2-184

SINUMERIK 802D sl, Diagnostics Manual, 06/2009

NC Stop on alarm.

Channel not ready.

Remedy: Determine the leadscrew pitch (specify the machine manufacturer or pitch measurement with spindle

cover removed) and enter it in the MD31030: $MA_LEADSCREW_PITCH (mostly 10 or 5 mm/rev.).

Program Con-

tinuation:

Switch control OFF - ON.

26004 Axis %1 encoder %2 parameterization error: grid point distance with

linear encoders

Parameters: %1 = Axis name, spindle number

%2 = Encoder number

Definitions: The scale division of the linear scale set in the axis-specific MD31010

$MA_ENC_GRID_POINT_DIST is zero or differs from the corresponding drive parameters. For a bet-

ter understanding of the interrelations see the explanations for alarm 26002, which refer to rotatory

encoders.

The alarm can be reprogrammed in the MD11412 $MN_ALARM_REACTION_CHAN_NOREADY

(channel not ready).

Reaction: Mode group 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: Please inform the authorized personnel/service department.

Enter the encoder grid point distance according to the data given by the machine (or measuring

device) manufacturer in the MD31010 $MA_ENC_GRID_POINT_DIST.

Program Con-

tinuation:

Switch control OFF - ON.

26005 Axis %1 parameterization error: output rating

Parameters: %1 = Axis name, spindle number

Definitions: For analog drives:

The output evaluation of the analog speed setpoint set in the MD32250 $MA_RATED_OUTVAL or in

MD 32260 $MA_RATED_VELO is zero.

For PROFIdrive drives: (ADI4, SIMODRIVE 611U, SINAMICS):

The effective output evaluation of the speed setpoint interface is zero:

b. The corresponding drive-side standardizing parameter is zero, invalid or unreadable/unavailable

although an automatic interface scaling adjustment has been selected on account of MD32250

$MA_RATED_OUTVAL=0.

The drive parameter defining the standard is not determined by PROFIdrive, but is specific to the man-

ufacturer (see the relevant drive documentation: For SIMODRIVE 611U: p880; for SINAMICS: p2000).

The alarm can be reprogrammed in the MD11412 $MN_ALARM_REACTION_CHAN_NOREADY

(channel not ready).

Reaction: Mode group 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: Please inform the authorized personnel/service department. The nominal output voltage in [%] of the

maximum setpoint value (10 V) is entered in the MD32250 $MA_RATED_OUTVAL, at which the rated

motor speed in [degrees/s] is to be reached (MD32260 $MA_RATED_VELO).

Program Con-

tinuation:

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