Fuji Frenic 5000g V2

Does any body have ANY documentation on this drive? I have many in my area and retrofitting is fast becomming a requirement. However without any I/O information it's kinda hard so any help would be great.
Thanks

Delta or Wye

I have a motor from China 12 lead and the label says it can be connected either low or high voltage 220/440 in Delta or Wye. So there are 4 different options of which 2 are dictated bye supply voltage. So we are left with delta or Wye for running. What are the characteristics of the 2 connections? The application is a spindle motor on a machine tool.

Starting resistance

I have a wound rotor motor (200hp) with resistors for starting etc. There are 6 resistors 1 stays in circuit all the time and one is stated to be for braking. This one is the last in the circuit and is jumped across one side to complete the circuit. The problem I have is that the other 4 resistors are not equal steps. There is 1 large step maybe 60% then a 20% a 10% and another 10%. My question is should the 60% be the first step or the last step? The application is a plate roll. We have replaced all the original controls with a PLC. We got this machine in pieces and most of the electrical panel was missing. the original prints do not show different resistors just resistors.

Running in Star

I have a situation where I am trying to run a star delta motor. When the Delta contactor kicks in (open transition mechanically interlocked) the breaker trips. I know that I am close to the limit on the breaker so I want to run the motor in Star for the purpose of testing lubrication and noise. No load will be placed on the motor other than the headstock of the machine 96" Blanchard grinder. will this damaged the motor?

Speed control

How does one control the speed of a wound rotor indution motor and how does this speed change affect the torque of the motor?
The motor in question is a 220HP.
