8.3.4 Motor output uprating and derating
The continuous output current available from the MotiFlex
e
100 will often differ from the nominal
value suggested by the model name. For example, depending on the chosen overload type and
switching frequency, the continuous output rating of a 16 A model can be derated to as little as
8.5 A, or uprated to as much as 22 A. When operating a motor at very low speeds or holding it
stationary, other ratings apply since these conditions represent abnormal operating modes for the
MotiFlex
e
100. In addition to these rating adjustments, if the MotiFlex
e
100 is operating in an
ambient temperature greater than 45 ºC (113 ºF), a further derating must be applied. The choice
of overload rating and switching frequency can be selected using the Drive Setup Wizard in Mint
WorkBench, or by using the
DRIVERATINGZONE
keyword. See the Mint help file for details.
8.3.5 Motor output rating adjustment - 1.5 A model
The continuous current rating of the MotiFlex
e
100 is affected by the chosen overload type and
switching frequency, as shown in Table 21. These settings can be selected in the Mint
WorkBench Drive Setup Wizard - see the Mint help file for details.
