 Do not use a separate device to switch ON or OFF motor during operation. Otherwise, the T-verter may experience an over-current breakdown.  When momentary power loss is longer than 2 seconds (the large of horse power, the longer of time), the inverter does not have enough storage power to[r]

Analog encoders produce sine waves thatmust be conditioned by external circuitry for counting, but digitalencoders include circuitry for translating[r]

for Distributed Generation systems. The most convenient arrangement is to use an asynchronous generator, even if it shows some drawbacks. In particular, it requires reactive power for the excitation of its magnetic circuits and, in the case of failure of the mains, it does not work in a stand alone[r]

In addition to a programmable acceleration limit, many commercial controllers allow separate acceleration and deceleration limits, or different acceleration limits in each direction. Either these limits must be conservative limits or the acceleration and deceleration in each direction must be invari[r]

This is not surprising when you consider that the unitsof the product are [1/(V*A)]*[(N*M)/(Rad/Sec)], which isthe same as mechanical power divided by electricalpower.If voltage were to be applied to an ideal motor from anideal voltage source, it would draw an infinite amount ofcurrent[r]
