10 – 98 HEIDENHAIN Service Manual iTNC 530 HSCI
Feed rate 8 Height of the step for the nominal velocity value (mm/min); this entry has no effect for ramp output.
Channel 1 to 6
8 Select a signal and an axis or a spindle for the respective channel.
8 Specify the operand type (B,W,D,I,O,T,C) and the address for recording PLC operands.
8 Use the SAVED setting to “freeze” the signal last recorded for this channel. This means that the
recorded values remain available on the display. For example, you can use them to record a
reference curve for use in future measurements.
Signals The following signals can be recorded:
With the step function, the machine can accelerate with maximum force.
Improper use of the step function may cause damage to the machine or even personal injury!
Recordings made with the step function in the integrated oscilloscope are mainly used to
optimize the control loops of the machine. Optimization may only be performed by trained
specialists from machine tool builders.
The specified feed rate corresponds to the height of the step. --> As a precaution, set the feed
rate to zero!
When the internal oscilloscope is activated again, "Ramp" output is automatically selected.
To compare a SAVED signal to a newly recorded signal, both recordings should be made with the
same trigger conditions.
Otherwise, shifts on the time axis may make signal comparison difficult or impossible.
