Output of status bits via the front plate
The status bits are output via the front plate using 2 hex values.
S16, S17
S16:
Bit Meaning
1 ="1":No fault
="0":errors E1 ... E57; the drive does not accept any positioning commands.
After "Power on", bit 1 remains at "0" until the self-test has been executed.
2 ="1":No warning
="0" Error E57
3 Machine zero has been approached
4 Ready for start
5 Programmed nominal position reached
6 Idle after stop
7, 8 Bit 7 Bit 8
0 0 after OUTPUT O0 = "0"
1 0 after OUTPUT O0 = "1"
0 1 after OUTPUT O0 = "2"
S17:
Bit Meaning when "1"
1 Password 302 active
2 Service password active
3
Command active; move commands (POSA, POSR; speed in speed control mode) are rejected using
E92.
4 Program memory running
5 Stop via input I6
6 reserved
7 RUN ("0" = OFF or switched off when error occurs)
8 ---
Bit sequence during transmission of S16 / S17:
Bit 1 is on the left (the transmission starts with bit 1)
E.g.: S17= "1000 0000" during ASCII transfer.
COMPAX front plate: display "01"
E.g.:
password 302 active S17 = 0x80 (if all other bits ="0").
Explanation of error history S18
The errors which occur are recorded by COMPAX in an 8-stage shift register. The entire contents of this
memory can be read using a status query. Once the error has been acknowledged, "99" is inserted. Once a
new error occurs, this is inserted in the shift memory.
When querying using S18, the contents of the shift register are output separated by spaces.
Once the unit is switched off, S18 is retained. If the unit is switched off while an error is present, a Power On
acknowledgement is created when the unit is switched on, i.e. a "98" is inserted in the shift memory.
Example:
S18C

Response: S018: 99 55 10 99 53 98 10 99C

The last error, an emergency stop (E55), has been acknowledged.
E10 occurred before this (E10 has not been acknowledged).
E53 has been acknowledged.
E10 has been acknowledged by Power on.
The error memory is completely reset to "00" by the reset parameter, i.e. "00" means no errors.
