Driving by External Signal

It is possible to control each axis by external signals. The +/- direction

fixed pulse driving and continuous driving can be also performed through

the external signals. This function is used for JOG or teaching modes, and

will share the CPU load.

Input/ Output Signal

Each axis has 4 points of input signals to perform deceleration and stop in

driving. These input signals are for high-speed near-by home search,

home search and z-phase search during the home returning. Each axis is

with 8 output points for general output.

Servo Motor Feedback Signals

Each axis includes input pins for servo feedback signals such as in-posi-

tioning, close loop positioning control and servo alarm.

Interrupt Signals

Interrupt signals can be generated when: (1). The start / finish of a con-

stant speed drive during the trapezoidal driving, (2). The end of driving,

and (3). The compare result once higher / lower the border-lines of the

position counter range. An interrupt signal can be also generated during

the interpolation driving.

Real Time Monitoring

During the driving, the present status such as logical position, real

position, drive speed, acceleration / deceleration, status of accelerating /

decelerating and constant driving can be read.
