6 OPTIONS
6.1 INTRODUCTION
The AD1000 has several options. Some of the most requested are
described in this chapter; contact Nidec-Asi for special needs.
6.2 DYNAMIC BRAKING
6.2.1 BRAKING UNIT
The AD1000 series “F” (excluding sizes AD1A350-520), if required,
can be equipped with an internal braking unit installed at the factory.
The product code identifies the braking unit with the 10th character;
the letter “B” in the 10th position indicates that the brake is mounted
inside, while the letter “N” indicates that the AD1000 has no braking
unit installed (See Chapter 2 for further details).
The braking unit is required when the braking torque requested
exceeds 15% than the rated torque of the motor provided in the
“Electrical data” table in chapter 2.5. The maximum braking torque
allowed using the braking unit cannot exceed 150% of the rated
torque of the motor.
The braking unit is supplied without resistor that can be calculated
using the formulas in section 6.2.3.
The braking device is able to handle a continuous calculated braking
power equal to 50% of the motor rated power (see paragraph 2.5
“Electrical data”).
NOTE:
For critical yield cycles (e.g. lifting applications) consult
the manufacturer.
