9. MANUAL HANDLE FEED
B–63443EN/02
PMC INTERFACE
159
HPF When a manual handle feed exceeding the rapid traverse rate is issued,
0: The rate is clamped at the rapid traverse rate, and the handle pulses
corresponding to the excess are ignored. (The graduations of the
manual pulse generator may not agree with the distance the machine
has traveled.)
1: The rate is clamped at the rapid traverse rate, and the handle pulses
corresponding to the excess are not ignored, but stored in the CNC. (If
the rotation of the manual pulse generator is stopped, the machine
moves by the distance corresponding to the pulses preserved in the
CNC, then stops.)
7110 Number of manual pulse generators used
[Data type] Byte
[Valid data range] 1 or 2
This parameter sets the number of manual pulse generators.
7113 Manual handle feed magnification m
[Data type] Word
[Unit of data] One time
[Valid data range] 1 to 127
This parameter sets the magnification when manual handle feed
movement selection signal MP2 is on.
7114 Manual handle feed magnification n
[Data type] Word
[Unit of data] One time
[Valid data range] 1 to 1000
This parameter sets the magnification when manual handle feed
movement selection signals MP1 and MP2 are “1”.
WARNING
Rotating the handle quickly with a large magnification such
as x100 moves the tool too fast or the tool may not stop
immediately after the handle is no longer rotated or the
distance the tool moves may not match the graduations on
the manual pulse generator. The feedrate is clamped at the
rapid traverse rate.
CAUTION
Rotate the manual pulse generator at a rate of five rotations
per second or lower.
