INSTALLATION AND WIRING 2.6 Control circuit Type Terminal symbol Common Terminal name Terminal function description Rated specification Refer to page Relay A1, B1, C1*1 — Relay output 1 (fault output) 1 changeover contact output that indicates that an inverter's protective function has been activated and the outputs are stopped. Fault: discontinuity across B and C (continuity across A and C), Normal:
continuity across B and C (discontinuity across A and C) Contact capacity: 230 VAC 0.3 A (power factor = 0.4), 30 VDC 0.3 A 490 A2, B2, C2*1 — Relay output 2 1 changeover contact output 490 Open collector RUN*1 SE Inverter running The output is in LOW state when the inverter output frequency is equal to or higher than the starting frequency (initial value: 0.5 Hz). The output is in HIGH state during stop or DC injection brake operation. Permissible load: 24 VDC (27 VDC at maximum) 0.1 A (The voltage drop is 2.8 V at maximum while the signal is ON.) The open collector transistor is ON (conductive) in LOW state. The transistor is OFF (not conductive) in HIGH state.
490 SU*1 SE Up to frequency The output is in LOW state when the output frequency is within the set frequency range ±10% (initial value). The output is in HIGH state during acceleration/deceleration and at a stop. Fault code (4 bits) output. (Refer to page 510.) 501 OL*1 SE Overload warning The output is in LOW state when stall prevention is activated by the stall prevention function. The output is in HIGH state when stall prevention is canceled. 448 IPF*1 SE Instantaneous power failure The output is in LOW state when an instantaneous power failure occurs or when the undervoltage protection is activated.
647, 654 FU*1 SE Frequency detection The output is in LOW state when the inverter output frequency is equal to or higher than the preset detection frequency, and is in HIGH state when it is less than the preset detection frequency. 501 Pulse FM*2 SD For meter Among several monitor items such as output frequency, select one to output it via these terminals. The signal is not output during an inverter reset. The size of output signal is proportional to the magnitude of the corresponding monitor item. Use Pr.55, Pr.56, and Pr.866 to set full scales for the monitoring output frequency, output current, and torque. (Refer to page 474.) Output item:
