Overview
The DL405 high-speed counter provides
high-speed up or down counting capability. It provides the user with count data
and output signals such as Clockwise,
Counter-clockwise, Decelerate, and
Equal. The module functions asynchronously with the DL405 CPU, allowing fast
response and control.
The D4-HSC module supports the
following key features:
• Quadrature or up/down encoder input
• Maximum input pulse rate of 100 kHz (50%
duty cycle)
• Seven user control inputs
• Four external outputs for controlling motor
modes
• Counting range from –8,388,608 to +8,388,607
with overflow
• Counter input multiplication of
X1, X2, or X4
• User selectable count direction
• A or B mode selection
A mode to reset counter at preset
B mode to continue counting after preset
• Find Home mode to search for home position
• Sampling count to determine pulse rate

Process
Quadrature counting
Relays/
Timers
With a rotary encoder, the leading and lagging signals are
determined by which direction the shaft is turning. This is
how quadrature counting is able to sense direction.

External Module Input Descriptions
Internal Interface Signals from
DL405 CPU to D4-HSC
IN A
Depending on mode chosen, this is either a standard UP/DOWN counter input, or one of the
quadrature counter inputs.
IN B
Depending on mode chosen, this is either a standard UP/DOWN counter input, or one of the
quadrature counter inputs.
Reset Overflow
IN Z
This input can be used to help you find home position for positioning control. It can also be
used as an external means of resetting the counter.
Enabled HSC RUN
LD (Load)
If you want to use an offset number with your counting, a rising edge signal at this terminal
will copy the offset value into the current count.
RST (Reset)
A high (ON) signal at this terminal resets the counter to zero and it remains there until there
is a transition to a low signal (OFF)
LATCH
You may want to store the current count. The rising edge of a signal at this terminal will
store the current count in shared RAM. Counting continues with no interruption.
C.INH
You may want to temporarily ignore the count inputs coming in on INA and INB. A high (ON)
signal at this terminal will inhibit the counting to accomplish this need. Current count is
suspended until a transition to a low (OFF) signal is seen.
Reset Current Count
RUN
Not to be confused with Run mode of the DL405, a high (ON) signal here will activate HSC
RUN. A low (OFF) signal will deactivate it.
Change Count Direction
LS1 and LS2
Either or both of these terminals can be connected to limit switches to help find home
position, or they can merely be used as discrete inputs.

External Module Output Descriptions
CW
Clockwise – Turns on when the optional HSC RUN mode is invoked and the current count is
less than the preset value. It will reset when the current count equals the preset value. This
output can also be controlled independently from the count values with an internal output bit
allocated to the HSC.
CCW
Counter Clockwise – Turns on when the optional HSC RUN mode is invoked and the current
count is greater than the preset value. It will reset when the current count equals the preset
value. It can also be controlled independently from the count values with an internal output
bit allocated to the HSC.
OUT1
OUT2
Deceleration – If the optional HSC RUN mode is active, this output turns on when the
current count equals the deceleration value. It is reset when HSC RUN mode is exited and
re-entered, or when an internal output bit allocated to the HSC is enabled.
Brake – If the optional HSC RUN mode is active, this output turns on when the current count
equals the preset value. It is reset when HSC RUN mode is exited and re-entered, or when an
internal output bit allocated to the HSC is enabled.
