4. Functions

SMC-4DF-PCI, SMC-8DF-PCI

LTC (counter latch input)

Signal to latch with the counter value, allowing the counter value to be cleared immediately after

latching or an interrupt request to be generated upon latching. The input logic can be changed by

software.

PCS (positioning control start input)

Signal for overriding (replacing) the target position, allowing positioning to be performed by the set

amount of shifting from the input-ON timing. The input logic can be changed by software.

CLR (counter clear input)

It is a signal to reset a specified counter. Selecting edge input or level input and resetting multiple

counters are available. The input logic can be changed by software.

General-purpose output signals

This product has general-purpose output signals (OUT1 - OUT3) in addition to pulse output signal.

In addition, output signals can be switched to alarm clear output, driver differential clear output, or

comparator output by software.

OUT1 - OUT3 (General-purpose output signals)

OUT1 - OUT3 (general-purpose output signals) can be used to write data to I/O ports. Since these are

independent of motor control, they do not affect pulse output even during motor operation.

There are 3 pins for each axis, which are used for the output of level output signals for servo-on and

hold-off to the motor driver unit, one-shot pulse signals for various clear signals, and comparator output

signals. The output logic can also be changed by software.

ALMCLR (alarm clear output signal), ERC (driver differential clear output)

ALMCLR and ERC are signals to output clear one-shot pulses to the alarm clear and deviation counter

clear inputs of the motor driver unit. The width of one-shot pulses (output logic changeable) can be

selected from among 12 μsec, 102 μsec, 408 μsec, 1.6 msec, 13 msec, 52 msec, 104 msec.

CP1, CP2 (comparator output)

CP1 and CP2 compare the count value with the set comparator value. Signals will be output when the set

criteria are satisfied. The output logic can be changed by software.

P.COM (Plus common)

P.COM is the plus common signal for limit input signals (+LIM, -LIM, SD, ORG) and general-purpose

input/output signals (IN1 - IN7, OUT1 - OUT3).

GND (Ground)

GND is the ground line for the general-purpose output signals (OUT1 - OUT3).
