SINUMERIK 840D/SIMODRIVE 611 digital, HLA Module (FBHLA) - 10.03 Edition
Axis %1, drive %2 No external voltage supply to valve
%1 = NC axis number
%2 = drive number
The external 26.5 V supply (X431: P24, M24) is monitored for violation of a
lower limit in the control.
Cause: Voltage dips or voltage outside the permissible range.
Mode group not ready.
Under certain circumstances it can be switched over across the entire channel
via MD.
Channel not ready.
NC stopped in response to alarm.
NC start disable.
The NC switches to follow-up mode.
Alarm display.
Interface signals are set.
Check the following monitoring criteria:
- Voltage range (average) 26.0 V to 27.0 V
- Ripple factor 240 mVp-p
- No voltage dips
Axis %1, drive %2 valve is not responding
%1 = NC axis number
%2 = drive number
The valve is not responding to the valve slide setpoint.
Cause: Valve is not connected or has no valve spool checkback signal.
Mode group not ready.
Under certain circumstances it can be switched over across the entire channel
via MD.
Channel not ready.
NC stopped in response to alarm.
NC start disable.
The NC switches to follow-up mode.
Alarm display.
Interface signals are set.
Valve without valve spool checkback: MD 5530: Reset bit 2;
Check valve connection.
Cancel alarm in all channels of this mode group by pressing RESET. Restart
part program.
Axis %1, drive %2 velocity controller at limit
%1 = NC axis number
%2 = drive number
The speed controller output has been at its limit for an impermissibly long time
(MD 5605: SPEEDCTRL_LIMIT_TIME (speed controller limit threshold).
