Fault
No fault No fault recorded.
Emergency Indicates that sequence signal EMS has been input in C00-4 = 2 (fault
stop output at emergency stop) mode.
Power Power module fault
Module n: sub-code
Over The output has risen to or beyond 300%.
current n: sub-code
The DC voltage has risen to or beyond the preset level. (Vdc ≥ 800 or
Over
voltage
400V)
n: sub-code
Under While the drive is running, the DC voltage has lowered to or beyond the
voltage preset level (65% of the rating).
n: sub-code
At C08-0 = 2, 3 (automatic start), only the symbol displays, so the FLT
LED and terminal block FA, FB and FC contacts will not operate. EC0 to
3 will operate.
Overheat The heatsink temperature has risen to or beyond 95°C.
Overspeed Indicates that the motor speed exceeded the overspeed setting value
(C24-0).
Automatic This indicates that the automatic tuning did not complete normally.
tuning n: Automatic tuning step No. (when interrupted)
abnormal (1) ACR simple setting
completion (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
Overload Indicate that the output current exceeded the thermal operation time
having inverse time characteristics. The standard characteristics are
150% for one minute in respect to the motor rated current. At 155% or
more in respect to the inverter rated current, this will be 170% for 2.5
seconds.
n: Sub-code 1: Drive output overload
The Drive has sensed a grounded conditions on the output.
