34.4 Technical data
34.4.1 DC motor driver
The rated uninterrupted current for the motor should not exceed the
specified value of 3.5 A continuously.
This also applies to the motor's deceleration and startup when the motor is
repeatedly switched off and on.
The maximum let-through energy during motor startup is defined by integral
I
2
dt. The I
2
T value is the integral of the square of the current over a
specified period of time. It is also a measurement of the maximum energy
that the load output can deliver.
