Pulse output instructions

Part III FP Instructions
Initial and final speed
Target speed
Acceleration time
Deceleration time
X-axis target value
Y-axis target value
The following parameters for each axis are calculated upon execution of the instruction and stored
in the operation result area of the DUT.
X-axis initial and final speed
X-axis target speed
Y-axis initial and final speed
Y-axis target speed

5000 X-axis target value (channel 0)
2000 Y-axis target value (channel 1)
Pulses are output from the X-axis (channel 0) and the Y-axis (channel 1), so that the initial speed is
500Hz, the target speed is 5kHz, and the acceleration time and deceleration time is 300ms. The
two axes are controlled so that a linear path is followed to the target position.
Pulses are output using a duty of 25%.
With the pulse output method "pulse/direction", pulses are output approx. 300s after the direction
signal has been output; the motor driver characteristics are simultaneously taken into
consideration.
General programming information
Pulse output stops when the target value is reached.
The target value for each axis must be within the range of -8388608–8388607.
When this instruction is used in combination with other pulse output instructions,
e.g. F171_PulseOutput_Trapezoidal (see page 1045), the target value in these
instructio
ns must be withi
n the same range.
When using in applications requiring precision, test runs with the actual machine
are necessary.
If both the main program and the interrupt program contain code for the same
channel, make sure both are not executed simultaneously.
When a pulse output instruction is executed and pulses are being output, the
pulse output control flag (e.g. sys_bIsPulseChannel0Active) of the corresponding
channel is TRUE. No other pulse output instruction can be executed as long as
this flag is TRUE.
When programs are being edited in RUN mode, pulse output stops but resumes
after the program changes have been downloaded.
