Pulse Outputs Section 5-3
Pulse Output with Trapezoidal Acceleration/Deceleration (Using PLS2(887))
5-3-8 Instructions used for Pulse Outputs
The pulse output functions can be used by executing the pulse control instruc-
tions in the ladder program. For some instructions, the PLC Setup must be set
in advance. The following instructions can be combined for positioning and
speed control.
Supported Pulse
Instructions
Use the following 8 instructions to control the pulse outputs.
Determine the pulse output
method, output frequency, and port.
Wire the outputs.
PLC Setup settings
• Enable/disable the origin search function. Set the
various origin search parameters if the origin
search function is enabled.
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.
• Pulse output method
• CW/CCW inputs: Pulse outputs 0 to 3
• Pulse + direction inputs: Pulse outputs 0 to 3
Pulse outputs 0 and 1 use the same pulse output method.
• Output frequency
• X/XA models:
Unit version 1.1 and later:
Pulse outputs 0 to 3: 1 Hz to 100 kHz (1 Hz units)
Unit version 1.0 and earlier:
Pulse outputs 0 and 1: 1 Hz to 100 kHz (1 Hz units)
Pulse outputs 2 and 3: 1 Hz to 30 kHz (1 Hz units)
• Y models:
Pulse outputs 0 and 1: 1 Hz to 1 MHz (1 Hz units)
Pulse outputs 2 and 3: 1 Hz to 100 kHz (1 Hz units)
