Analog output
Start up the DMP module for the analog setpoint with the following machine data:
MD10362 $MN_HW_ASSIGN_NUM_INPUTS
Interrupts
Record the alarm texts in the corresponding language-specific text files.
GUD
Set up the "ANALOG_AXIS_VOLTAGE" GUD for monitoring the voltage output if required.
Analog axis
Declare the axis as an analog axis with the following machine data and set the axial machine
data for the setpoint output and actual value input for the analog axis.
MD63530 $MA_ANALOG_AXIS
4.3 Example of how to configure an analog axis
One of the axes on the following machine is to be controlled by an analog drive.
• Channel 1: Machine axes AX1, AX2, AX3
• Channel 2: Machine axes AX4, AX5
• Axes 1-4 are digital axes, drive 5 is the NCU terminal block.
• Axis AX5 must be operated as an analog axis. Analog value must be available on DMP
• The direct measuring system of digital drive 3 is used as the actual value input.
• The maximum motor speed is 3000 rev/min.
• The maximum motor speed is reached at +/- 8 V.
The machine data for the DMP module, setpoint output and actual value input need to be set
as follows:
Axis-specific machine data for axis 5
63530 $MA_ANALOG_AXIS = 2
