kit

Fastening

With screw fasteners

NOTICE

Sealing

When installing (module, cable glands, plug connectors), take care that there is a good seal, in order to prevent the entry of moisture and the danger of corrosion and short circuits. With IP66 modules (SK TI4-TU-...-C) the membrane valve (supplied) must be screwed in, in order to prevent the accumulation of condensation.

Switch off the mains.

Remove the two M25 caps on the required side of the frequency inverter (right / left).

Remove the printed circuit board (with terminal bar) from the SK TI4-TU-…. connection unit.

Install the SK TI4-TU- ... with the enclosed seal on the SK 2xxE using the 4 enclosed bolts.

Insert both of the enclosed grommets in the M25 cable glands (to protect the internal wiring between the module and the frequency inverter).

Replace the printed circuit board (See point 3) and carry out the electrical connections.

SK TI4-TU-…-C version devices: remove the top M20 cable gland (however not at the diagnostic inlet) and insert the enclosed membrane valve into this screw fitting.

Fit and screw on the SK TU4 module.

The special wiring of the M12 round plug connector enables connection of both single and double sensors, which are equipped with normal M12 system connectors in the standard sensor/actuator configuration.

With the use of M12 round plug connectors, the terminal bar connectors for the digital inputs (connection unit of the option) must not be used.

The LEDs between the plug connectors indicate the switching status of the IOs (top, from left to right DIN1, DIN3, DOUT1 / bottom, from left to right DIN2, DIN4, DOUT2).

Connection examples

The following connection examples are generally applicable for NORD IO modules. The number or type of the available IOs and their configuration on the terminal rail varies according to the module. The actual availability or the designation of the individual contacts should be obtained by reference to the description of the connections. The technical data (e.g. load capacity) must be taken into account.

Note

Broadcast mode

In "Broadcast mode, which is activated via the parameter (P162), the module can access up to 4 inverters in parallel. Therefore the frequency inverters jointly access the I/Os and evaluate the input signals according to their own parameterisation. Output signals from the frequency inverters which are sent to the common IO module are linked by a logical "OR" within the module. i.e. a digital output is set as soon as one of the four frequency inverters addresses it. In addition, the highest analog value is provided via the analog output of the IO extension.

Configuration

Configuration of the module is mainly performed via the DIP switches. The DIP switches are read after a "power on" of the module. A change to the DIP switch during operation has no effect.

The system bus must be terminated at both of its physical ends (if necessary set the "System bus termination resistor" DIP switch).

Parameterisation

Inverter: In order to establish communication between the inverter and the IOE module, the following inverter parameters must be changed.

IO extension: The module provides a selection of parameters for setting or displaying special operating values. The parameters can be changed with the aid of the NORDCON software or with a ParameterBox. Communication is only possible via an SK 54xE or SK 2xxE which is connected to the module.
