Emc Filter - Parker AC890 Product Manual

Operating the Drive
In many applications, the total power consumed by the system is less than the installed power of the drives.
This is because some drives are motoring (eg. winders) and some are regenerating (eg. unwinders). In these
situations it is convenient to connect the drives on a common DC link.
In this system, the 4-Q Regen drive supplies the motoring and regenerating requirement of the load.
Additional external equipment required by the 4-Q Regen drive includes :
 EMC Filter
 AC Line Fuses
 DC Link Fuses
No extra hardware is required to detect the rotation, frequency and phase of the mains supply. Also, no
dynamic braking resistor is required.
The 4-Q Regen drive draws sinusoidal, unity power factor current from the supply and only has to be rated
for either the power consumed or supplied by the system, or by the system braking requirements, whichever
is the larger.
Dynamic Braking (eg. for Emergency Stopping purposes) can still be used in this control mode if required.
