Description of Safety
This product must be handled correctly.
Handling the product incorrectly may cause unexpected accidents resulting in personal injuries or
damage to your properties.
Many of those accidents can be avoided if you have advance information on dangerous situations.
This manual provides precautions where dangerous situations are predicted. The manual provides the
following alert marking and messages for this purpose:
This indicates a hazardous situation that could result in death or serious
WARNING 
personal injury if you do not perform the procedure correctly.
This indicates a potentially hazardous situation that could result in personal
CAUTIONinjury or physical damage if you do not perform the procedure correctly.
Before Use
■Set up the product before operating it.
Refer to Section 3, "Setting."
■This product is equipped with a LIMIT (overtravel) signal and an FSSTOP signal to prevent mechanical
damage.
The initial values of these signals are set to ACTIVE OFF (B contact). Accordingly, even in a
system configuration in which the FSSTOP and LIMIT signals are not used, pulses are not output
unless NORMAL ON (GND connection) is enabled.
■The C‑VX875 allows axes to be controlled independently and therefore referred to each axis
as follows:
1st axis 2nd axis 3rd axis 4th axis
X axis Y axis Z axis A axis
・AL‑Ⅱ I/O communication of C‑VX875 explains C‑VX875 as a master board.
・This manual basically explains only the X axis.

１．OVERVIEW
1‑1. Features
● The C‑VX875 is controller equipped with four independently functioning axes.
This controller supports servo and stepping motors that can directly be inserted into slots of a PCI
bus system conforming to PCI bus specifications R2.2.
・From RJ‑45 connector of a front panel, a maximum of four slave I/O units of AL‑Ⅱ series are
connectable by AL‑Ⅱ I/O communication.
Moreover, an Extended I/O unit can also be extended to a slave I/O unit.
Thereby, 4 axes motor control and the I/O system of a maximum of 256 points/256 points can be
built by one PCI slot.
・The board shape is the universal short card size (107 x 170) of the PCI bus standard.
● The C‑VX875 is equipped with our chip controller MCC07 to enable motor control using simple commands.
・C‑VX875 enables four independently linear interpolation driving, 2‑axis linear interpolation
(fixed interpolation‑axes) or 2‑axis circular interpolation (fixed interpolation‑axes) driving.
Moreover,the C‑VX875 is enable to optional axes liner interpolation drive or Optional 2‑axis
(Applied function)circular interpolation drive.
・The 32‑bit width address counter and the maximum output frequency of 6.5 MHz of the MCC07 enables
high‑precision, high‑speed positioning.
・Also equipped with a multi‑functional 32‑bit pulse counter, and 16‑bit pulse differential counter,
the C‑VX875 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.
・After the command being executed is finished, the commands stored in the reservation register are
(Applied function)executed sequentially. Then this function can be allowed continuous drive.

■Signal table
This product may be damaged.
CAUTION Do not connect +24V to any pin other than EXTV.
After wiring, be sure to confirm the wiring before power‑on.
● A signal indicated by is photocoupler‑insulated.
● A signal is enable to set time constants marked with ☆.(Applied function)
● Logic switching is enabled for an input signal marked with ★.(Applied function)
Logic switching is enabled for general‑purpose input signal INx,
when this signal is used for DALM function
(Note 1)
An external power supply is required for a signal that is photocoupler‑insulated.
The specified input voltage range is +24V ±2V.
Current consumption at +24V is up to 200mA.
The initial values of the CWLM and CCWLM signals of each axis and the FSSTOP signal are
ACTIVE OFF input (B contact).
An external power supply must be connected even if these signals are not used.
The default contact B is recommended for the CWLM and CCWLM signals.
However, A‑contact signal input can also be used by switching logic.
(Note 2)
SENSORx input signals are used for multipurpose sensor function, synchronization control
function. These input signals is used by any functions setting.(Applied function)
The initial value after resetting is as follows:
SENSOR0 signal is SS0 of Z‑axis, SENSOR1 signal is SS0 of A‑axis.
When SENSORx input signal is used for multipurpose sensor function, this signal can not use
in MANUAL mode.
When MANUAL mode, the functions of multipurpose sensor assigned to the SENSORx input signal
are invalid.
When BUS mode, this function are valid.

・All input signal is not able to set time constants, to switch logic.
(Note 1) When the MAN signal goes low, this bord is MANUAL mode.
When the MAN signal goes high, this bord return to BUS mode.
The MAN RDY signal is enable to go high by MAN MASK command.
When the MAN signal is low level, this bord is not MANUAL mode by setting MAN signal low level.
(Note 2) SIGNAL INx input signal can be use general‑purpose sensor function and synchronous start
function. If these signal is used, set the functions that need to be changed from their values.
The initial value after the relevant signal is reset is "No function" .
If this bord is MANUAL mode, You can not use SIGNAL INnx input signal.
When this bord is MANUAL mode, this signal(SEL A‑D) enable to select an axis that perfoms
MANUAL SCAN drive.
The functions assigned to the SIGNAL INnx input signal are invalid. And when this bord
returns to BUS mode, the functions assigned to this signal are valid.
(Note 3) SIGNAL OUTnx output signal can be output status signals of any axes by setting status output
function. The initial values after the relevant signal is reset are as follows:
SIGNAL OUTn0 is CNTINT signal of Xn axis. SIGNAL OUTn1 is CNTINT signal of Yn axis.
(Note 4) When this bord is MANUAL mode, SS0,SS1 input signal(SEL A‑D) enables general‑purpose sensor
that MANUAL SCAN drive specified axis.
When general‑purpose sensor function is set as "UP/DOWN/CONST command", this input signal
enable acceleration/deceleration command signal of MANUAL SCAN drive.
