High-speed Counter/Pulse Output Instructions Section 3-21
Applicable Program Areas
Operands P: Port Specifier
The port specifier indicates the port. The parameters set in D and N will apply
to the next SPED(885) or ACC(888) instruction in which the same port output
location is specified.
T: Pulse Type
T specifies the type of pulses that are output as follows:
N and N+1: Number of Pulses
N and N+1 specify the number of pulses for relative pulse output or the abso-
lute target position for absolute pulse in 8-digit hexadecimal.
The actual number of movement pulses that will be output are as follows:
For relative pulse output, the number of movement pulses = the set number of
pulses. For absolute pulse output, the number of movement pulses = the set
number of pulses
− the PV.
