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 11.3.
The brake unit is rated for a short duration. Do not use it for high duty.
When the dynamic brake is used, the power supply voltage is restricted as
indicated below.
