OPERATOR’S MANUAL
Concerning the addition of
Optimum Torque acceleration/deceleration
B-63014EN/02-9
01 02.07.29 Newly Registered
Limitations
- Linear type positioning
When Optimum torque acceleration/deceleration is enabled, linear type positioning for rapid
traverse is selected automatically in AI high precision contour control and AI nano high
precision contour control mode even if the parameter LRP, bit 1 of parameter No. 1401, is set
to 0 (nonlinear type is selected).
- Modes and conditions
Optimum torque acceleration/deceleration is enabled when AI high precision contour control
or AI nano high precision contour control mode is active and the conditions under which AI
high precision contour control and AI nano high precision contour control are satisfied.
- Target axes
Optimum torque acceleration/deceleration can be performed on axes which are selected by
parameter No.7510.
- Acceleration pattern
In the same direction move, it is necessary that the acceleration during deceleration is set 1/3
of one during acceleration at least.
Also, the acceleration pattern data must be set so that the time required for the deceleration
from the rapid traverse rate to a speed of 0 does not exceed 4000 (msec). This does not
include the acceleration change time of bell-shaped acceleration/deceleration.
If the deceleration acceleration ratio or the time required for the deceleration to a speed of 0
exceeds the above range, P/S alarm (P/S5455) will be issued at the time rapid traverse is
executed.
A slight error will occur between the specified acceleration and the actual acceleration.
- Tool center point control
Optimum torque acceleration/deceleration is disabled in tool center point control mode
(except startup and cancellation). If this occurs, the acceleration/deceleration for rapid
traverse follows the reference acceleration.
