3. HIGH–SPEED RESPONSE
FUNCTION
PROGRAMMING
(Power Mate i–H)

This function enables to specify time constant of linear acceleration/
deceleration to every block respectively. When this command is
specified, an axis is accelerated to the feedrate F by the time constant
specified by Q at first, and moves at the feedrate F. At the end of block,
an axis is decelerated by the time constant R.
As the feedrate specified by F is effective until next F command is
specified, it is not necessary to give a feedrate command at every block.
If feedrate F is not specified, F is regarded as ”0”.

CAUTION
1 The address Q and R must be set in every block. As the
address Q and R are not modal data, an axis move without
acceleration/deceleration (time constant 0) when address
Q and R is not specified.
2 The value of feedrate override (*FV0–*FV7) is read in when
the block is read from program memory. (In other words, at
the moment when the previous block starts executing) If
override is changed after the above, new value is ignored.
3 When the override cancel signals, HOVCn(G227) or
OVC(G0006#4), is turned to high, the feedrate override is
fixed at 100%. But these signals are read in also at the
moment when the block is read from program memory.
NOTE
1 Only one axis can be specified in the block of G135.3
2 G135.3 belongs to the group 01 G code.
3 An axis will stop once after this command.
4 Only feed per minute is allowed.
