310709 Axis %1 drive %2 error in piston diameter or piston rod diameter
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The piston diameter in drive MD 5131: CYLINDER_PISTON_DIAMETER is less than or equal to zero
or the piston rod diameter in drive MD 5132: CYLINDER_PISTON_ROD_A_DIAMETER is greater
than the piston diameter in drive MD 5131: CYLINDER_PISTON_DIAMETER or the piston rod
diameter in drive MD 5133: CYLINDER_PISTON_ROD_B_DIAMETER is greater than the piston
diameter in drive MD 5131: CYLINDER_PISTON_DIAMETER.
Reaction: NC not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Enter a valid piston diameter in drive MD 5131: CYLINDER_PISTON_DIAMETER (0 < D <= 500mm).
or Enter a piston rod diameter in drive MD 5132: CYLINDER_PISTON_ROD_A_DIAMETER which is
less than the piston diameter in drive MD 5131: CYLINDER_PISTON_DIAMETER or Enter a piston
rod diameter in drive MD 5133: CYLINDER_PISTON_ROD_B_DIAMETER which is less than the
piston diameter in drive MD 5131: CYLINDER_PISTON_DIAMETER.
Program Switch control OFF - ON.
Continuation:
310710 Axis %1 drive %2 distance-coded scale incorrectly parameterized
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: If a distance-coded scale is selected (MD 5011 bit 7=1) a length measuring system must also be
configured (MD 5011 bit 4=1).
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Check and, if necessary, correct MD 5011: ACTUAL_VALUE_CONFIG (actual value sensing
configuration).
Program Switch control OFF - ON.
Continuation:
310750 Axis %1 drive %2 feedforward gain too high
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The feedforward control gain is calculated from the reciprocal of the gain in drive MD 5435:
CONTROLLED_SYSTEM_GAIN.
Reaction: NC not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy: Increase the speed controller cycle time in MD 5001: SPEEDCTRL_CYCLE_TIME.
Reduce the force controller feedforward factor in MD 5247: FORCE_FFW_WEIGHT.
Increase the gain in MD 5435: CONTROLED_SYSTEM_GAIN.
Program Clear alarm with the RESET key in all channels. Restart part program.
