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 set to 1.

7117 Allowable number of pulses that can be accumulated during manual handle feed
[Data type] 2Word
[Unit of data] Pulses
[Valid data range] 0 to 99999999
If manual handle feed is specified such that the rapid traverse rate will be
exceeded momentarily, those pulses received from the manual pulse
generator that exceed the rapid traverse rate are accumulated rather than
canceled. This parameter sets the maximum number of pulses which can
be accumulated in such a case.
NOTE
1 If the specification of manual handle feed is such that the
rapid traverse rate will be exceeded, for example, when the
manual pulse generator is rotated at high speed with a large
magnification such as 100, the axial feedrate is clamped
at the rapid traverse rate and those pulses received from the
manual pulse generator that exceed the rapid traverse rate
are ignored. In such a case, therefore, the scale on the
manual pulse generator may differ from the actual amount
of travel. If such a difference is not acceptable, this
parameter can be set to temporarily accumulate the excess
pulses in the CNC, rather than ignoring them, up to the
specified maximum (pulses in excess of the set maximum
are ignored). The accumulated pulses are output and
converted to a move command once the feedrate falls below
the rapid traverse rate by reducing the rotational speed of
the manual pulse generator or stopping its rotation
altogether. Note, however, that if the maximum number of
pulses to be accumulated is too large, stopping the rotation
of the manual pulse generator does not stop feeding until the
tool moves by an amount corresponding to the pulses
accumulated in the CNC.
2 This parameter is valid when bit 4 (HP) of parameter No.
7100 is set to 0.
