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.
