As shown below, executing command in the form of an S curve at the
transitional points of acceleration or deceleration can make the
operation smoother.
Please set S operation time at SEt-21. The setting
range is 0 to 5000 ms and the default value is 0.
Assuming that the time required to execute the initial speed command
is 10 seconds, the total time required to execute the speed command
after setting acceleration/deceleration time will be 10 s
deceleration time. And the total time required to execute speed
command after setting the S-curve operation time is 10 s
deceleration time + S-curve operation time.
ATTENTION
S operation alone cannot be used without setting
acceleration/deceleration time. To use S operation, please set
acceleration/deceleration time that corresponds to the user’s
situation.
What is different from CSDP is that 0 should be set at SEt-21
not to use the S operation. Setting other values besides 0
enables S operation.
