3.4 SERVOPACK Power Losses
The following table shows SERVOPACK power losses at the rated output.
* 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.
* 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
5.5 Connecting Regenerative Resistors
4.4.6 External Regenerative Resistor
for details.
