The following flowchart shows the procedure for using PULS(65) and
SPED(64) to perform single-phase fixed duty factor pulse outputs without
acceleration or deceleration.
Pulse output port 1 or 2.
Output:
CW/CCW with/without 1.6 k Ω resistance.
Power supply for output: 5/24 V DC
Port Mode Setting (DM 6611): Sets to High-speed Counter
Mode (0000 Hex) or Simple Positioning Mode (0001 Hex).
Operation settings for ports 1 and 2 (DM 6643/DM 6644):
Set to fixed duty factor.
SET PULSES, PULS(65):
Set number of output pulses for each port.
SPEED OUTPUT, SPED(64):
Port-specific pulse output control without acceleration/
deceleration.
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.
