Trapezoidal Pulse Output
With Same Acceleration/
Deceleration
The following flowchart shows the procedure for using PLS2(––) to perform
trapezoidal pulse outputs with the same acceleration/deceleration rate.
Simple Positioning Mode
(PLS2(
−−
) cannot be used in High-speed Counter Mode .)
Port 1 or port 2.
Output:
CW/CCW with/without 1.6 k
Ω
resistance.
Power supply for output: 5 V DC/24 V DC
Port mode setting (DM 6611):
Simple Positioning Mode (DM 6611 to 0001 Hex). See Note.
Operation settings for ports 1 and 2 (DM 6643/DM 6644):
Set to fixed duty factor (0000 Hex).
(PLS2(
−−
) cannot be used in High-speed Counter Mode .)
PULSE OUTPUT, PLS2(
−−
):
Port-specific trapezoidal acceleration/deceleration pulse output control with
same acceleration/deceleration rate.
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.
Determine port mode.
Determine pulse output port.
Mount Board and wire outputs.
