NOTE
When using the pulse output instructions F171_PulseOutput_Trapezoidal,
F171_PulseOutput_Home, F172_PulseOutput_Jog, F174_PulseOutput_DataTable,
F175_PulseOutput_Linear, specify an initial frequency of 30kHz or less.
Otherwise, the first pulse may be lost.
Counter and pulse output settings as well as elapsed values are stored in special data
registers. The pulse output status is stored in special internal relays. To access special data

Description
Provides trapezoidal (table-shaped) control for
automatically obtaining pulse outputs. The initial
speed, target speed, acceleration/deceleration time,
and target value need to be specified.
Permits automatic home return operation.
Causes pulses to be output as long as the execution
condition is TRUE. A target value can also be set, so
that pulse output stops when the target value is
matched.
Permits positioning control in accordance with the
specified parameters.
Causes pulses to be output using linear interpolation
control. Composite speed, acceleration/deceleration
time, and target value need to be specified.
Causes pulses to be output using circular interpolation
control. The center position needs to be specified.
Causes pulses to be output using circular interpolation
control. The pass position needs to be specified.
