shape
S-curve This feature enables to set asymmetrical shape.
Triangular drive prevention
During S-shaped acceleration/deceleration drive, INDEX drive may end
function
before the maximum speed is reached.
In this event, triangular drive can be automatically avoided.

External signal output
External signals such as hand pulser signals that are input to the EA and
EB signals can be output as CWP and CCWP signals.

Drive function JOG drive
Pulses are constantly output until the specified pulses.
SCAN drive
Pulses are continuously output until a stop command is detected.
INDEX drive
Pulses are output until the specified relative or absolute address is
reached.
ORIGIN drive
The specified drive processes are performed.
This drive is finished when the ORG signal specified edge is detected.
2-axis linear interpolation
Linear interpolation is performed toward the specified coordinates from
・
drive
the current coordinates.
Driving type is selected from INDEX drive or SCAN drive.
・
Positional errors for the specified straight line are
0.5 LSB.
・
±
The absolute and relative addresses that can be specified for
・
coordinates range from -2,147,483,647 to +2,147,483,647 32 bits .

2-axis circular
Circular interpolation is performed toward the specified coordinates
・
interpolation drive
from the current coordinates on the circular curve specified by the
center-point or passing-point coordinates.
Driving type is selected from INDEX drive or SCAN drive.
・
Max speed is 5 MHz.
・
Positional errors for the specified circuit curve are
1 LSB.

Linear speed constant
Control is performed to keep the synthesized speed of the two axes
control
working for interpolation drive constant.
