Note)
Servo error data is stored in the SERVO PCB's EEPROM mem-
ory. As the power is unstable immediately after being turned
ON, data written to the EEPROM at this time will be incorrect.
To ensure accuracy, the DA-98HR prohibits data from being
written to the EEPROM for 10 seconds after POWER ON. If an
error occurs just 10 seconds, the error data is not stored in mem-
ory. As a result, the servo error history stored in the memory
may differ from actual phenomena.
