CAUTION
The power supply voltage for the robot controller must always be regulated
within ±10%. If the voltage drops, the robot controller may issue an abnormal
voltage alarm causing the robot to trigger emergency stop. In contrast,
operation at a voltage higher than specifi ed may damage the robot
controller or trigger emergency stop due to detecting an excessive motor
power supply voltage.
Prepare a suitable power supply while referring to the tables below.
