Sinumerik Alarm 310608 Axis %1 drive %2 speed controller at limit

Sinumerik Alarm 310608 Axis %1 drive %2 speed controller at limit

Parameters:
%1 = NC axis number
%2 = Drive number

Definitions:
The speed controller output is lying for an impermissibly long time at its limit (MD 5605: $MD_SPEEDCTRL_LIMIT_TIME and MD 1606: (speed controller limit threshold). The monitoring system is only active when the speed setpoint is below the speed threshold in MD 5606: SPEEDCTRL_LIMIT_THRESHOLD (speed controller limit threshold).

Reactions:
– The NC switches to follow-up mode.
– Mode group not ready.
– Channel not ready.
– NC Start disable in this channel.
– Interface signals are set.
– Alarm display.
– NC Stop on alarm.
– Channel not ready.

Remedy:
• Is the drive blocked?
• Is the encoder connected? (check the encoder cable)
• Check the shield connection on the encoder cable
• Encoder defective?
• Check the encoder resolution
• The Uce monitoring circuit has been activated (perform a reset by switching the power supply off and on again).
• Replace the control module.
• Modify MD 5605: SPEEDCTRL_LIMIT_TIME and MD 5606: SPEEDCTRL_LIMIT_THRESHOLD in accordance with the mechanical and dynamic features of the axis.

Program Continuation:
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
