SPED(885) starts pulse output on the port specified in P using the method
specified in M at the frequency specified in F. Pulse output will be started each
time SPED(885) is executed. It is thus normally sufficient to use the differenti-
ated version (@SPED(885)) of the instruction or an execution condition that is
turned ON only for one scan.
Pulse frequency
Target frequency
SPED(885) executed.
In independent mode, pulse output will stop automatically when the number of
pulses set with PULS(886) in advance have been output. In continuous mode,
pulse output will continue until stopped from the program.
An error will occur if the mode is changed between independent and continu-
ous mode while pulses are being output.
■
Continuous Mode Speed Control
When continuous mode operation is started, pulse output will be continued
until it is stopped from the program.
