Description of parameters

Parameters for motion monitoring functions
p9500 SI motion, monitoring clock cycle
Sets the monitoring clock cycle for safety motion monitoring functions.
Units: Default value:
ms 12
Using p9500, the monitoring clock cycle for safety-relevant operation with a higher-
level control is defined. p9500 must be an integer multiple of the position controller
clock cycle. If a value is entered into p9500 that is not an integer multiple of the
position controller clock cycle, then the value entered is rounded-off to the next
multiple (integer multiple) of the position controller clock cycle and Fault F01652
("SI CU:Monitoring clock cycle not permissible") is output with fault value 101.
Each time that a new connection is established for the clock-cycle synchronous
PROFIBUS, the PROFIBUS master can specify a new position controller clock
cycle; this is the reason that the check "p9500 multiple integer of the position con-
troller clock cycle" is repeated. Fault F01652 is output if an error occurs.
The Safety Integrated monitoring clock cycle is, just like all other SI drive parame-
ters, a drive-specific monitoring clock cycle. However, different SI monitoring clock
cycles within a drive system are not supported.
