Set the rapid traverse rate when the rapid traverse override is 100% for each
axis.
The reference acceleration is calculated with this parameter and No.1773.

Specify a time constant used for acceleration/deceleration in rapid traverse.
(1)
When the parameter HRB(No.19504#0) is set to 0,
Set the time constant for linear acceleration/deceleration.
If this parameter is set to 0, parameter No.1620 is used.
(2)
When the parameter HRB(No.19504#0) is set to 1,
Bell–shaped acceleration/deceleration for rapid traverse is selected.
Set the time constant T1 for Bell–shaped acceleration/deceleration.
If this parameter is set to 0, parameter No.1620 is used.
The time constant T2 for Bell–shaped acceleration/deceleration is set to
parameter No.1774.
(3)
When the Optimum torque acceleration/deceleration is provided,
The reference acceleration is calculated with this parameter and parameter
No.1420. If this parameter is set to 0, parameter No.1620 is used for this
calculation. In case of the calculated acceleration is over 100000.0 mm/sec

,
reference acceleration is clumped 10000.0 mm/sec

. In case both this
parameter and No.1620 are set to 0, next value is applied for the reference
acceleration.

In case both this parameter and No.1620 for all axes are set to 0, Optimum
torque acceleration/deceleration is disable.
