Built-in Outputs Section 6-2
Pulse Output with Trapezoidal Acceleration/Deceleration (Using PLS2(887))
Using CW/CCW Limit Inputs for Pulse Output Functions Other than Origin Searches
(CJ1M CPU Unit Ver. 2.0 Only)
Pulse outputs will stop when either of the CW/CCW limit input signals
(A54008, A54009, A54108, and A54109) turns ON. With the previous version
of the CJ1M CPU Units, the CW/CCW limit input signals could be used only
with origin searches. With the CJ1M CPU Unit Ver. 2.0, these signals can be
used with other pulse output functions. It is also possible to set whether to
undefine the origin when a CW/CCW limit input signal turns ON for an origin
search or other pulse output function.
Procedure
1,2,3... 1. Specify in the following PLC Setup settings whether to use the CW/CCW
limit input signals (A54008, A54009, A54108, and A54109) only for origin
searches or for all pulse output functions.
Pulse Output 0 Limit Input Signal Operation
(CJ1M CPU Unit Ver. 2.0 Only)
Determine the pulse output
method and port.
•
CW/CCW method
Pulse output 0 uses OUT0 (CIO 296100) and
OUT1 (CIO 296101).
Pulse output 1 uses OUT2 (CIO 296102) and
OUT3 (CIO 296103).
•
Pulse + direction method
Pulse output 0 uses OUT0 (CIO 296100) and
OUT2 (CIO 296102).
Pulse output 1 uses OUT1 (CIO 296101) and
OUT3 (CIO 296103).
The same pulse output method must be set for
both pulse output 0 and pulse output 1.
Wire the outputs.
Power supply for outputs: 24 V DC
PC Setup settings
•
Enable/disable the origin search function. Set the
various origin search parameters if the origin
search function is enabled.
The Origin Search Function Enable/Disable
setting for pulse outputs 0 and 1 is in the
rightmost digit (bits 00 to 03) of Programming
Console addresses 256 and 274, respectively.
Ladder program
•
PLS2(887): Specify port number and set the
output method (CW/CCW method or Pulse +
direction method) and pulse output control with
trapezoidal acceleration/deceleration (different
rates can be set for acceleration and
deceleration).
•
INI(880): Specify port number and stop pulse
output when necessary.
•
PRV(881): Specify port number and read pulse
output PV when necessary.
