10 – 102 HEIDENHAIN Service Manual iTNC 530
Output 8 Select whether the nominal speed value is to be output as a jump or a ramp.
If you select ramp output, then the programmed feed rate, k
V
factors and acceleration
values that you have specified on the machine go into effect.
If you select step output, a step will be output as nominal velocity value when you press the
axis-direction buttons in the Manual operating mode. During output, the position control
loop is open. For safety reasons the step response is only possible after entering a code
number.
Feed rate
8 Define the height of the jump for the nominal speed value (mm/min). If you have defined a
ramp as output, this field has no meaning.
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 the recording of 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 be accelerated with maximum force.
When the step function is used improperly, machine damage or even personal injury
can be caused!
Recordings made with the step function in the integrated oscilloscope are mainly used for
the optimization of control loops on the machine. The optimazation may only be
performed by trained specialists of machine tool builders.
The indicated 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.
