4.4 PLC Output Signals (Data Type: R***)
Cont. Signal name
A Manual feedrate B
[Function] [Operation]
Designate the manual feedrate for the axis selected with the "Manual feedrate B valid" signal.
[Caution]
(1) The speed designated with this register is valid for the manual feedrate of an axis for which the "Manual feedrate B
valid" signal is valid.
(2) Cutting override and manual override are invalid for this register's speed.
(3) This register is not related to the dry run speed.
(4) A binary value is directly set for this register. The setting unit is 0.01 mm/min (°/min).
(5) This signal is a register common for all axes.

(1) Manual feedrate B valid (FBEn: Y940 to Y947)
Cont. Signal name
1st handle/incremental feed magnifica-
A
tion
[Function]
By selecting the handle/incremental feed magnification method (MPS), an arbitrary magnification can be designated
separately from magnification set by regular code method. The numerical value specified by the magnification is set in the
file register (R) in binary.
When the "Handle/incremental feed magnification method selection" signal (MPS) is ON, this magnification is applied for
the hand pulse from handy terminal.
[Operation]
Magnification is applied to amount of feed per pulse in handle feed mode (output from manual pulse generator), or to
amount of feed per signal in incremental feed mode (+J1, -J1, etc.).
For example, when the magnification is set to "500" and one pulse is given in handle feed mode, 500 μm of feed motion
occurs. (Time constant for feed motion is equal to time constant for cutting feed or step.)
When the magnification is set to "30000" and once the feed axis selection signal is turned ON in incremental feed mode,
30 mm of feed motion occurs. (Time constant for feed motion is equal to time constant for rapid traverse.)
Note
(1) Changing magnification during feed motion is invalid.
(2) Considerably large magnification can be set in the arbitrary magnification setting method. Be especially careful when
setting the magnification.
