No.1621: Time constant used for bell–shaped acceleration/deceleration (T2) in rapid
traverse for each axis is set.
No.1774: Time constant used for bell–shaped acceleration/deceleration (T2) in rapid
traverse for each axis during AICC, AI-NANO-CC, HPCC, AI-HPCC, AI-
NANO-HPCC and 5-axis machining function modes is set.
When 0 is set in this parameter, parameter No.1621 becomes effective.
When the value over the above range is set, the value is clamped by the maximum
value according to the data range of the above table.
NOTE
1. Parameter No.1774 is not effective in the normal operation, APC and
AI-APC. Parameter No.1621 is effective in these modes.
2. The following option and parameter are necessary to execute bell-
shaped acceleration/deceleration:
Normal operation, APC :
Rapid traverse bell-shaped Acc/Dec option
AI-APC :
Rapid traverse bell-shaped Acc/Dec option
and Parameter RBL (No.1603#6) = 1
AICC and AI-NANO-CC :
Parameter RBL (No.1603#6)=1
AI-HPCC, AI-NANO-HPCC and 5-axis machining function modes :
Parameter HRB (No.19504#0)=1
3. When the acceleration/deceleration before interpolation is selected for
rapid traverse during AI-HPCC, AI-NANO-HPCC and 5-axis
machining function modes, the parameter No.1621, No.1774 of the
standard axis, which is decided by the parameter No.1031, is
effective. (In this case, it is not possible to set for each axis.)
