Allowable number of pulses that can be accumulated during manual handle
feed
[Input type] Parameter input
[Data type] 2-word path
[Unit of data] Pulse
[Valid data range] 0 to 999999999
This parameter sets the number of pulses from the manual pulse
generator that exceed the rapid traverse rate and can be accumulated
without being discarded if manual handle feed faster than the rapid
traverse rate is specified.
0:
The feedrate is clamped to the rapid traverse rate. Those handle
pulses that exceed the rapid traverse rate are ignored. (The scale
reading of the manual pulse generator may not match the travel
distance.)
Other than 0:
The feedrate is clamped to the rapid traverse rate. However,
those handle pulses that exceed the rapid traverse rate are not
ignored. In connection with the manual handle feed travel
distance selection signals MP1 and MP2 <G019#4, #5>, the
incremental feed amount is determined as described below.
(Even if the rotation of the manual pulse generator is stopped, the
tool stops after moving by the number of pulses accumulated in
the CNC.)
Let m be the magnification based on MP1 and MP2 <G019#4, #5>,
and let n be the value set in parameter No. 7117. Then, the manual
handle increment feed amount is:
When n < m:
Clamped to the value set in parameter No. 7117.
When n ≥ m:
Clamped to a multiple of the selected magnification.
12350 Manual handle feed magnification m in each axis
[Input type] Parameter input
[Data type] Word axis
[Valid data range] 0 to 2000
For each axis, this parameter sets the magnification m when manual
handle feed movement selection signals MP1 and MP2 are set to 0 and
1.
NOTE
When no value is set for this parameter, use
parameter No. 7113.
