{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.


Information

Deactivation of the IO functions

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.

Information

Parameter P434[-01]

– Disabling the IO-C mode

If the parameter (P434[-

01]) is set to values ≠ {00} or ≠ {07}, the IO-C mode of the SK SSX-3A is barred when the

frequency inverter restarts.

Operation

Control of the Simple Setpoint Box SK SSX-3A in this mode is identical to that of the SimpleBox SK CSX-3H/ -3E
(see Section 2.2).

Control commands (enable/stop/direction of rotation) and setpoints from the box are only recognised by the
frequency inverter if it has not been enabled from other sources (e.g. digital input of the FI) (priority switching). This
also means that the drive of the source from which it was started must also be set back to Stop.
