Check 3) and 4).
10.2 Voltage drop in
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.
