Regulator failure
Overhaul voltage regulator
E471 (0x) Driver board undervolt-
age
1. Insufficient voltage, the external
input voltage is too low
2. Harmonic interference
1. Replace the power supply or add a
regulator
2. It is necessary to install a special filter
at the input end of the servo drive to
solve the problem
E472 (0x) Driver board hardware
overcurrent
1. The power supply voltage is too
large
2. The hardware is damaged, result-
ing in too small resistance
1. Buck treatment
2. Replace the hardware
E473 (0x) Driver board software
overcurrent
