* 1. SERVOPACKs with a capacity of 50 to 400 W do not have built-in regenerative resistors. If the
regenerative energy exceeds the specified value, connect an external regenerative resistor. Refer to
11.1.3 Calculating the Required Capacity of Regenerative Resistors.
* 2. Regenerative resistor power losses are allowable losses. Take the following action if this value is
exceeded.
• Remove the lead from the internal regenerative resistor in the SERVOPACK.
• Install an external regenerative resistor.
Note: External regenerative resistors are optional. Refer to 5.7 Connecting Regenerative Resistors and
4.4.3 External Regenerative Resistor for details.
