Hello,
We have CINCINNAT MILACRON machine horizontal centers T30 with ACRAMATIC 950MC computer numerical control end

Servo drive SIEMENS model 6SC61 (4 axis).We had a power outage and after turn ON the control and hydraulics all axis moves in one time with various speed, without command.

I checked cables between motors and PWM, power output cables, cables for rotor position and tacho signals I doing commissioning by battery box but

drives runaway. I tried to adjusted drift but nothing. In this time touch pads for select axis is inhibit (power feed panel); just X touch pad is illuminated but not work.

On the power feed panel have illuminated just X, CONT, 100% touch pads LED’s all the time.

Can you help me please?



Thanks!
