HEIDENHAIN TNC 430 PA/M - Integrated Oscilloscope

December 2001 Integrated Oscilloscope 6 – 457
6.23 Integrated Oscilloscope
The TNC features an integrated oscilloscope.
With this oscilloscope you can record the following characteristics in up to four
channels:
Actl. speed Actual value of the axis feed rate [mm/min].
Calculated from position encoder
Noml. speed Nominal value of the axis feed rate [mm/min]. Axis
feed rate calculated from the difference from the
nominal position values. The following error isn’t
included.
Feed rate Contouring feed rate [mm/min]
Actual pos Actual position [mm]
Noml. pos Nominal position [mm]
Lag Following error of the position controller [µm]
Position: I1 Signal 1 of the position encoder
Position: I2 Signal 2 of the position encoder
SAVED The signal last recorded is saved.
PLC The PLC operands (B, W, D, I, O, T, C) are recorded.
Enter the operands in the input field next to the PLC.
Acceleration Nominal value of the acceleration [m/s
2
]
Jerk Nominal value of the jerk [m/s
3
]
Pos. Diff. Difference between position and speed encoder
[mm]
Current Accel. Current acceleration value [m/s
2
]. Calculated from
position encoder.
Current Jerk Current jerk value [m/s
3
]. Calculated from position
encoder.
Analog axes:
Volt.analog Analog voltage = nominal velocity value [mV]
Digital axes:
V (ACT RPM) Shaft speed actual value [mm/min];
Calculated from rotary speed encoder and
standardized with MP2020
V (NOM RPM) Nominal velocity value [mm/min]: Output quantity of
the position controller
I (INT RPM) Integral-action component of the nominal current
value [A]
I nominal Nominal current value [A] that determines torque
