10.2.5 Triangular speed
This speed profile does not have a phase of constant speed in contrast to the
trapezoidal profile. The acceleration phase is immediately followed by the de‐
celeration phase.

10.3 Duty cycle and torque
10.3.1 General
The relative duty cycle ED specifies the duty cycle percentage of the load
with respect to a total duty cycle time, including idle time. The thermal load
capacity of the motor limits the duty cycle. Loading the motor with a continu‐
ous rated torque is possible during the entire duty cycle time. To avoid ther‐
mal overload at motors with higher torques, reduce the duty cycle at M > M
N
(see fig. 10-15 ).
