ADAM-5240 User Manual 4
Constant Vector Speed Control
This function performs a constant vector speed. During the interpolation
driving, MCX314AS can set a 1.414 times pulse cycle for 2-axis simulta-
neous pulse output, and a 1.732-time pulse cycle for 3-axis simultaneous
pulse output that keep the constant speed during driving.
Position Control
Each axis has a 32-bit logic position counter and a 32-bits real position
counter. The logic position counter counts the output pulse numbers, and
the real position counter counts the feedback pulse numbers from the
external encoder or linear scale.
Compare Register and Software Limit
Each axis has two 32-bit compare registers for logical position counter
and real position counter. The comparison result can be read from the sta-
tus registers. The comparison result can be notified by an interrupt signal.
These registers can be also functioned as software limits.
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.
