Hit250m mr-j2s-100a-s046 turret servo drive

Hi Everyone,
I have a lathe Hyundai HIT 250M with Mitsubishi Servo drive MR-J2S-100A-S046 that's dead. I Bought a refurbished one with same reference. But when installed it and want to enter parameters, it seems like it's arranged differently. So, i think that "maybe" the firmware is not the same. I tried to communicate with old one to get firmware version, but cannot make communication work. With the new one, the communication is ok.
I have the original parameter sheet of the servo unit but without the description of each parameter.
When i power on the machine, it gave no alarm at servo unit, but gave alarm on siemens screen.
Please can someone gave me help?
