Instructions Manual
2‑3. Basic Specifications
No. Item Specifications
1 Number of 4 axes
control axes
2 Pulse output Output type ・Independent direction output/Specified direction output/
function Phase‑differential signal output
・Line driver output
Output frequency ・Independent drive ：0.1 Hz to 6.5 MHz
・Interpolation drive：0.1 Hz to 5 MHz
5000 ms/kHz to 0.0025 ms/kHz (Trapezoid/S‑curve)
Acceleration/deceleration
time constant
Trapezoid/S‑curve(This feature enables to set asymmetrical
Acceleration/deceleration
shape shape)
Triangular drive ・During S‑shaped acceleration/deceleration drive, INDEX
prevention function drive may end before the maximum speed is reached.
In this event, triangular drive can be automatically
avoided.
Number of output pulses ・JOG drive : ‑65,535 to +65,535 pulse
・SCAN drive : Up to infinite pulses
・INDEX drive : ‑2,147,483,647 to + 2,147,483,647 pulses
3 Encoder Input type ・Incremental
function ・Line receiver input
Input range ・〜5MHz
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.
4 Drive JOG drive ・Pulses are constantly output until the specified pulses.
・Pulses are continuously output until a stop command is detected.
function SCAN drive
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 ・Linear interpolation is performed toward the specified
interpolation drive coordinates from the current coordinates.
・Driving type is selected from INDEX drive or SCAN drive.
・Max speed is 5MHz.
・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
interpolation drive coordinates 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 5MHz.
・Positional errors for the specified circuit curve are ±1
LSB.
・The relative addresses range from ‑8,388,607 to +8,388,607
(24 bits).
・Short axis pulses range from
‑2,147,483,648 to +2,147,483,647 (32 bits).
Linear speed constant ・Control is performed to keep the synthesized speed of the
control two axes working for interpolation drive constant.
