= The motor’s cycle time.
t

= The motor’s decel time.
DC = %
How to Select a Brake
(continued)
Find the intersection of
P% and the motor’s decel time DC in the chart
below. If the point of intersection is below the curve, the duty cycle is
within the brake’s limits. If the point is above the curve, the duty cycle
is beyond the brake’s limits but may be modified by increasing the
motor’s cycle time
