TIME CONST.
Address Meaning Description
Time constant for post-interpolation rapid
feed acceleration/deceleration filter
Program type M, E
Conditions After stop of movement
N4
Unit 1 msec
Setting range 0 to 455
Set the time constant for the filter that further smoothens the speed signal
waveform during rapid feed (G0) operation with shape correction off and
during rapid feed operation in manual operation mode.
The filter will be invalid if 0 is set.
Cutting-feed time constant
(First-order lag)
Program type M, E
Conditions Immediate
N5
Unit 1 msec
Setting range 0 to 5000
First-order lag time constant for cutting-feed acceleration/ deceleration
(First-order lag) (Exponential acceleration/
linear deceleration)

During external deceleration, the position loop is disconnected for the time
interval set using this parameter and, as a result, the speed becomes
zero.
