Kinetix 6000M System Sizing Appendix D
Step 4: Estimate the IAM control power load current and the power
dissipation for each IPIM module based on the total IDM unit
control power load.
See the Kinetix Rotary Motion Specifications Technical Data, publication
GMC-TD001 , for specifications on IPIM module dissipation and IPIM module
control power loading. This information is also shown below. The table below
contains equations that can be used to calculate the IAM control power load for
each IPIM module and the heat dissipation for each IPIM module. The input
value (x) is the total IDM unit control power load current (as a percentage)
provided by the IPIM module. This value (in amps) was calculated in step 2. The
value from step 2 must be divided by the rated IPIM module control power load
current, (6.5 A).
Make these calculations for all IPIM modules connected to the power rail. The
control power load current values will be used to confirm the system sizing for the
IAM, power rail and LIM in a later step.
Example
Using the equations provided, determine values for:
• Control power = 120V AC, 60 Hz
• IDM control power load current = 2.64 A or 40.6%
Result is an IAM control power load current of 2.32 A and an IPIM module heat
dissipation value of 29 W.

IAM Control Power Current (1)
(1) Y = IAM control power current; x = Total IDM unit control power load current percentage (value from step 2).
IPIM Heat Dissipation (2)
(2) Y = IPIM module heat dissipation from control power load; x = Total IDM unit control power load current percentage (value from
step 2).
120V AC, 50 Hz Y = 3.91x + 0.77 Y = 23.76x 2 + 20.73x + 16.54
240V AC, 50 Hz Y = 2.39x + 0.60 Y = 18.56x 2 + 30.19x + 27.41
120V AC, 60 Hz Y = 3.72x + 0.83 Y = 14.57x 2 + 11.40x + 20.01
240V AC, 60 Hz Y = 2.45x + 0.61 Y = 19.63x 2 + 43.22x + 28.75
