A
Actual ratio Actual gearbox ratio resulting from the ratio of the motor speed to the maxi-
mum speed of the application.
Additional drive element A dedicated gearbox or a downstream ratio to the gearbox.
B
Base process power Product of the max. torque and max. speed.
Braking during operation Repeated braking from full speed, preferably used for uncontrolled drives.
Brake chopper Electrical brake unit, additionally requiring an external brake resistor.
Brake module Electrical brake unit, combining the brake chopper and brake resistor in one
drive.
Braking unit Generic term for brake module and brake chopper.
C
Continuous braking power Power that can be continuously dissipated by the brake system.
Continuous power Power that can be dissipated by the inverter in continuous operation if a
standard useful life is required.
Continuous rated curve Thermal characteristic curve for continuous operation.
D
Derating Decrease of rated values under specific preconditions.
Disengagement time Time from the start of the release of the mechanical brake to the decrease to
10 % of the rated torque.
Drive analysis
Drive end
Side to which a motor is attached.
E

when the
brake is activated and the rise time t
12
of the braking torque.
F
Feedback energy The regenerative energy to be received by the brake resistor.
G
Group drive Several identical motors are supplied by one drive controller and together
power an application.
