connected loosely. Connect it correctly. 1) The control circuit power
supply connector was
disconnected. Loose
connection
Check the control circuit
power supply connector.
It has no problem. Check 2).
It is lower than
17VDC. Increase the voltage of the
control circuit power
supply. 2) The voltage of the control
circuit power supply is low.
Check if the voltage of
the control circuit power
supply is lower than
17VDC.
The voltage is over
17VDC. Check 3).

the main circuit
power
3) The alarm has occurred
during acceleration.
The bus voltage is
35VDC or higher when
48VDC is set for the
main circuit power
supply, or 15VDC or
higher when 24VDC is
set for the main circuit
power supply. The voltage is
35VDC or lower
when 48VDC is set
for the main circuit
power supply, or
15VDC or lower
when 24VDC is set
for the main circuit
power supply. Increase the acceleration
time constant. Or increase
the power supply capacity.
