Error
Description Solution
16#1803
Linear count exceeding the set
accumulated to the maximum and go back to the
minimum, the error code will be cleared.
16#1804
The variation in relation to a SSI encoder
position exceeding the limit on CH1
Check if there is any interruption and check the device
specification to see if the offset setting is matching with
the actual placement. When the next reading is normal,
the error code will be cleared.
16#1805
The variation in relation to a SSI encoder
position exceeding the limit on CH2
16#1806
Abnormal SSI communication on CH1
Check the execution of DHCCNT instruction. If it is
parity check, check is there is any interruption and
check if the data format is correct. Check if the device
wiring is secure, and if the encoder power supply is
16#1807
Abnormal SSI communication on CH2
16#1808
SSI absolute position cross zero point on
CH1
Check the SSI absolute encoder specification and
modify the setting accordingly. If the alarm is not
required, disable the alarm output function in
HWCONFIG. Use any of the followings to clear the
error code: clear, reset, preset the counter, restart the
module, or execute DHCCNT instruction again.

SSI absolute position cross zero point on
CH2

Troubleshooting for the Load Cell Module AS02LC
12.3.4.1 ERROR LED Indicators Are ON
You can set up HWCONFIG to have the following errors appear as warnings when they occur. Otherwise, when an error
occurs, only an error message appears.
Error
Description Solution
Hardware failure (that is, the driver board)
16#1607 The external voltage is abnormal. Check the power supply.
12.3.4.2 ERROR LED Indicators Blinking Every 0.2 Seconds
The following errors are specified as warnings to ensure that the CPU module can still run even when the warnings are
triggered by its AIO modules. The following first 3 error codes are set as warnings by default in HWCONFIG; CPU must
STOP running immediately when the first 3 errors occur.
Error
Description Solution
The external voltage is abnormal.

Check the signal received by channel 1 and the cable
connections.
16#1809
The signal received by channel 1
exceeds the weight limit.
Check the value input to channel 1 and the maximum
16#180A
The factory calibration in channel 1 is
incorrect.
Check the weight calibration in channel 1.
16#180B
The signal received by channel 2
exceeds the range of analog inputs or the
SEN voltage is abnormal.
Check the signal received by channel 2 and the cable
connections.
