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 Motors Standard counting using one input Steppers/ Servos Motor Controls Proximity Sensors Standard counting using two inputs Photo Sensors Limit Switches Encoders Pushbuttons/ Lights 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. Comm. TB’s & Wiring Power Output control Enclosures Appendix Part Index CW is the clockwise signal output. It is just one of four possible outputs. w w w. a u to m at i o n d i re c t . c o m / d l 405 PLC Products 6–57 High-speed Counter Module 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.

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.
