■Switching the input terminal logic between sink and source
Input terminals of the
When switching between sink logic and source logic, do it before connecting cables to inverter’s control circuit terminals. When the confirmation message G or G is displayed after switching between sink logic and source logic, using the H parameter, reset the inverter, using the operation panel, by turning the power off, or by inputting a reset signal from an external control device.
■Switching the VI/S3 terminal between logic input and analog input
The VI/S3 terminal of the
If switching between contact input and analog input is done after cable connection, the inverter and/or the external device connected might be damaged. Before turning on the inverter, make sure all cables are connected correctly to the control terminals.
When using the VI/S3 terminal as an contact input terminal (sink logic), be sure to insert a resistor* between the P15 and VI/S3 terminals. (Recommended resistance:
■Switching the FM/OUT terminal between meter output (PWM output) and open collector output
The FM/OUT terminal of the
When switching between meter output (PWM output) and open collector output, do it before connecting an external device to the inverter. After switching from meter output (PWM output) to open collector output, and vice versa, check using the HOUN parameter to be sure that the desired function is assigned to the FM/OUT terminal, and then turn the power off. After the completion of cable connection, turn the power back on. If switching between meter output and open collector output is done after cable connection, the inverter might be damaged.
