Hello guys,
I would need an advice to clear a doubt i have.
In the next few months we will probably acquire a KR10 R1420 Cybertech NANO, paired with a KRC4 Smallsize controller
There won't be any additional axes, only the robot itself.
I downloaded all documentation I could, and the KRC4 Smallsize specification manual states this power requirements:
Rated supply voltage AC 3x380 V, AC 3x400 V, AC 3x440 V or AC 3x480 V
Direct connection with grounded neutral
Rated supply voltage tolerance ±10%
Rated connected load 3.30 kVA
Short circuit current rating 5 kA
System impedance ≤ 300 mΩ
Ground leakage current -
Mains-side fusing 3x 32 A, slow-blowing
Mains-side fusing without drive box 3x 16 A, slow-blowing
Mains frequency 49 ... 61 Hz
So far so good, except that the total power rating of the 6 Robot motors is around 5.11 KW
I'm quite sure that the Robot will never use all the motors at maximum power at the same time, but anyway I don't understand why the controller seems "underpowered" with only 3.3 KVA
How much power I have to guarantee in order to be sure that the robot will work properly?
Thank You for your time
