11. OPTIONS AND AUXILIARY EQUIPMENT
(c) MR-J3-11KB(4) to MR-J3-22KB(4) (when using the supplied regenerative resistor)
When using the regenerative resistors supplied to the servo amplifier, the specified number of resistors
(4 or 5 resistors) must be connected in series. If they are connected in parallel or in less than the
specified number, the servo amplifier may become faulty and/or the regenerative resistors burn. Install
the resistors at intervals of about 70mm. Cooling the resistors with two cooling fans (92 92, minimum
air flow : 1.0m
3
) improves the regeneration capability. In this case, set " FA" in parameter No. PA02.

Note. The number of resistors connected in series depends on the resistor type. The thermal sensor is not mounted on the
attached regenerative resistor. An abnormal heating of resistor may be generated at a regenerative circuit failure. Install a
thermal sensor near the resistor and establish a protective circuit to shut off the main circuit power supply when abnormal
heating occurs. The detection level of the thermal sensor varies according to the settings of the resistor. Set the thermal
sensor in the most appropriate position on your design basis or use the thermal sensor built-in regenerative option (MR-
RB5E, 9P, 9F, 6B-4, 60-4 and 6K-4) provided by Mitsubishi Electric Corporation.
