(c) MR-J2S-11KA to MR-J2S-22KA (when using the supplied regenerative brake resistor)
When using the regenerative brake 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 brake
resistors burn. Install the resistors at intervals of about 70mm. Cooling the resistors with fans
(1.0m

/min, 92 (about two fans) improves the regeneration capability. In this case, set "0E " in
parameter No. 0.

Note. The number of resistors connected in series depends on the resistor type. Install a thermal sensor or like to configure a
circuit that will shut off the main circuit power at abnormal overheat. The supplied regenerative brake resistor does not
have a built-in thermal sensor. If the regenerative brake circuit fails, abnormal overheat of the resistor is expected to
occur. On the customer side, please also install a thermal sensor for the resistor and provide a protective circuit that will
shut off the main circuit power supply at abnormal overheat. The detection level of the thermal sensor changes depending
on the resistor installation method. Please install the thermal sensor in the optimum position according to the customer's
design standards, or use our regenerative brake option having built-in thermal sensor (MR-RB65, 66, 67).
