor resistance or
parameter identification is possible (P208 / P220)) can be carried out as described in the following section.
However, control (enabling) is not possible due to the lack of the power supply.
NOTE
The digital frequency setpoint is factory set to 0Hz. To check whether the motor is working, a
frequency setpoint must be entered with the or keys or a jog frequency via the respective
parameter >Jog frequency< (P113).
Settings should only be implemented by qualified personnel, strictly in accordance with the
warning and safety information.
ATTENTION: The motor may start immediately after pressing the START key !

2.2.1.2 Operation
Switching on the frequency inverter. The frequency inverter is now enabled with the set jog frequency
(P113). A preset minimum frequency (P104) may at least be provided. Parameter >Interface< P509 and
P510 must = 0.
Switching off the frequency inverter. The output frequency is reduced to the absolute minimum
frequency (P505) and the frequency inverter shuts down.
