(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 duty for servo motor with no load (value indication Section 5.1 in Servo Motor Instruction Manual)
Permissible
duty
where m
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.
Before connecting any option or auxiliary equipment, make sure that the charge
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.
Use the specified auxiliary equipment and options. Unspecified ones may lead to a
fault or fire.
The specified combinations of regenerative brake options and servo amplifiers
may only be used. Otherwise, a fire may occur.
