SINUMERIK 802D sl, Diagnostics Manual, 06/2007Edition

26001 Axis %1 parameterization error: friction compensation

Parameters: %1 = axis name, spindle number

Definitions: The parameterization of the adaptation characteristic in the quadrant error compensation is not

allowed because acceleration value 2 (MD 32560 FRICT_COMP_ACCEL2) is not between accelera-

tion value 1 (MD 32550 FRICT_COMP_ACCEL1) and acceleration value 3 (MD 32570

FRICT_COMP_ACCEL3).

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.

Check the setting parameters of the quadrant error compensation (friction compensation), if neces-

sary switch off the compensation with MD 32500 FRICT_COMP_ENABLE.

Program Con-

tinuation:

Teileprogramm neu starten.Clear alarm with the RESET key in all channels of this mode group.

Restart part program.

26002 Axis %1 encoder %2 parameterization error: number of encoder marks

Parameters: %1 = axis name, spindle number

%2 = encoder number

Definitions: Rotary measuring system (MD 31000 ENC_IS_LINEAR[] == FALSE)

The number of encoder marks set in MD 31020 ENC_RESOL[] does not correspond to the value in

the drive machine data MD1005 or zero has been entered in one of the two machine data.

Absolute measuring system with EnDat interface

(MD 30240 ENC_TYPE[] == 4)

On absolute encoders, the resolution of the incremental and absolute track supplied by the drive is

also checked for consistency.

Motor measuring system: MD1005, MD1022

Direct measuring system: MD1007, MD1032

The two drive machine data must have a defined relation to one another. If the conditions listed below

are not fulfilled, an alarm is output.

2.1 Rotary measuring system (MD 31000 ENC_IS_LINEAR[] == FALSE)

MD1022/MD1005 == 4 * n [n=1,2,3...] (motor measuring system)

MD1032/MD1007 == 4 * n [n=1,2,3...] (Direct measuring system)

2.2 Linear measuring system (MD 31000 ENC_IS_LINEAR[] == TRUE)

MD1005/MD1022 == 4 * n [n=1,2,3...] (Motor measuring system)

MD1007/MD1032 == 4 * n [n=1,2,3...] (Direct measuring system)

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.

Compare machine data

For absolute encoders, pending drive alarms indicating encoder problems should be evaluated, if nec-

essary. They could be the cause of incorrect entries in MD1022/MD1032 which are read out of the

encoder by the drive.

Program Con-

tinuation:

Switch control OFF - ON.
