12.10 Pulsing spindle speed
FUNCTION S-PULSE
Programming a pulsing spindle speed
Application
Refer to your machine manual.
Read and note the functional description of the machine
tool builder.
Follow the safety precautions.
Using the S-PULSE FUNCTION you can program a pulsing spindle
speed, when operating at a constant spindle speed.
You can define the duration of a vibration (period length) using the
P-TIME input value or a speed change in percent using the SCALE
input value. The spindle speed changes in a sinusoidal form around
the target value.
Procedure
Example
13 FUNCTION S-PULSE P-TIME10 SCALE5
Proceed as follows for the definition:
Show the soft-key row with special functions
Press the PROGRAM FUNCTIONS soft key
Press the FUNCTION SPINDLE soft key
Press the SPINDLE-PULSE soft key
Define period length P-TIME
Define speed change SCALE
The control never exceeds a programmed speed limit.
The spindle speed is maintained until the sinusoidal
curve of the S-PULSE FUNCTION falls below the
maximum speed once more.
Symbols
In the status bar the symbol indicates the condition of the pulsing
shaft speed:
