Ishida OMNi-4000 Error Codes and Troubleshooting
15.4a SERVO CONTROLLER ERROR CODES (0430 - 0011~0097)
The Lift Servo has built-in protection. When an error occurs the error code is displayed on the 7-segment display.
CAUTION

Over speed error
Motor speed exceeds the velocity limit.
1. Check if excess speed command is given.
2. Check if acceleration overshoot is generated due to gain
adjustment failure.
0430
28
Protection against
external scale
In full closed control mode when parameter No. 76
(scale error ineffective) is 0, scale error input [X4 pin
Check for the error factor of the external scale.
0430
29
Error counter
overflow
Position error count is 134217728 or more.
1. Check if the motor runs according to the position command.
2. Use the torque monitoring function to check if the output torque
is saturated.

35
Protection against
external scale
connection error
Error such as a broken wire occurred on connection
of external scale.
Error of external scale.
1. Check the power supply of the external scale.
2. Check the wire connection of the external scale.
0430
36
EEPROM
parameter error
Reset all the parameters and write into EEPROM.
0430
37
EEPROM check
code error
The Servo Driver might be defective.
0430
39
Emergency stop
input error
The Servo Driver gets tripped when emergency stop
input becomes active.
1. Check if anything is wrong with the switch (sensor), electric lines,
and power source that are connected to the emergency stop input.
2. Make sure the emergency stop input (X5, pin2) is closed.
3. Check if control signal power (12 to 24VDC) is started later
compared to the Servo Driver when power is turned on.

40
Absolute system
down error
All the power supplies for the encoder are down.
After connecting the battery perform a complete memory clear.
0430
41
Absolute encoder
counter over flow
error
Encoder multi-turn counter exceeds the specified
value.
1. Set parameter No. 0B absolute encoder setup to appropriate value.
2. Moving amount from the machine home should be within 32767 turns.
0430
42
Absolute encoder
over speed error
Turning amount exceeds the specified value when
battery power alone is supplied.
1. Check CN SIG connection state.
2. Check the power voltage (5V ± 5%) on the encoder side.
0430
44
Absolute encoder
single-turn counter
error
Encoder detects single-turn counter error
0430
45
Absolute encoder
multi-turn counter
error
Encoder detects multi-turn counter error
0430
47
Absolute encoder
status error
Encoder is running higher than the specified value at
power ON.
Prevent the motor from running when powered ON.
EEPROM parameter error occurs if the data is
broken when data is read from EEPROM at power
ON.
The motor might be defective.
