Speed
T
Time
T : Total time. it is constant irrespective of feed rate.
(Time constant is constant).
The curve corresponds to that T
1
= T/2 and T
2
= T/2 set in pa-
rameter No.1620 and 1621.

Inch machine 0.1 inch/min 0,6 to 6000 0,6 to 4800
Rotaion axis 1 deg/min 0,6 to 15000 0,6 to 12000
Set the lower limit (FL rate) of exponential acceleration/deceleration in
cutting feed for each axis.
NOTE
Except for special applications, this parameter must be set
to 0 for all axes. If a value other than 0 is specified, proper
straight lines and arcs cannot be obtained.
1624 Time constant of acceleration/deceleration in jog feed for each axis
[Data type] Word axis
[Unit of data] ms
[Valid data range] For exponential acceleration/deceleration
0 to 4000
For linear or bellshaped acceleration/deceleration after cutting feed
interpolation is applied
S When the time constant expansion function is not to be used (bit 1 of
parameter 1605 = 0)
0 to 8192
S When the time constant expansion function is to be used (bit 1 of param-
eter 1605 = 1)
Number of controlled axes Vaild data range

3 to 4 0 to 16000
5 to 8 0 to 8000
Specify the jog feed acceleration/deceleration time constant for each axis.
