! WARNING
ERROR CODE D1008 P-N low voltage [XX].
The voltage between P-N supplied to the power block is 60 VDC or less at servo on.
Because motor power is not supplied, when low voltage
occurs, the arm will fall until the error is detected. As a
result, other errors may be generated (abnormal speed,
deviation error, etc.).
