Problem- HELP!! PLEASE

[BALLISTIKIDD]

I DO ONE OFF PROTOTYPING AND NOW AT A STAND STILL, not sure where to start with this.
No alarms on the pc controller. Just a flashing alarm on the servo amplifier.
SONY NU20/30CONTROLLER
MITSUBISHI SERVO MR-J2-20A1,

SO WHAT DOES THIS MEAN, DO I NEED TO REPLACE THE SERVO
AMP, OR? HOW WOULD I RESET THE PARMETERS, where to start.
GETTING ALARM A.37 on the servo amp

MITSUBISHI WEBSITE SAYS
A. 37 Parameter/ error Parameter
setting is wrong.
1. Servo amplifier fault caused the
parameter setting to be rewritten.
Change the servo amplifier.
2. Regenerative brake option not
used with servo amplifier was
selected in parameter No. 0.
Set parameter
No. 0 correctly

First re load the servo Drive parameters, check the any mechanical jamming etc in the related axis , If you are applying any additional brake check that also and if problem persist feel free to communicate over prabhatmishra@gmx.com
