User Manual of EM760 High-Performance Inverter The terminals VY1 to VY8 essentially have the same function, but there are no corresponding physical terminals actually. They all have the positive and negative logic functions. The terminals VY1 to VY4 have the delay function, and their statuses can be confirmed in the same way. They can be set separately. The terminal VY1 is taken as an example below. ● F17.28=xxxxxxx0: the VY1 status is the same as the actual input status of X1. The status of the virtual output terminal VY1 is synchronized with that of the actual input terminal X1. This can be applied in programming of multiple functions such as status confirmation or enabling of one switch.
● F17.28=xxxxxxx1: the VY1 status depends on the selected function status of the function code F17.19. The status of the virtual output terminal depends on the set function status, and its main output is for software programming. The PID can be controlled via “reaching the upper limit of PID feedback” as follows: outputting the signal “19: reach the upper limit of PID feedback” through the virtual output terminal VY1 (F17.19=19), collecting it through the virtual input terminal VX1 and then setting the VX1 function to “41: process PID pause” (F17.00=41). Note: The D7 bit of the VY8 option must be set to 1. That is, the VY8 function is always dependent on the output function status.
