BRAKE CONTROL SYSTEM FOR GRAVITY SHAFTS. |
摘要 |
<p>The stop of control for the gravity shafts is notified from CNC to PC (programmable controller) (S1). PC sends a signal to the machine side to operate the brake (S3). After a predetermined brake operation completion time has passed, CNC interrupts the exciting current from flowing to the servo motor (S7). The predetermined time is slightly longer than the time of from a moment at which CNC notified the stop of control of the servo motor to a moment at which the brake locks the gravity shaft.</p> |
