2C-776Av1
Instructions Manual
Serial interface control block
This department is control block for AL-
serial communication.
Ⅱ
The AL-
serial communications interface department is insulated with +24 V power supply and the internal logics.
Ⅱ
Serial interface control block
This department is control block for serial communication of Extend unit.
This block performs an Extend I/O unit and serial communication and can extend the I/O of 32 points /32 points
input output at the maximum .
(
)
The serial communication interface part is insulated from power 24 V.
Drive control block
The drive control block outputs serial pulses to the motor driver from pulse generator MCC.
(
)
MCC is made by MELEC Inc.
This department detects origin sensor and a limit sensor signal and motor is controlled.
・
Enables four axes independent drive, or two axes X-axis and Y-axis, Z-axis and A-axis
linear interpolation drive,
・
(
)
and circular interpolation drive.
Enables stop four axes at immediate stop by FSSTOP signal from the outside.
・
To distinguish four axes, it is named X-axis, Y-axis, Z-axis, and A-axis.
Counter block
The counter block has three types of counters: ADDRESS COUNTER, PULSE COUNTER, and DFL COUNTER.
(
)
Can use as hard timer.
ADDRESS COUNTER, PULSE COUNTER has 32-bit counter, and DFL COUNTER has 16-bit counter.
The 2C-776Av1 has a variety of application such as counting feedback pulses from the servo driver, detecting step-
out of the stepping motor with an encoder.
The applications also include interrupt output and external signal output using the comparator function of each
counter.
General-purpose I/O block
This block is controlling the following input/output.
These input/output ports can control easily by I/O-function.
General-purpose I/O area
・
The reading of the general-purpose Input IN0 signal and IN1 signal, the operation of the general-purpose
…
output OUT0 signal and OUT1 signal are possible.
Moreover, enables operation as Latch signal and Clear signal of X-axis SS0 signal by the IN0 signal input.
And, enables operation as Latch signal and Clear signal of Y-axis SS1 signal by the IN1 signal input.
Extend I/O area
・
When the area secure an extension input/output area for 32 points /32 points input/output and access it
…
from an application in this input/output area, the area can control input/output by an Extend I/O unit
and cyclic communication.
Control I/O area
・
The interface of SERVO ON, ALARM CLEAR, and SERVO READY signal is possible as the servo driver's
…
control I/O.
This Control I/O signal is reflected in each servo interface signal of the driver connector.
(
)
SIGNAL I/O block Applied function
This is a block where the external equipment such as cameras etc. and the interface can be done by open
collector output or line driver differential
output signal.
(
)
An arbitrary status signal of X-axis or Y-axis default value = CNTINT
can be output external equipment.
(
)
A real-time system with which OS of the personal computer doesn't relate is possible according to this interface.
User Interface block
This department is interface block for the motor drivers, sensor signals, and general-purpose input and output
equipment.
