Note: Regenerative resistor power losses are allowable losses. Take the following action if this value is
exceeded:
• Disconnect the internal regenerative resistor in the servo amplifier by removing the wire
between terminals B2 and B3.
•
Install an external regenerative resistor between terminals B1 and B2.
See 5.6 Selecting a Regenerative Resistor for more details on the resistors.
