The Multiple Components in Parallel feature specifies the number
of Electrical and Mechanical components in parallel at each stage
in the Axis chain. Electrical components include Drives, Infeed,
Bleeder and Capacitor Modules. Mechanical components include
Motors, GearMotors, Transformations, Linear Actuators and Pumps.
One example is 1 Drive powering 2 Motors. Another is 2 Drives
powering 1 Motor. The rated values are multiplied by the number. So
if there are 2 Motors in parallel, the Motor's effective rated Max
and Cont Torque are 2x.
The number of Drives in an axis can be set to more than 1. The
"Number of Drives in Parallel" parameter can be set in a few places
including the Drive and Motor
Performance form and the Main form as shown
here.
By changing the number of Drives in Parallel to
2, the Inverter rated Peak & Cont Currents are
increased by 2x from 45 & 22.5A to 90 & 45A respectively.
The same goes for the Bus and Chopper rated values.
Number of External Bleeder Modules per Drive
External Bleeder Modules connected to a Drive's Chopper are a
special case, where the number of External Bleeders per
Drive is specified.
The default value is 1. Here we have 1 Drive
with 1 ExtBleeder per Drive as shown..
And here is 1 Drive with 2 ExtBleeders per
Drive as shown... note the Bleeder's rated Peak & Cont
power are 2x, and the Resistance is 1/2 because the bleeders are in
parallel.
Taking this another step, setting 2 Drives with
2 ExtBleeders per Drive results in 4 ExtBleeders in total. This is
because the number of External Bleeders is per
Drive. Therefore, the External Bleeder rated Peak
& Cont power are 4x and the Resistance is 1/4.
