10.1

Range Overrun by the Setpoint Value

The range for the setpoint values is limited to +/-100%. As soon as a value outside
of this interval is input, then this value is not accepted and is set instead at +100%
(for overruns) or at -100% (for underruns). If the mailbox is enabled, a diagnostic
message is additionally generated.
10.2

Range Overrun by the Current Controller

The command variable for the current controller is limited to +/-20000
(corresponds to +/- 2 A). As soon as a value outside of this interval is input, this
value is not accepted and the control variable is set to +20000 (for overruns)
and -20000 (for underruns). The LEDs for "Status channel A" and "Status channel
B" light up red, and the status bits READY and ON_TARGET are set to "0". If
the mailbox is enabled, a diagnostic message is additionally generated.
This error can occur as soon as the target current and the dither current overrun or
underrun a value of +/- 2 A.
10.3

Interference at the Internal Data Bus

The "Initialization" LED flashes red as soon as interference occurs at the internal
data bus.
10.4

Changing the Configuration

As soon as the process data width of the I/O module is changed, a current of 0 mA
is output until the internal data bus is reset and restarted.
