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 50 to 400W 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 Alarm Display Table when the Application Module is Used.
* 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 7.5 kW.
The following regenerative resistor units are provided for this purpose.
For the SGDH-75DE: JUSP-RA18 (allowable loss: 180W)
For the SGDH-75AE: JUSP-RA05 (allowable loss: 350W)
Note: Refer to
