• Universal DO -- U-DO (Function code data = 27) Assigning this output signal to an inverter's output terminal and connecting the terminal to a digital input terminal of peripheral equipment via the RS-485 communications link or the fieldbus, allows the inverter to send commands to the peripheral equipment. The universal DO can also be used as an output signal independent of the inverter operation. For the procedure for access to Universal DO via the RS-485 communications link or fieldbus, refer to the respective instruction manual. • Heat sink overheat early warning -- OH (Function code data = 28) This output signal is used to issue a heat sink overheat early warning that allows for corrective action before an overheat trip 0h1 actually happens. This signal comes ON when the temperature of the heat sink exceeds the "overheat trip temperature minus 5°C (41°F)," and it goes OFF when it drops down to the "overheat trip temperature minus 8°C (46°F)." This signal comes ON also when the internal air circulation DC fan (75 HP or above for 230 V series or 125 HP or above for 460 V series) has locked. • Synchronization completed -- SY (Function code data = 29) This output signal comes ON when the control target comes inside the synchronization completion detection angle in synchronous running. For details about synchronous operation, refer to the PG Interface Card instruction manual. • Lifetime alarm -- LIFE (Function code data = 30) This output signal comes ON when it is judged that the service life of any one of capacitors (DC link bus capacitors and electrolytic capacitors on the printed circuit boards) and cooling fan has expired. This signal should be used as a guide for replacement of the capacitors and cooling fan. If this signal comes ON, use the specified maintenance procedure to check the service life of these parts and determine whether the parts should be replaced or not. (Refer to Chapter 7 of the user manual, Section 7.3 "List of Periodic Replacement Parts.") This signal comes ON also when the internal air circulation DC fan (75 HP or above for 230 V series or 125 HP or above for 460 V series) has locked. • Under PID control -- PID-CTL (Function code data = 43) This output signal comes ON when PID control is enabled ("Cancel PID control" (Hz/PID) = OFF) and a run command is ON. (Refer to the description of J01.) When PID control is enabled, the inverter may stop due to the slow flowrate stopping function or other reasons, with the PID-CTL signal being ON. As long as the PID-CTL signal is ON, PID control is effective, so the inverter may abruptly resume its operation, depending on the feedback value in PID control. When PID control is enabled, even if the inverter stops its output during operation because of sensor signals or other reasons, operation will resume automatically. Design machinery so that safety is ensured in consideration of these events. Otherwise, accidents could occur. 4-91
• Running forward -- FRUN (Function code data = 52) Running reverse -- RRUN (Function code data = 53) Output signal Assigned data Running forward Running reverse Inverter stopped FRUN 52 ON OFF OFF RRUN 53 OFF ON OFF • In remote operation -- RMT (Function code data = 54) This output signal comes ON when the inverter switches from local to remote mode. For details of switching between remote and local modes, refer to user <strong>Manual</strong> Chapter 4, Section 4.2.2 "Remote and local modes." • Terminal [C1] wire break -- C1OFF (Function code data = 59) This output signal comes ON when the inverter detects that the input current to terminal [C1] drops below 2 mA interpreting it as the terminal [C1] wire broken. • Speed valid -- DNZS (Function code data = 70) This output signal comes ON when the reference or detected speed exceeds the stop frequency specified by function code F25. It goes OFF when the speed is below the stop frequency for 100 ms or longer. Under vector control with speed sensor, F38 switches the decision criterion between the reference and detected speed. Under vector control without speed sensor, the reference speed is used as a decision criterion. ( Refer to the descriptions of F25 and F38.) • Alarm output (for any alarm) -- ALM (Function code data = 99) This output signal comes ON if any of the protective functions is activated and the inverter enters Alarm mode. • Enable circuit failure detected -- DECF (Function code data = 101) This output signal comes ON when the inverter detects a failure of the Enable circuit(*1). Configure a feedback circuit of the Enable input function as needed to feed back the transistor output of the DECF-assigned inverter to the reset input of the upper safety relay unit for turning the Enable command off and shutdown of the inverter output. 4-92
