Chapter 2 Plan the Kinetix 5700 Drive System Installation
Refer to the Kinetix 5700, 5500, 5300, and 5100 Servo Drives Specifications
Technical Data, publication KNX-TD003
, for additional power specifications
for your 2198-Pxxx DC-bus power supply and 2198-RPxxx regenerative bus
supply.
24V Control Power Evaluation
The Kinetix 5700 drive system requires 24V DC input for its control circuitry.
Due to the 24V shared-bus connection system and the 24V current
requirements of the Kinetix 5700 drives, a thorough evaluation of control
power is required prior to implementation. Consider the following when
sizing such a system:
• Verify that the 24V DC power supply is capable of supplying the 24V
current requirements of your Kinetix 5700 drive system. See Calculate
24V DC Control Power Current Demand on page 378 to determine the
24V current requirements. For systems with a high 24V current demand,
consider the following:
- Install separate 24V power supplies for each cluster or change the
cluster configuration to more evenly divide the 24V current demand.
- Install separate 24V power supplies for each Bulletin 2198 power
supply and inverter.
• Verify that the wiring being used is capable of supplying the Kinetix 5700
drive system with a voltage within the 24V input-voltage range; 24V ±10%
(21.6…26.4V DC). Consider the following:
- Mount the 24V power supply as close to the Kinetix 5700 drive system
as possible to minimize input voltage drop.
- Install larger gauge wire, up to 4 mm
2
(12 AWG) and 6 mm
2
(10 AWG)
for 24V control power when using the CP connectors included with the
module; or use the 24V shared-bus connection system to lower the DC
wire resistance with up to 10 mm
2
(6 AWG) and result in a lower
voltage drop.

(1) Applies when DC-bus voltage regulation is enabled. If DC-bus voltage regulation is not enabled, then the input voltage range is 324….528V AC. For more information on these two modes of
operation, see DC-bus Voltage Regulation
on page 40.
IMPORTANT
The 24V current demand, wire gauge, and wire length all impact the
voltage drop across the wiring being used. For an example, see 24V DC
Voltage Drop Calculation Example on page 379.
