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 8.3.
• 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. Set 1 in parameter No. 3.
