mode Effect:
The axis movement is inhibited.
A167 The "start" [STA] control signal was activated
in MDI mode without initially transferring a
No velocity has been velocity value to the selected MDI block.
programmed in MDI
mode Effect:
The axis movement is inhibited.
A168 G91 (incremental dimensions) was defined in
the MDI block as the 1st G function for the
G91 not allowed with MDI on-the-fly function.
MDI on the fly
Effect:
The axis movement is inhibited or stopped via
the deceleration ramp.
A169 - Control signal "reset technology" [RST]
activated
Start conditions for
flying MDI do not exist - Control signal "follow-up mode" [FUM]
activated
Effect:
The "MDI on-the-fly" function is not executed.
A170 An NC block was started in single-block mode
although a block has not yet been transferred.
Single block mode
block does not exist Effect:
NC block execution is inhibited.
A172 The program number specified in [PROG_NO]
for automatic mode is not stored in the
Program with this memory of the technology.
number does not exist
Effect:
NC program execution is inhibited.
A173 The program number specified in [PROG_NO]
for automatic mode is not allowed.
Program number not
allowed Effect:
NC program execution is inhibited.
A174 The program number [PROG_NO] was
changed while the program was running.
Program number
changed during Effect:
traversing NC program execution is aborted and the axis
or axes are brought to a standstill via the
deceleration ramp.
A175 The decoded NC block is not terminated with
the following block identifier "0".
No block end
programmed 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.
A177 The program number for the main program
(level 0), which was transferred with the block
Prog. number of block search function, does not exist.

Use the correct sequence: data transfer
followed by axis start.
Use the correct sequence: data transfer
followed by axis start.
The MDI on-the-fly function only allows G90
(absolute dimensions) as the 1st G function.
Ensure that the control signals are activated
correctly.
Transfer the block.
- Transfer the program to the technology.
- Select the correct program number.
The permissible range for program numbers is
between 1 and 200.
The program number must not be changed
while the program is running.
Correct the block.
The last block in the sequence must contain
the following block identifier "0".
Specify an existing main program number.
