Pulse Outputs
Section 5-2
ACCELERATION
CONTROL: ACC(888)
Use ACC(888) to set the target frequency and acceleration and deceleration
rate and output pulses with acceleration and deceleration. (Acceleration rate
is the same as the deceleration rate.)
Either independent mode positioning or constant mode speed control is possi-
ble when used in combination with PULS(886). ACC(888) can also be exe-
cuted during pulse output to change the target frequency or acceleration/
deceleration rate, enabling smooth (sloped) speed changes.
PULSE OUTPUT:
PLS2(887)
Use PLS2(887) to set the startup frequency, acceleration rate, and decelera-
tion rate, and output a specified number of pulses. 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.
