Alarm List for A06B-6058-Hxxx
A06B-6058 Series Servo Units are equipped with LEDs to indicate alarm condition.
A20B-1003-0090 (A06B-6058-Hxxx)
A16B-1200-0800 (A06B-6058-H2xx)
A16B-1100-0330 (A06B-6058-H3xx)
5V: This is not an alarm. Indicates that power is applied to the amplifier
DRDY: Indication that the drive unit is ready state and the motor is energized.
HV: High Voltage Alarm The DC link voltage has exceeded
the limit.
If the alarm is constant at power on/ when the motor is energized,
the problem is most likely the drive unit.
HC: High Current Alarm DC link current is excessive.
If
the alarm is constant, disconnect the motor leads U, V, W, and GND.
Power on
again and if the problem persists, the drive unit is the issue.
If no more HC
alarm with motor leads disconnected, the problem may be the motor or the motor
power cables.
LV: Low Voltage Alarm DC link voltage is low.
Check the
incoming voltage on the T1 terminal block (G, A, 1, 2) for a proper voltage.
If
the correct voltages present, the issue may be the drive unit problem.
DC: Discharge Alarm Discharge circuit capacity has been
exceeded.
Check the external discharge unit, jumper S1, S2 settings.
OH: Overheat Alarm
Check the thermostats on discharge
unit, in the servo amplifier or the servo transformer.
When using the discharge unit,
(1) Remove the short bar
from Terminal T2 (4 & 5).
(2) Connect the cable from the discharge unit to
T2 (4 & 6).
(3) Connect the thermostat cable of the discharge unit to T4.
Set the S1 jumper to "L" and S2 to "H"
