3-20 Step Instructions
PULSE OUTPUT
PLS2
@PLS2
887
P: Port specifier
M: Output mode
S: 1st word of set-
tings table
F: 1st word of
starting frequency
PLS2(887) is used to set the pulse frequency and acceleration/deceleration
rates, and to perform pulse output with acceleration/deceleration (with different
acceleration/deceleration rates). Only positioning is possible.
Output
Required
ACCELERATION
CONTROL
ACC
@ACC
888
P: Port specifier
M: Output mode
S: 1st word of set-
tings table
ACC(888) is used to set the pulse frequency and acceleration/deceleration
rates, and to perform pulse output with acceleration/deceleration (with the
same acceleration/deceleration rate). Both positioning and speed control are
possible.
Output
Required

STEP DEFINE
STEP
008
STEP(008) functionS in following 2 ways, depending on its position and
whether or not a control bit has been specified.
(1)Starts a specific step.
(2)Ends the step programming area (i.e., step execution).
Output
Required
STEP START
SNXT
009
SNXT(009) is used in the following three ways:
(1)To start step programming execution.
(2)To proceed to the next step control bit.
(3)To end step programming execution.
