10 Diagnostics
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.

Interference at the Local Bus

The "Initialization" LED flashes red as soon as interference occurs at the local
bus.
