Cause
Counter-measure
A166
No position has been
programmed in MDI
mode
The "start" [STA] control signal was activated
in MDI mode without initially transferring a
positional value to the selected MDI block.
Effect:
The axis movement is inhibited.
Use the correct sequence: data transfer
followed by axis start.
A167
No velocity has been
programmed in MDI
mode
The "start" [STA] control signal was activated
in MDI mode without initially transferring a
velocity value to the selected MDI block.
Effect:
The axis movement is inhibited.
Use the correct sequence: data transfer
followed by axis start.
A168
G91 not allowed with
MDI on the fly
G91 (incremental dimensions) was defined in
the MDI block as the 1st G function for the
MDI on-the-fly function.
Effect:
The axis movement is inhibited or stopped via
the deceleration ramp.
The MDI on-the-fly function only allows G90
(absolute dimensions) as the 1st G function.
A169
Start conditions for
flying MDI do not exist
- Control signal "reset technology" [RST]
activated
- Control signal "follow-up mode" [FUM]
activated
Effect:
The "MDI on-the-fly" function is not executed.
Ensure that the control signals are activated
correctly.
A170
Single block mode
block does not exist
An NC block was started in single-block mode
although a block has not yet been transferred.
Effect:
NC block execution is inhibited.
Transfer the block.
A172
Program with this
number does not exist
The program number specified in [PROG_NO]
for automatic mode is not stored in the
memory of the technology.
Effect:
NC program execution is inhibited.
- Transfer the program to the technology.
- Select the correct program number.
A173
Program number not
allowed
The program number specified in [PROG_NO]
for automatic mode is not allowed.
Effect:
NC program execution is inhibited.
The permissible range for program numbers is
between 1 and 200.
A174
Program number
changed during
traversing
The program number [PROG_NO] was
changed while the program was running.
Effect:
NC program execution is aborted and the axis
or axes are brought to a standstill via the
deceleration ramp.
The program number must not be changed
while the program is running.
A175
No block end
programmed
The decoded NC block is not terminated with
the following block identifier "0".
You can use the "output actual values -
decoder error location" task to read out the
program number and block number where the
block decoder detected an error.
Effect:
NC program execution is inhibited or aborted.
Moving axes are stopped via the deceleration
ramp.
Correct the block.
The last block in the sequence must contain
the following block identifier "0".
A177
Prog. number of block
search forwd. does not
exist
The program number for the main program
(level 0), which was transferred with the block
search function, does not exist.
Effect:
NC program execution is inhibited.
Specify an existing main program number.
