22022 [Channel %1: ] Block %2 spindle %3 gear stage %4 is expected for axis

mode.

Parameters: %1 = Channel number

%2 = Block number, label

%3 = Spindle

%4 = Gear stage

Definitions: The gear stage required for axis mode has not been installed.

A gear stage has been configured in MR35014 $MA_GEAR_STEP_USED_IN_AXISMODE, in which

the spindle is to be in axis mode. This gear stage is checked whenever the spindle is switched into

axis mode. The configured gear stage is compared with the gear stage output by the PLC (NC/PLC

interface signal V380x 2000.0 - .2 (Actual gear stage A through C)).

This alarm will be output if the gear stages are not the same.

Reaction: Interface signals are set.

Alarm display.

Remedy: Program M70 before the switch to axis mode. The gear stage configured in MD35014

$MA_GEAR_STEP_USED_IN_AXISMODE is then automatically loaded.

No gear stage change is required if the configured gear stage is aleady active. M40 remains active

beyond the gear stage change.

Consider MD20094 $MC_SPIND_RIGID_TAPPING_M_NR.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

22040 [Channel %1: ] Block %3 spindle %2 is not referenced with zero marker

Parameters: %1 = Channel number

%2 = Axis name, spindle number

%3 = Block number, label

Definitions: The current position is not referenced with the measuring system position although reference is made

to it.

Reaction: Alarm display.

Remedy: Correct NC part program. Create the zero mark synchronization by positioning, by rotation (at least 1

revolution) in speed control mode or G74 before switching the alarm generating function on.

If this has been intentionally programmed, the alarm can be suppressed in the cyclic check with posi-

tion control already enabled by means of MD11410 $MN_SUPPRESS_ALARM_MASK Bit21 = 1.

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

22050 [Channel %1: ] Block %3 spindle %2 no transition from speed control

mode to position control mode

Parameters: %1 = Channel number

%2 = Axis name, spindle number

%3 = Block number, label

Definitions: - An oriented spindle stop (SPOS/SPOSA) has been programmed or the position control of the spindle

was switched on with SPCON but no spindle encoder has been defined.

- When switching on the position control, the spindle speed is greater than the limiting speed of the

measuring system.

Reaction: NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Spindle without attached encoder: Any NC language elements requiring the encoder signals must not

be used.

Spindle with attached encoder: Enter the number of spindle encoders used in the MD30200

$MA_NUM_ENCS.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

22051 [Channel %1: ] Block %3 spindle %2 reference mark not found

Parameters: %1 = Channel number

%2 = Axis name, spindle number

%3 = Block number, label

1 2 ... 166 167 168 169 170 171 172 173 174 175 176 ... 339 340
