I've recently brought a 2000 Biesse Rover 23 which I'm in the process of tearing down. I've already got a 4x8 joes style machine but the Rover dwarfs that machine.
The Biesse has Yaskawa SGDB drives and an old HSD motion controller.
I'll be installing a new controller and removing most of the pneumatics and I/O. I have no need for the boring head or the vacuum table.
I've got the tool changer servo and drive removed from the machine and setup on the bench. I've run through the test setup section of the manual but can't get the motor to jog.
I've set the memory switches for overtravel and enable. The digital user displays 'run' when the drive turns on. When I go into the ch-00 and enter jog mode I can change the motor to the on state but the up and down arrows don't jog the motor.

The red alarm LED is lit but I can't figure out how to clear it or get an error code.

Can anyone point me in the right direction?
