Irinos Measurement System
This opcode allows reading the error status of each measurement channel. Further more for incremental channels, the reference index status bit 'Refmark' can be read out. It is set, if the reference index is enabled and crossed for the first time.
Overview
Opcode: 0x38
Name: opcRHS
Function: Read hardware status
Parameter type: Binary
DLL-Function
The hardware status can be readout continuously via MSC_SetupStaticChannel and MSC_ReadStatic. This is the preferred way.
Alternatively it can be readout via MSC_WriteCommand.

PwrOvld
Error: A power supply overload of the incremental encoder(s) has been detected.
Refmark
The reference index has been crossed.
Vector
Error: The signal vector, which has been calculated from the cosine- and sine-signal, is too small. (Can only occur with 1Vpp incremental encoders.)
GComp
Error: The gain-control has reached its limit. (Can only occur with 1Vpp incremental encoders.)
OComp
Error: The offset-control has reached its limit. (Can only occur with 1Vpp incremental encoders.)
AmpErr
Error: One or both AD-converters for the measurement of the sine-/cosine-signal is/are overdriven. (Can only occur with 1Vpp incremental encoders.)
Fast
Error: The input frequency is too high.

Comments
The hardware status of the measurement channels should be checked regularly in order to verify the validity of the measurement values. Further details can be found in the users manual.
