Pulse I/O Board Section 2-2
Trapezoidal Pulse Output
With Different
Acceleration/Deceleration
The following flowchart shows the procedure for using PULS(65) and
ACC(––) to perform trapezoidal pulse outputs with different acceleration/
deceleration rates.
Determine port mode.
Determine pulse output port.
Mount Board and wire output.

Simple Positioning Mode:
All functions of ACC(−−) can be used.
High-speed Counter Mode:
Modes 1 to 3 of ACC(−−) can be used; Mode 0 (Acceleration + Indepen-
dent) is disabled.
Port 1 or port 2.
Output:
CW/CCW with/without 1.6 kΩ resistance.
Power supply for output: 5/24 V DC
Port Mode Setting (DM 6611):
Set to High-speed Counter Mode (0000 Hex) or Simple Positioning Mode
(0001 Hex). See note.
Operation settings for ports 1 and 2 (DM 6643/DM 6644):
Set to fixed duty factor.
Note: ACC(−−) Mode 0 (Acceleration + Independent) cannot be used in
High-speed Counter Mode.
SET PULSES, PULS(65):
Set number of output pulses for each port.
ACCELERATION CONTROL, ACC(−−):
Port-specific trapezoidal acceleration/deceleration pulse output control with
different acceleration/deceleration rates.
MODE CONTROL, INI(61):
Stop pulse output to a specified port.
HIGH-SPEED COUNTER PV READ, PRV(62):
Read pulse output status of a specified port.
