High-Speed Input and Pulse Output Features
DL105 PLC User Manual, 3rd Edition
Mode 30: Pulse Output
The HSIO circuit in Mode 30 generates
output pulse trains suitable for open-loop
control of a single-axis motion positioning
system. It generates pulse (stepper
increment) and direction signals which
you can connect to motor drive systems
and perform various types of motion
control. Using Mode 30 Pulse Output, you
can select from three profile types:
Trapezoidal Profile
Time
Accel
Decel
Velocity
S
Trapezoidal
-- Accel Slope to Target Velocity to Decel Slope
S
Registration
-- Velocity to Position Control on Interrupt (also used for
home search moves)
S
Velocity Control
-- Speed and Direction only
The HSIO circuit becomes a high-speed pulse generator (up to 7 kHz) in Mode 30.
By programming acceleration and deceleration values, position and velocity target
values, the HSIO function automatically calculates the entire motion profile. The
figure below shows the DL105 generating pulse and direction signals to the drive
amplifier of a stepper positioning system. The pulses accomplish the profile
independently and without interruption to ladder program execution in the CPU.

DL105 Micro PLC
In the figure above, the DL105 generates
pulse and direction signals. Each pulse
represents the smallest increment of
motion to the positioning system (such as
one step or micro-step to a stepper
system). Alternatively, the HSIO Pulse
Output Mode may be configured to deliver
counter clock-wise (CCW) and clock-wise
(CW) pulse signals as shown to the right.

NOTE:
The pulse output is designed for open loop stepper motor systems. This, plus
its minimum velocity of 40 pps make it unsuitable for servo motor control.
