Notes: 1. Be sure to cool the unit forcibly with a cooling fan (92 mm × 92 mm, minimum air flow: 1.0 m 3 /min). The cooling fan must be prepared by user. 2. The value in brackets is applicable when cooling fans (two units of 92 mm × 92 mm, minimum air flow: 1.0 m 3 /min) are installed, and then [Pr. PA02] is changed. 3. The servo amplifier built-in regenerative resistor supports the maximum torque deceleration when the servo motor is used within the rated speed and the recommended load to motor inertia ratio. Contact your local sales office if the operating motor speed or the load to motor inertia ratio exceeds the rated speed or the recommended ratio. 4. The power values in this table are resistor-generated powers, not rated powers. 5. This is the resultant resistance when three units of MR-RB13V-4 are connected in parallel. 6. The regenerative resistor enclosed with the servo amplifiers 11 kW to 22 kW does not have a protective cover, and touching the resistor (including the wiring screws) may cause a burn or an electric shock. Provide safety measures such as a protective cover or use MR-RB_ regenerative option. * Cautions when connecting the regenerative option 1. The regenerative option causes a temperature rise of 100 °C or higher relative to the ambient temperature. Fully examine heat dissipation, installation position, wires used before installing the unit. Use flame-retardant wires or apply flame retardant on wires, and keep the wires clear of the unit. 2. Use twisted wires for connecting the regenerative option to the servo amplifier, and keep the wire length to a maximum of 5 m. 3. Use twisted wires for connecting a thermal sensor, and make sure that the sensor does not fail to work properly due to inducted noise.
