Operands
PLS2(887) outputs a specified number of pulses to the specified port. Pulse
output starts at a specified startup frequency, accelerates to the target fre-
quency at a specified acceleration rate, decelerates at the specified decelera-
tion rate, and stops at approximately the same frequency as the startup
frequency. Only independent mode positioning is supported.
PLS2(887) can also be executed during pulse output to change the number of
output pulses, target frequency, acceleration rate, or deceleration rate.
PLS2(887) can thus be used for sloped speed changes with different acceler-
ation and deceleration rates, target position changes, target and speed
changes, or direction changes.
