996 HEIDENHAIN Technical Manual iTNC 530 HSCI
Operating mode:
Select the desired setting or choose the circular interpolation test
• YT: Chronological depiction of the channels
• XY: X/Y graph of two channels
• CIRC: Circular interpolation test
Sample time:
Set the time interval for recording the signals.
Possible entries: 0.6 ms, 1.8 ms and 3.6 ms
4096 samples are stored. The signals are therefore stored for the following
duration:
• 0.6 ms ⋅ 4096 = 2.4576 s
• 1.8 ms ⋅ 4096 = 7.3728 s
• 3.6 ms ⋅ 4096 = 14.7456 s
Output:
Select whether the nominal speed value is to be issued as a step or ramp.
• If you select ramp output, then the programmed feed rate, k
V
factors, and
acceleration values that you have specified with machine parameters 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. A step can be output only
if code number 688379 or 807667 has been entered.
Feed rate:
Enter the height of the step for the nominal velocity value (in mm/min). This
entry has no effect for ramp output.
Channel 1 to channel 6:
Assign the channels of the recorded signals to the respective axes.
Trigger:
Define the type of recording.
You have the following possibilities:
• Free run: The recording is started and ended by soft key. When you press
the STOP soft key, the last 4096 events are saved.
• Single shot: When you press the START soft key, the next 4096 events
are saved.
• Channel 1 to channel 6: Recording begins as soon as the trigger threshold
for the set channel is crossed.
