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.
