STAT

Description

The STAT command provides a 16-bit status word in hexadecimal format (Hxxxx).

Bit Value Interpretation
0 0x0001 =0 if output stage is enabled
=1 output stage disabled
1 0x0002 =0 if controller is ready for operation (BTB)
=1 fault present
2 0x0004 reserve
3 0x0008 =1 if service function is active
=0 no service function active
4 0x0004 reserve
5 0x0020 =1 after a hardware reset, is cancelled by CLRHR
6 0x0040 =1 configuration variable was altered (SAVE and COLDSTART)
=0 no configuration variable altered
7 0x0080 =1 safety relay is active (AS-Option)
=0 safety relay is not active
8 0x0100 =1 discrepancy between RAM and EEPROM parameters (cancelled by SAVE command).
=0 RAM and EEPROM parameters are the same
9 0x0200 =1 slot-expansion card is available
=0 slot-expansion card is not available
10 0x0400 =1 RAM parameter modified (cancelled by DUMP command)
=0 no change in RAM parameters since the last DUMP.
11...15 Reserve

Bits 5, 6, 8 and 10 are used for an external signal that internal parameters have been changed

Bit 5 hardware reset
Bit 5 is set if the parameters are copied from the serial EEPROM to the RAM (this happens after a hardware reset of a LOAD command). If this bit is set, all the parameters should be requested by the parameterization software (DUMP command) and bit 5 should be cancelled by the CLRHR command.

Bit 6 configuration variable was altered
Any alteration of a configuration variable (a variable that makes it necessary to recompile the macro, i.e. to reset the amplifier) means that this bit will be set to 1. If this bit is set, the parameterization software should generate a SAVE / COLDSTART command (controller reset) at a suitable moment. Bit 6 is only cancelled by a hardware reset (COLDSTART).

Bit 8 discrepancy between EEPROM and RAM parameters
Any alteration of a RAM parameter means that this bit is set to 1. If this bit is set, the parameterization software should generate a SAVE command (save the data in the EEPROM) at a suitable moment (e.g. on exiting the program). This bit is cancelled by a SAVE command.

Bit 10 RAM parameters modified
Any alteration of a RAM parameter through a parameterization channel other than the RS232 means that this bit is set to 1. If this bit is set, the parameterization software should generate a DUMP command (read all data) at a suitable moment. This bit is cancelled by a DUMP command.
