2 Functions of Devices in DVP-PLC The timing diagram for the constant speed output section is shown below. Frequency Number of pulses DVSPO sets the target frequency ( S 1 ) DVSPO sets the number of pulses ( S 2 ) to K0 (no limit on the number of output pulses). DICF sets the number of pulses which need to be output in the constant speed output section ( S 1 +2). DICF and M1528 are used to reach the target frequency and the target number of pulses in the constant speed output section. The acceleration/deceleration is complete, and M1542 is set to On.
The target number of pulses in the constant speed output section is reached, M1543 is set to On, and Note: Whenever the constant speed output section is executed, the instruction resets the reaching flag and the M1542 is reset to Off. (The output used is Y0.) completion flag.1. The flags corresponding to the axes used to execute the constant speed output section are shown below.
