Pulse Outputs Section 7-6
• Set the clock speed for pulse outputs 1 and 2.
4. Create the necessary ladder programming.
• Use PULS(886) to set number of output pulses for the specified port.
• Use SPED(885) to start pulse output control without acceleration/deceler-
ation from the specified port.
• Use INI(880) to stop pulse output from the specified port.
• Use PRV(881) to read the pulse output PV of the specified port.
Pulse Outputs with Acceleration/Deceleration
This procedure shows how to use PULS(886) and ACC(888) to generate a
pulse output with acceleration or deceleration. The number of output pulses
cannot be changed during positioning.
1,2,3... 1. Determine pulse output port.
• Select pulse output 1 or 2.
2. Wire the output.
• Output: CW and CCW
• Output power supply: 5 V DC
3. Make the necessary System Setup settings (Pulse Output Tab Page
− Op-
eration Mode).
• Set the pulse output operation mode (in the Pulse Output Tab Page
−
Operation Mode) to relative pulse output, absolute linear pulse output, or
absolute circular pulse output.
• Set the clock speed for pulse outputs 1 and 2.
4. Create the necessary ladder programming.
• Use PULS(886) to set number of output pulses for the specified port.
• Use ACC(888) to start pulse output control with acceleration or decelera-
tion from the specified port (acceleration and deceleration are specified
separately).
• Use INI(880) to stop pulse output from the specified port.
