INCREMENTAL FEED
RANDOM MULTIPLICATION
(File register method)
[Function]
When "Handle 1 handle feed random multiplication/incremental feed random multiplication mode
(MPS)" signal is used, amount of feed per pulse or command signal can be multiplied by value set
to file register. Multiplication value (multiplier) is set in binary code to file register (R).
[Operation]
Multiplication 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.).
When multiplier is "500" and one pulse is given in handle feed mode, for example, 500µm of feed
motion occurs. When multiplier is "30000" and one feed command signal is given in incremental
feed mode, 30mm of feed motion occurs (time constant for feed motion is equal to time constant for
rapid traverse or step).
(Note 1) Change of multiplication setting during feed motion is ignored.
(Note 2) Since considerably large multiplication can be used, the signal should be used carefully.

HANDLE 3 HANDLE FEED
RANDOM MULTIPLICATION
(File register method)
[Function]
When the random multiplication setting method (MPS) is selected for the handle feed multiplication,
a random multiplication can be designated separately from the multiplication using the normal code
method. The multiplication value is set as a binary in the file register (R).
The random multiplication for handle 2 and handle 3 is designated here.
[Operation]
The amount moved when one pulse is sent with handle 2 or handle 3 is the rate following this feed
multiplication. For example, if the multiplier is set as "500", the axis will move 500µm when one
pulse is fed with the handle mode. (The time constant for movement is the cutting feed time
constant or stop.)
(Note 1) Change of multiplication setting during feed motion is ignored.
(Note 2) Since considerably large multiplication can be used, the signal should be used carefully.
