Chapter 4 Connect the Kinetix 350 Drive System
Single-phase Power Wired to Single-phase Drives
These examples illustrate grounded single-phase power that is wired to single-
phase Kinetix 350 drives when phase-to-phase voltage is within drive
specifications.
Figure 30 - Single-phase Grounded Power Configurations
(1) This configuration applies to voltage-doubler operation for 2097-V31PRx-LM drives.
If you reduce transformer output, the motor speed is reduced. Feeder and
branch short circuit protection is not illustrated.
Voltage Doubler Operation
You can wire the 2097-V31PRx-LM drives with 120V input voltage and
achieve twice the output voltage. To use the voltage-doubler circuit, connect
the 120V single-phase input power to the IPD-L1 and IPD-N terminals.
For Kinetix 350 drive power specifications, refer to Kinetix Servo Drives
Specifications Technical Data, publication KNX-TD003
. For Kinetix 350
drive input wiring diagrams, refer to Power Wiring Examples on page 131
.
IMPORTANT The 2097-V32PRx-LM models have integrated AC line filters and do not
require the AC line filter that is shown in this diagram.
