•
The S-curve acceleration/deceleration function ensures smooth operation in applications where
linear acceleration or deceleration could cause impact due to a large change in the acceleration or
deceleration speed during start, stop, or other operation.
•
This is achieved by adding a pseudo-S-curve acceleration/deceleration value to the linear
acceleration/deceleration speed command.
For details, refer to 7-8 Soft Start on page 7-24.
•
Select the speed limit.
•
Restricts the speed as the protection during force control.
Explanation of Settings
For details, refer to 6-3 Cyclic Synchronous Torque Mode on page 6-8.
•
Set the speed limit value for force control.
•
It controls that the speed during force control does not exceed the set value.
For details, refer to 6-3 Cyclic Synchronous Torque Mode on page 6-8.
