4.4 SERVOPACK's Power Supply Capacities and Power Losses

The following table shows SERVOPACK's power supply capacities and power losses at the rated output.

* 1. SERVOPACKs with a capacity of 30 to 400W do not have built-in regenerative resistors. If the regenerative
energy exceeds the specified value, connect an external regenerative resistor. Refer to 12.1.3 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 (optional).
* 3. An external regenerative resistor must be connected to SERVOPACKs with a capacity of 6.0 kW or higher. The
following regenerative resistor units are provided for this purpose.
For the SGDM-60ADA: JUSP-RA04 (allowable loss: 180W)
For the SGDM-75ADA to 1EADA: JUSP-RA05 (allowable loss: 350W)
Note: Refer to 6.5 Connecting Regenerative Resistors, 5.8.6 External Regenerative Resistor and 5.8.7 Regenerative
Resistor Unit for details.
