9. CONTROL FUNCTION
B–63123EN/01
162
This function performs rapid traverse acceleration/deceleration (or rapid
traverse bell–shaped acceleration/deceleration) at 2 ms intervals to make
servo motion smooth, thereby reducing the time required for setting after
positioning.
This function is valid for an axis for which the 2MPj parameter (bit 1 of
parameter No. 1605) is set to 1. For any axis for which the 2MPj
parameter is 1, acceleration/deceleration for rapid traverse (G00, G28,
G70, manual rapid traverse, etc.) is performed at 2 ms intervals.
D The time constant related to rapid traverse is specified in 2 ms units.
D When the rapid traverse bell–shaped acceleration/deceleration
function is used, the valid data for parameter No. 1621 ranges from 0
to 128.

WARNING
1 This function can be specified for individual axes. However,
it is recommended that the function be specified for no more
than 4 axes. If this function is specified for more than 4 axes,
other optional configurations (if any) may cause the
operability and the processing speed of the CNC to greatly
degrade, disabling normal control.
2 This function cannot be used together with the look–ahead
control function.
