AppendixA-9Appendix 3 Fault CodesCode Display Fault Description Retry0 — — — No fault No fault recorded. ×1 (EmS) EmergencystopIndicates that sequence signal EMS has been input in C00-4 = 2 (faultoutput at emergency stop) mode.×2 (PM-n) PowerModulePower module faultn: sub-code 1: during stop 2: during operation atthe set speed3: during acceleration 4: during deceleration5: during braking 6: during ACR7: during pre-extension 9: during automatic tuning3 (OC-n) OvercurrentThe output has risen to or beyond 300%.n: sub-code 1: during stop 2: during operation atthe set speed3: during acceleration 4: during deceleration5: during braking 6: during ACR7: during pre-extension 9: during automatic tuning4 (OV-n) OvervoltageThe DC voltage has risen to or beyond the preset level. (Vdc ≥ 800 or400V)n: sub-code 1: during stop 2: during operation atthe set speed3: during acceleration 4: during deceleration5: during braking 6: during ACR7: during pre-extension 9: during automatic tuning5 (UV-n) UndervoltageWhile the drive is running, the DC voltage has lowered to or beyond thepreset level (65% of the rating).n: sub-code 1: during stop 2: during operation atthe set speed3: during acceleration 4: during deceleration5: during braking 6: during ACR7: during pre-extension 9: during automatic tuningAt C08-0 = 2, 3 (automatic start), only the symbol displays, so the FLTLED and terminal block FA, FB and FC contacts will not operate. EC0 to3 will operate.×6 Not defined7 Overheat The heatsink temperature has risen to or beyond 95°C. 8 Overspeed Indicates that the motor speed exceeded the overspeed setting value(C24-0).×9 Not definedA (ATT-n) AutomatictuningabnormalcompletionThis indicates that the automatic tuning did not complete normally.n: Automatic tuning step No. (when interrupted)(1) ACR simple setting(2) Single-phase AC measurement(3) ACR adjustment(9) Excitation inductance measurement(A) Secondary resistance measurement(B) Max. torque boost adjustment(C) Excitation inductance fluctuation table adjustment×B (OL-n) Overload Indicate that the output current exceeded the thermal operation timehaving inverse time characteristics. The standard characteristics are150% for one minute in respect to the motor rated current. At 155% ormore in respect to the inverter rated current, this will be 170% for 2.5seconds.n: Sub-code 1: Drive output overloadC (GRD. n) Ground The Drive has sensed a grounded conditions on the output.n: sub-code 1: during stop 2: during operation atthe set speed3: during acceleration 4: during deceleration5: during braking 6: during ACR7: during pre-extension 9: during automatic tuning
