14.OPTIONS AND AUXILIARY EQUIPMENT

Before connecting any option or auxiliary equipment, make sure that the charge WARNING lamp is off more than 10 minutes after power-off, then confirm the voltage with a

tester or the like. Otherwise, you may get an electric shock.

CAUTION	Use the specified auxiliary equipment and options. Unspecified ones may lead to a
	fault or fire.

14.1 Options

14.1.1 Regenerative brake options

CAUTION	The specified combinations of regenerative brake options and servo amplifiers
	may only be used. Otherwise, a fire may occur.

(1)Combination and regenerative power

The power values in the table are resistor-generated powers and not rated powers.

Note: Always install a cooling fan.

(2)Selection of the regenerative brake option

(a)Simple selection method

In horizontal motion applications, select the regenerative brake option as described below: When the servo motor is run without load in the regenerative mode from the running speed to a stop, the permissible duty is as indicated in Section 5.1 of the separately available Servo Motor Instruction Manual.

For the servo motor with a load, the permissible duty changes according to the inertia moment of the load and can be calculated by the following formula:

Permissible Permissible duty for servo motor with no load (value indication Section 5.1 in Servo Motor Instruction Manual) duty

ratedspeed

running speed

2

[times/min]

where m load inertia moment/servo motor inertia moment

From the permissible duty, find whether the regenerative brake option is required or not. Permissible duty number of positioning times [times/min]

Select the regenerative brake option out of the combinations in (1) in this section.
