* P5-94 is able to set the DI time delay compensation to overcome the error occurred
in different speed operation.
When the servo motor moves from current position to target position, two kinds of
rotations, forward and reverse are available for selection. However, the rotation of
the E-Cam is a kind of cyclic motion movement. No matter forward or reverse
rotation is selected, the motor will reach the target position. The only difference is
that the moving distance is not the same. Using the function of forward rotation
allowable rate is able to plan the timing for forward and reverse rotation and let the
system know when the motor rotates in forward direction and when the motor
rotates in reverse direction.
* Forward rotation allowable rate: Max. allowable moving percentage when go
distance is in forward rotation. Please refer to the following explanation.

: E-Cam Current Position
: Max. forward rotation limit. In the figures below,
Counterclockwise direction is forward rotation
: Target position is within this range
(Go trip is in forward
: Target position is within this range
(Go trip is in reverse
Forward rotation allowable rate =
Go trip is in reverse rotation only.
Forward rotation allowable rate =
Max. moving degree of go trip is

Forward rotation allowable rate =
Go trip is in forward rotation only.
The E-Cam is not engaged when executing this marco
command. The E-Cam should be engaged. Otherwise, the
alighment correction cannot be executed.
