UKROBOTIC: there IS an unvalued cap in the DC servo circuit schematic that FU9 and FU10 feed - it has the 3.3K ohm bleeder resistor across it. FU9 and FU10 are rated at 25 amps each.
The cap is not huge electricaly - I think it is 40 or 50,000 uF but I don't recall anymore - sadly it is mouned in a way that you can NOT easily read the value on it and it is a major huge PITA to disassemble the P/S to read what the cap value is.
The servos are rated at something like 19-20 amps each if I recall.
Between the 3-6 feet of 16-18 gage interconet wire in the cabinet and anther 6-8 feet out to the servose, and the fuses, they seem to have the circuit pretty robust with regard to inrush issues.
We've never popped a DC servo fuse and we had the servos go up against the limits a number of times. BTW, we suspect that the DC servos may have never drew peak current because of soft current limits that were programmed into the sytem by the software. |
