SINUMERIK 802D sl, Diagnostics Manual, 06/2009

20007 [Channel %1: ] Axis %2 reference point approach requires 2 measuring

systems

Parameters: %1 = Channel number

%2 = Axis name, spindle number

Definitions: 2 encoders are needed for setting MD34200 $MA_ENC_REFP_MODE = 6!

Reaction: NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Please inform the authorized personnel/service department.

Modify reference mode MD34200 $MA_ENC_REFP_MODE or install and configure a second

encoder.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

20008 [Channel %1: ] Axis %2 reference point approach requires second

referenced measuring system

Parameters: %1 = Channel number

%2 = Axis name, spindle number

Definitions: When setting MD34200 $MA_ENC_REFP_MODE = 6 the 2nd encoder must first be referenced.

Reaction: NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Modify referencing mode MD34200 $MA_ENC_REFP_MODE or reference 2nd encoder.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

20050 [Channel %1: ] Axis %2 handwheel mode active

Parameters: %1 = Channel number

%2 = Axis name, spindle number

Definitions: The axes cannot be traversed in JOG mode using the traversing keys because traversing is still taking

place via the handwheel.

Reaction: Alarm display.

Remedy: Decide whether the axis is to be traversed by means of the direction keys or the handwheel. End hand-

wheel travel and delete the axial distance-to-go if necessary (NC/PLC interface signal V380x 0002.2

(Delete distance-to-go/Spindle reset)).

Program Con-

tinuation:

Alarm display showing cause of alarm disappears. No further operator action necessary.

20051 [Channel %1: ] Axis %2 handwheel mode not possible

Parameters: %1 = Channel number

%2 = Axis name, spindle number

Definitions: The axis is already traveling via the traversing keys, so handwheel mode is no longer possible.

Reaction: Alarm display.

Remedy: Decide whether the axis is to be traversed by means of the jog keys or via the handwheel.

Program Con-

tinuation:

Alarm display showing cause of alarm disappears. No further operator action necessary.

20052 [Channel %1: ] Axis %2 already active

Parameters: %1 = Channel number

%2 = Axis name, spindle number

Definitions: The axis is to traverse as a machine axis in JOG mode using the direction keys on the machine control

panel. However, this is not possible because:

1. It is already traversing as a geometry axis (through the channel-specific interface V3200 1000.7 /

0.6 (Traversing keys -/+) or V3200 1004.7 / 4.6 (Traversing keys -/+) or V3200 1008.7 / 8.6 (Traversing

keys -/+)) or

2. It is already traversing as a machine axis (through the axis-specific interface V380x 0004.7 / 4.6

(Traversing keys plus/minus)) or
