9 Troubleshooting
■
E136.1: Encoder communication error
Direct cause:
1. The encoder cable is disconnected.
2. The encoder communication is disturbed.
Root Cause
Confirming Method
Solution
The FPGA and motor encoder
communication is faulty
during initialization upon
power-on.
Observe the value of H0B-28 to see
whether it is not 0.
Check whether the encoder cables are
connected properly.
Check whether the motor model is set
properly.
Check whether H01-00 (MCU firmware
version) and H01-01 (FPGA firmware
version) are set properly.

E150.0: STO signal input protection activated
Direct cause:
The STO input protection applies (safety state).
Root Cause
Confirming Method
Solution
1. The STO is activated.
Check whether the STO function is
activated.
There is no need to take any actions. Clear
the fault through fault reset after the STO
terminal is restored.
2. The STO power supply is
abnormal.
Check whether the 24 V power
supply for the STO is stable.
Tighten the cables that are loosened or
disconnected.
3. The STO is deactivated.
The fault persists after preceding
actions are taken.
Replace the servo drive.

E150.1: STO signal input error
Direct cause:
The single-channel input of STO is invalid.
Root Cause
Confirming Method
Solution
1. The STO power supply is
abnormal.
Check whether the 24 V power
supply for the STO is stable.
Tighten the cables that are loosened or
disconnected.
2. The STO input resistor is
abnormal.
The 24 V power supply is
disconnected due to resistor drift
after the STO function is enabled,
but the single-channel STO input is
normal.
Replace the servo drive.
3. The STO is deactivated.
The fault persists after preceding
actions are taken.
Replace the servo drive.
■
E150.2: Abnormal voltage detected
Direct cause:
The MCU monitors the 5 V power supply provided to the PWM Buffer to detect whether overvoltage and
undervoltage occurs. If the voltage is abnormal, E150.2 will be displayed.
Root Cause
Confirming Method
Solution
The 5 V power supply provided to
the Buffer is abnormal.
Check the 5 V power supply.
Replace the servo drive.
