User Manual of EM760 High-Performance Inverter The terminals VX1 to VX8 essentially have the same function, but there are no corresponding physical terminals actually. They all have the positive and negative logic functions. The terminals VX1 to VX4 have the delay function, and their statuses can be confirmed in the same way. They can be set separately. The terminal VX1 is taken as an example below. ● When F17.09=xxxxxxx0, the VX1 status is the same as the VY1 output status. As stated literally, the status of the virtual input terminal is the same as that of the virtual output terminal, so this should be used in conjunction with the virtual output terminal.
If F17.19=16 (reach the length) and F17.28=xxxx xxx1 (the VY1 status depends on the output function status) under the default conditions, and “16: reach the length” is valid, the VY1 output and VX1 synchronization will be valid. The corresponding operations (length count clearing and VY1 output status resetting) can be performed according to the VX1 setting (assuming “39: length clearing”). Then the fixed length count function can be enabled again to meet the requirements for repeated processing. If there are certain intervals between repeated processing procedures, you can also complete the aforesaid operations by setting the VX1 delay.
