Suppressing the 
status signals of the 
HEIDENHAIN 
supply unit
The parameter object CfgPowerStage is not required for:
 Virtual axes (MP_axisMode = Virtual)
 Axes that are for display only (MP_axisMode = Display)
 Analog axes (MP_axisHw = Analog)
The HEIDENHAIN power supply units have several status signals which lead 
to error messages on the control. MP_powStatusCheckOff is used to 
suppress the error message for each status signal. 
HEIDENHAIN does not recommend suppressing the error messages from the 
power supply units. If you are using a UE 2xx, the signals must be suppressed 
because the UE 2xx compact inverter does not provide these signals.
The handling of status signals from HEIDENHAIN power supply units, which 
are already inactive during control start-up, varies depending on 
MP_ampStatusCheckOff – bit 0.
MP_powStatusCheckOff
 Bit 0 = 0: Missing signals do not result in an error message when the drive 
is switched on. 
 Bit 0 = 1: Missing signals result in an error message when the drive is 
switched on. Signals that are not provided by the power supply unit must be 
suppressed with MP_powStatusCheckOff (bit 1 to bit 6), because non-
existent signals are always identified as errors.

Signals that change their status during operation are always identified as 
errors.
