POINT
Configure up a sequence which switches off the contact of the brake unit
after (or as soon as) it has turned off the servo on signal at a power failure
or failure.
For the braking time taken when the dynamic brake is operated, refer to
section 12.3.
The brake unit is rated for a short duration. Do not use it for high duty.
(1) Selection of dynamic brake
The dynamic brake is designed to bring the servo motor to a sudden stop when a power failure occurs
or the protective circuit is activated, and is built in the 7kW or less servo amplifier. Since it is not built
in the 11kW or more servo amplifier, purchase it separately if required. Set " 1
