It gets the pulse frequency andoutput pulse count values, and reads status of up and down direction “U/D”, so as to determine the directionto be upward or downward. As the reset finished, this instruction will check the input status of pause output“PAU”. No action will be taken if the pause output is 1 (output pause). If the PAU is 0, it will start to outputthe ON/OFF pulse with 50% duty at the frequency Fr to the UY(U/D=1) or DY(U/D=0) point. It will incrementthe value of HO register each time when a pulse is output, and will stop the output when HO register’s pulsecount is equal to or greater than the cumulative pulse count of PC register and set the output complete flag“DN” to 1. During the time when output pulse is transmitting the output transmitting flag “OUT” will be set to 1,otherwise it will be 0.• Once it starts to transmit pulse, the output control “EN” should kept to 1. If it is changed to 0, it will stop thepulse sending (output point become OFF) and the flag “OUT” changes back to 0, but the other status or datawill keep unchanged. However, when its “EN” changes again from 0 to 1, it will lead to a reset action andtreat as a new start; the entire procedure will be restarted again.• If you want to pause the pulse output and not to restart the entire procedure, the ‘pause output’ “PAU” inputcan be used to pause it. When “PAU” =1, this instruction will pause the pulse transmitting (output point isOFF, flag “OUT” change back to 0 and the other status or data keeps unchanged). As it waits until the“PAU” changes back from 1 to 0, this instruction will return to the status before it is paused and continues thepulse transmitting output.• During the pulse transmission, this instruction will keep monitoring the value of pulse frequency Fr and outputpulse count PC. Therefore, as long as the pulse output is not finished, it may allow the changing of the pulsefrequency and pulse count. However, the up/down direction “U/D” status will be got only once when it takesthe reset action (“EN” changes from 0→1), and will keep the status until the pulse output completed oranother reset occur. That is to say, except that at the very moment of reset, the change of “U/D” does notinfluence the operation of this instruction.• The main purpose of this instruction is to drive the stepping motor with the UY (upward) and DY (downward)two directional pulses control, so as to help you control the forward or reverse rotating of stepping motor.Nevertheless, if you need only single direction revolving, you can assign just one of the UY or DY (which willsave one output point), and leaving the other output blank. In such case, the instruction will ignore theup/down input status of “U/D”, and the output pulse will send to the output point you assigned.7-63
Advanced Function <strong>Instruction</strong>FUN 81 PLSOPULSE OUTPUTFUN 81 PLSO• When MD=1, the pulse output will reflect on the control output DIR (pulse direction. DIR=1, up; DIR=0, down)and CK (pulse output).• This instruction can only be used once, and UY (CK) and DY (DR) must be transistor output point on the PLCmain unit.• The effective range of output pulse count PC for 16 bit operand is 0~32767. For the 32 bit operand(instruction), it is 0~2147483647. If the PC value = 0, it is treated as infinite pulse count, and this instructionwill transmit pulses without end with HO value and “DN” flag set at 0 all the time. The effective range of pulsefrequency (Fr) is 8~2000. If the value PC or Fr exceeds the range, this instruction will not be carried out andthe error flag “ERR” will set to 1.X0X1X281D.PLSOEN MD : 0Fr : R 0PAU PC : R 1UY : Y 0U/D DY : Y 1HO : R 5OUTDNERRM0M1• In this example, the program controls the stepping motorto drive forward for 80 pulses (steps) at the speed of100Hz first, and then makes it turn reverse for 40 pulsesthe speed of 50Hz.
