DVP-ES3 Series Programming Manual Symbol S ： Pulse output frequency D 1 ： Pulse output device D 2 ： Pulse direction output device _6 Explanation 1. This instruction adjusts the pulse output frequency and direction ( S ) for the devices specified in D and D 2 . S specifies the pulse output frequency: for open collector output models, the range is between -200 kHz to +200 kHz. The minus sign and plus sign indicate the positive direction and negative pulse direction.
You can change the pulse output frequency during the pulse output; but if the new frequency is different from the previous frequency in direction, the instruction stops the output, and one cycle later it outputs the target frequency again in a new direction. 2. Refer to the table below for pulse output devices for D 1 and D 2 . When the output mode for D 1 and D 2 is not the default Pulse+direction output (0 is the default value), set SR to 1, which changes the mode to A/B phase output.
