This instruction can be executed only while pulse outputs are stopped. ThePV cannot be changed while pulses are being output. If the PV needs to bechanged, be sure to stop the pulse output first.2. This instruction can be used only for changing the frequency and stoppingthe pulse output. It cannot be used for switching between independentmode and continuous mode. Moreover, ACC(––) cannot be received duringacceleration or deceleration.110SectionCPM2A/CPM2C Pulse Output Functions2-5The following table shows the words and bits related to pulse outputs with trapezoidal acceleration and deceleration (fixed duty ratio).WordBitsNameContentsCannot be used aswork bits even whennot used as pulseoutputs.22800 to 15 Pulse output PV 0, rightmost 4 digits22900 to 15 Pulse output PV 0, leftmost 4 digits252AR 1104Pulse output 0 PV resetClears PV 0 when ON.11Pulse output status for pulse output 0ON: Accelerating ordeceleratingOFF: Constant speed12Pulse output 0 PV overflow/underflow131415ON: OccurredOFF: NormalNumber of pulses set for pulse output 0 ON: SetOFF: Not setPulse output completed for pulseON: Completedoutput 0OFF: Not completedPulse output in progress for pulseON: In progress (byoutput 0SPED(64), ACC(––),or PWM(––))OFF: StoppedSet Number of PulsesSpecify the number of pulses to be output in independent mode.(@)PULS(65)000DNFixed at 000: Pulse output 0Type of Pulse Output (000: Relative pulses; 001: Absolute pulses) (See note.)Beginning word of setting for number of pulsesNRightmost 4 digitsN+1Leftmost 4 digitsNumber of pulses (Rightmost, leftmost digits)Register the number of pulses to be set.96,777,215 to 16,777,215Negative numbers are expressed by turningON the leftmost bit.Type of Pulse Output000:Relative pulses (SV for number of pulses = Number of pulses moved)001:Absolute pulses (SV for number of pulses = The next PV on the absolute coordinate system,i.e., the pulse output PV + number of pulses moved)**Absolute pulses can only be specified by PULS(65) when the PV coordinate systemin the PC Setup is set for an absolute coordinate system.111SectionCPM2A/CPM2C Pulse Output Functions2-5Set Frequency and Start Pulse OutputsChange FrequencyThese functions set the output mode, the target frequency, the starting frequency, and the acceleration/deceleration rate, and they begin pulse outputs.
