A10 Undervoltage Power
supply
voltage dropped.
1. Power supply voltage is low.
<Check method>
Check that the power supply voltage
is the following value or more.
200V class: 160VAC
100V class: 83VAC
400V class: 280VAC
Check the power supply.

2. Shortage of power supply capacity
caused the power supply voltage to
drop at start, etc.
<Check method>
Check that the bus voltage is the
following value or more.
200V class: 200VDC
100V class: 158VDC
400V class: 380VDC
3. The bus voltage dropped to the
following value or less.
200V class: 200VDC
100V class: 158VDC
400V class: 380VDC
4. There was an instantaneous control
circuit power failure of 60ms or
longer
1
5. Faulty parts in the servo amplifier.
<Check method>
1. The alarm occurs even if the power
is switched on after disconnection of
all cables except the control circuit
power supply cables.
2. Check that the bus voltage is the
following value or more.
200V class: 200VDC
100V class: 158VDC
400V class: 380VDC
Change the servo amplifier.
6. The power supply voltage is
distorted.
When power impedance is high,
waveform of power supply voltage
may be distorted due to the power
regeneration current and recognized
as undervoltage.
1. Set parameter No.PC27
to "0001".
2. Review the power supply.

Faulty parts in the servo amplifier.
<Check method>
Alarm occurs even if the power is
switched on after disconnection of all
cables except the control circuit
power supply cable.
Change the servo amplifier.
