User Manual of EM760 High-Performance Inverter Fig. 6-20 Schematic Diagram of Terminal Delay Sampling In the event of changes in the status ofthe function terminal,a response will be made with delay according to the function code settings. Currently only the terminals X1 to X4 support this function. Specifically, it is embodied in: This function will take effect when the function terminal changes from the invalid to valid status and is maintained with the valid delay, and not take effect when the function terminal changes from the valid to invalid status and is maintained with the invalid delay. If the function code is set to 0.00s, the corresponding delay will be invalid.
6.5.2 Digital output terminal (DO) The standard configuration ofthe EM760 series inverter includes 2 multi-function digital output terminals (Y1 and Y2) and 2 relay output terminals (R1 and R2). With the extension card inserted, support is available for another 2 relay output terminals (R3 and R4). Y1, Y2, R1 and R2 are 4 standard ways of multi-function digital output terminals. Their functions are defined by setting function codes F03.00 - F03.03. R3 and R4 are 2 extended multi- function output terminals. Their functions are defined by setting function codes F03.32 - F03.33. For example, if you define F03.02=7, the function of the R1 terminal is “inverter protection”.
When the inverter is in the protection status, the output ofthe function terminal R1 will be valid; and when the inverter is in the normal status, the output of the function terminal R1 will be invalid. Specific options are described in the table below. 129 Function code Function codename Parameter description Unit Default setting Attribute F03.00 Options ofY1 output function See Table 6-14 Function List of Multi-function Digital Output Terminals. 1 ○ F03.01 Options ofY2 output function 3 ○ F03.02 Options of R1 output function 7 ○ F03.03 Options of R2 output function 8 ○ F03.32 Options of R3 output function 0 ○ F03.33 Options of R4 output function 0 ○
