2 Overtemperature Acknowledgement key

POWER ON Cyclic

The second temperature monitoring threshold has been triggered because the ambient temperature is too high. NC program is not interrupted.

Safe functioning of the hardware can no longer be guaranteed, serious damage to hardware may result. Processing is not interrupted directly. A contact is opened on the CSB which the NC user must use to take the appropriate measures.

A low temperature level will eliminate the error. Switch off control (hardware damage possible).

3 Fan failure Acknowledgement key

POWER ON Cyclic

Fan monitoring is triggered because of incorrect fan functioning. Safe functioning of the hardware can no longer be guaranteed, serious damage to hardware may result.

Processing is not interrupted directly. A contact is opened on the CSB which the NC user must use to take the appropriate measures.

Eliminate the fan fault, e.g. by replacing the fan. Switch off control (hardware damage possible).

Machining standstill; interlocking of machining (NC Start); BAG–BB=0; NC–Ready=0

Error identifiers 01=Motion axis does not exist

A non–existing axis has been specified in the machine data 3800*, 3802*, 3804*. 02=Motion axes not in same mode group

Axes that are not in same mode group have been specified In the machine data 3800*, 3802*, 3804*. 03=Error in monitoring reference

The mutual deselection of the protection zone monitoring in the MD bits 38803+s*3 has not been executed correctly. Deselection of monitoring of protection zone 2 in the machine data of protection zone 1 causes the deselection of monitoring of protection zone 1 in the machine data of protection zone 2, i.e. deselection must always be carried out mutually.

06=Protection zones not defined in same plane The protection zone specified is 2–dimensional. It is related to another 2–dimensional protection zone, which is defined in another plane. But 2–dimensional protection zones that are in a monitoring relation must lie in the same plane.

1st possibility: The plane of the protection zone defined in the machine data 3812*, 3814*, 3816* is not identical with the planes of the other protection zones to be monitored.

2nd possibility: The protection zone should not monitor the protection zones in other planes, i.e. the protection zone relation must be corrected in the machine data bits 38803 – 38815 (monitoring relation).

The comparison of both monitoring channels has uncovered a difference between the input data or the monitoring results. One of the monitoring functions is no longer operating reliably, i.e. safe monitored operation is no longer possible.

Find the difference between the monitoring channels. The error code that indicates the cause appears in the following machine data:

on 840C MD 301: diagnostics for STOP F (SI service display) on 611D MD 1395: diagnostics for STOP F (SI drive display) The meaning of the error code can be found in the error code table for STOP F on the 840C. It is possible that the safety–related machine data are no longer identical (load them again if necessary) or that the SGEs do not have the same signal level (measure again or check in the SI service display). If no such error is found, an error may have occurred in the CPU, such as a corrupt memory cell. This error can be transient (remedied by POWER ON) or permanent (reoccurs after POWER ON, in this case replace the hardware).

Remedy the error, and press the RESET key. The program is aborted. If safe monitoring was active, STOP B was also initiated automatically. In this case, it is necessary to switch the control of f and on (POWER ON).

The data transfer of the SGEs/SGAs between PLC

and drive is guaranteed by a checksum. In the

event of an error, the calculated checksum does

not coincide with the transferred checksum. If the

stop is released by the drive, either the PLC or the
