To enable bell–shaped acceleration/deceleration in addition to optimum
torque acceleration/declaration, set HRB, bit 0 of parameter No. 19504
to 1and the bell–shaped acceleration change time with parameter
No.1774.
In case that optimum torque acceleration/deceleration is disabled,
acceleration/deceleration for rapid traverse will be after–interpolation
acceleration/deceleration or before interpolation acceleration/deceleration.
When the command having the following restriction is commanded,
optimum torque acceleration/deceleration is disabled.
(Restriction)
Optimum torque acceleration/deceleration is disabled at the command
with the restriction ”AI high precision contour control mode or the AI
nano high precision contour control mode is automatically canceled once
and the buffering is inhibited” which is mentioned in the specification
manual for AI high precision contour control mode or the AI NANO high
precision contour control.
For example, during the following commands which includes the
M,S,T,B code, optimum torque acceleration/deceleration is disabled;
1. G00 100.M13; (G00 with M code)
2. G00 100.S1000; (G00 with S code)
3. G00 100.T01; (G00 with T code)
4. G00 100.B20; (G00 with B code)
