Description
When a speed control operation started with the
ACC(888) instruction (continuous) is in progress,
another ACC(888) instruction (continuous) can be exe-
cuted to change the acceleration rate or deceleration
rate.
When a positioning operation started with the ACC(888)
instruction (independent) or PLS2(887) instruction is in
progress, another ACC(888) (independent) or
PLS2(887) instruction can be executed to change the
acceleration rate or deceleration rate.
When a speed control operation started with the
SPED(885) instruction (continuous) or ACC(888)
instruction (continuous) is in progress, the PLS2(887)
instruction can be executed to switch to positioning, out-
put a fixed number of pulses, and stop.
When operating in absolute coordinates (with the origin
determined or INI(880) instruction executed to change
the PV), the CW or CCW direction is selected automati-
cally based on the relationship between the pulse output
PV and the pulse Output Amount specified when the
pulse output instruction is executed.
When a positioning operation started with the ACC(888)
instruction (independent) or PLS2(887) instruction is in
progress, triangular control (trapezoidal control without
the constant-speed plateau) will be performed if the
number of output pulses required for acceleration/decel-
eration exceeds the specified target pulse Output
Amount.
(The number of pulses required for acceleration/deceler-
ation equals the time required to reach the target fre-
quency x the target frequency.)
Two built-in outputs can be used as PWM(891) outputs 0
and 1 by executing the PWM(891) instruction.
