3.1.3.2 Operating mode IO-C (Control mode via DI1/DO1 of the SK 2xxE)
In the operating mode IO-C, communication is via digital input "1" and digital output "1" of the frequency inverter.
Here, all the features provided by the SimpleBox SK CSX-3H/ -3E (Section 2.2) are also available.
Field of use
In this operating mode, the box can communicate with SK 2xxE series frequency inverters with firmware version V
1.3 or higher (see parameter (P707[-01])).
Functions
In this operating mode the functions
• Parameterisation
• Control
• Display of operating values
are available without restriction and correspond to those of the SimpleBox SK CSX-3H/ -3E. For technical reasons,
the display and the key reaction times are somewhat increased.
Connections
Connection to the horizontal terminal bar is by means of a
4-wire cable.
Settings on the frequency inverter
Name Parameter number Value Notes
Function, digital output 1 P434 [-01] {00} or {07}* Setting {07} corresponds to the default value
* Other settings are not permissible and result in the loss of communication between the Simple Setpoint Box and the frequency inverter in IO-C mode.
NOTE
In "IO-C" mode, the parameterised functions of the IOs "Digital Input 1 (parameter (P420[-01]))
and "Digital Output 1" (parameter (P434[-01])) are deactivated. The condition for this is that
Digital Output 1 is parameterised either to "No function" {00} or the default setting "Fault" {07}.
The DIP switch S1: 3 … 5 of the frequency inverter ("BUS" / "IO") must be left in the factory
setting ("OFF" or"0") in order to prevent communication faults on the frequency inverter.
