(2) Selection of the regenerative option
(a) Simple selection method
In horizontal motion applications, select the regenerative 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 option is required or not.
Permissible duty number of positioning times [times/min]
Select the regenerative option out of the combinations in (1) of this section.
Before connecting any option or peripheral equipment, turn off the power and wait
for 15 minutes or more until the charge lamp turns off. Then, confirm that the
voltage between P and N is safe with a voltage tester and others. Otherwise, an
electric shock may occur. In addition, always confirm from the front of the servo
amplifier whether the charge lamp is off or not.
Use the specified auxiliary equipment and options. Unspecified ones may lead to a
fault or fire.
The specified combinations of regenerative options and servo amplifiers may only
be used. Otherwise, a fire may occur.
