8.1-14 Compendium Motion Control SIMOVERT MASTERDRIVES
The parameter ID (PKE) is always one word (16-bit quantity).
Bits 0 to 10 (PNU), together with bit 15 of the parameter index, make up
the number of the desired parameter (see parameter list).
Number PKE: Bits 0 to 10
(PNU)
Index: Bit 15
1 - 999 1 - 999 0 Basic unit
2000 - 2999 0 - 999 1 Basic unit
1000 - 1999 1000 - 1999 0 Technology module
3000 - 3999 1000 - 1999 1 Technology module
Bit 11 (SPM) is the toggle for parameter-change reports.
MASTERDRIVES do not support parameter change reports.
Bits 12 to 15 (AK) contain the task or reply ID.
The task IDs are sent in the telegram from the master to the slave. The
meaning of the IDs is given in Table 8.1-5. Correspondingly, the reply
IDs are transferred at this position in the telegram from the slave to the
master (see Table 8.1-6). Depending on the task ID, only certain reply
IDs are possible. If the reply ID is 7 (task cannot be executed), then an
error number is entered in parameter value 2 (PWE2). The error
numbers are shown in Table 8.1-7.
