FP5/GP5 Operation
Reverse Run Prohibit (n006, Reverse Oper)
A “reverse run disabled” setting does not accept a reverse run command
from the control circuit terminal or the digital operator. This setting is
used in applications where a reverse run command can cause problems.
Soft-Start Characteristics (n022, S-Curve Select)
An S-curve pattern is used to reduce shock and provide smooth transitions
during machine acceleration and deceleration.
Note: The S-curve time is the time to reach the set accel/decel rate (as determined by the accel/
decel time settings).
