Alarm No.10 Name: Undervoltage Stop method: All axes stop
Alarm description
Voltage of the control circuit power has dropped.
Voltage of the main circuit power has dropped.
Display Name Cause Checkpoint Finding Action
10.1 (1) Check the connector of
the control circuit power. Disconnected or
poorly connected. Connect properly. Voltage drop in
the control circuit
power Connector for the control
circuit power is
disconnected or poorly
connected.
No problem found. Check (2).
(2) Voltage of control circuit
power is low.
160VAC or less. Increase the voltage in
the control circuit
power. Check if the control circuit
power voltage is 160VAC
or less.
Over 160VAC. Check (3).
(3) Instantaneous control
circuit power failure of
60ms or longer.
Check the power supply
for a problem. Problem found. Check the power
supply.
10.2 (1) Disconnected. Connect properly. Voltage drop in
the main circuit
power Connector for the main
circuit power is
disconnected. Check the connector of
the main circuit power.
No problem found. Check (2).
(2) Voltage of main circuit
power is low.
160VAC or less. Increase the voltage in
the main circuit power. Check if the main circuit
power voltage is 160VAC
or less.
Over 160VAC. Check (3) and (4).
(3) Voltage drops during
acceleration.
Check if the bus voltage
is 200VDC or more
during acceleration. Below 200VDC. Set acceleration time
longer or increase the
power supply
capacity.
(4) Servo amplifier is faulty. Check the bus voltage
using MR Configurator. The main circuit power
supply voltage is
160VAC, but the bus
voltage measured
using MR Configurator
is less than 200VDC. Replace the servo
amplifier.
