User Manual of EM760 High-Performance Inverter The Y1 and Y2 multi-function output ports are of open collector output type, with YCM as the common output port. If the selected function is disabled, the electronic switch will be OFF, and the multi-function output ports will be in the invalid status. If the selected function is enabled, the electronic switch will be ON, and the multi-function output ports will be in the valid status. The open collector can be powered on internally or by an external power supply (12-30V). The output of the relay, one of the standard supplies, is from the internal relay ofthe inverter.
Each relay has one set ofnormally open contacts and one set of normally closed contacts. When the selected function is disabled, the EB-EC (RB-RC) is normally closed and EA-EC (RA-RC) is normally open. When the selected function is enabled, the internal relay coil will be powered on, the EB-EC (RB-RC) will be disconnected, and the EA-EC (RA-RC) Fig. 6-21 Relay contact will be engaged. As shown in the right figure. Fig. 6-22 Schematic Diagram of Level and Single Pulse Output of Digital Output Terminal The digital output terminal has two output types: level and single pulse, as shown in the figure above.
For the level output, the output status of the function terminal is consistent with the function status; and for the single pulse output, the active level of a certain pulse width will not be outputted until the function is enabled. This function code is subject tobit operation. For specific settings, refer to the description ofthe function code F02.15 under 6.5.1. 133 72 FDT2 lower limit (pulse, invalid in JOG) 73 Output overcurrent When this function of the output terminal is enabled, the current exceeds the F15.66 overcurrent detection level, and the duration reaches the value ofF15.67, the output will be valid.
