1. TROUBLESHOOTING FOR SERVO AMPLIFIER (DRIVE UNIT)
1 - 101
Alarm No.: 9A Name: Optional unit input data error warning
Alarm content The BCD input data setting is incorrect when MR-D01 extension IO unit is connected.
Detail
No.
Detail name Cause Check method Check result Action Target
9A.1 Optional unit
input data sign
error
(1) The MR-D01 extension
IO unit is not
connected.
Check if MR-D01 is
connected correctly. It is not connected. Connect it correctly. [A]
It is connected. Check (2).
(2) Both of + and - signs
are on or off.
Check the sign of the
optional unit input
data. Both are on or both
are off. Turn on one of the
signs only.
Only one of the
signs is on. Check (3).
(3) The - sign is set at
incremental value
command.
Check the sign of the
optional unit input
data. The - sign is set. Set it to +.
The + sign is set. Check (4).
(4) The MR-D01 extension
IO unit is
malfunctioning.
Replace the MR-D01,
and then check the
repeatability. It is not repeatable. Replace the MR-
D01.
9A.2 Optional unit
BCD input data
error
(1) Other than "0" to "9" is
set in a digit.
Check the BCD input
data. A value out of range
is set. Set a value from "0"
to "9".
Alarm No.: 9B Name: Error excessive warning
Alarm content Droop pulses have exceeded the warning occurrence level.
Detail
No.
Detail name Cause Check method Check result Action Target
9B.1 Excess droop
pulse 1 warning
(1) The servo motor power
cable was
disconnected.
Check the servo
motor power cable. It is disconnected. Repair or replace
the servo motor
power cable. [A]
[B]
[WB]
[GF]
It is not
disconnected. Check (2).
(2) The connection of the
servo motor is incorrect.
Check the wiring of
U/V/W. It is incorrect. Connect it correctly.
It is correct. Check (3).
(3) The connection of the
encoder cable is
incorrect.
Check if the encoder
cable is connected
correctly. It is incorrect. Connect it correctly.
It is correct. Check (4).
(4) The torque limit has
been enabled.
Check if the limiting
torque is in progress. The limiting torque
is in progress. Increase the torque
limit value.
The limiting torque
is not in progress. Check (5).
(5) A moving part collided
against the machine.
Check if it collided. It collided. Check operation
pattern.
It did not collide. Check (6).
(6) The torque is
insufficient.
Check the peak load
ratio. The torque is
saturated. Reduce the load or
review the operation
pattern. Or use a
larger capacity
motor.
The torque is not
saturated. Check (7).
(7) Power supply voltage
dropped.
Check the bus voltage
value. The bus voltage is
low. Check the power
supply voltage and
power supply
capacity.
The bus voltage is
high. Check (8).
(8) Acceleration/
deceleration time
constant is too short. Set a longer
deceleration time
constant, and then
check the
repeatability. It is not repeatable. Increase the
acceleration/
deceleration time
constant.
It is repeatable. Check (9).
