Over-Travel - Siemens SINAMICS V90 Operating Instructions Manual

Control functions
7.2 General functions
Note
After modifying parameter p29001, you must save the parameter and then restart the drive
to ensure normal operation. In this case, you must perform referencing again because the
reference point will be lost after p29001 changes.
7.2.3

Over-travel

When the servo motor travels over distance limit, limit switch is turned on and servo motor
then has an emergency stop.
Travel limit signals (CWL/CCWL)
NOTICE
Some important information about the travel limit signals (CWL/CCWL)
• Both of the signals must be at the high level when the servo drive is powered on.
• When the drive is under the S or T control mode, operation is possible after you
• In all the modes, signal CWL/CCWL can be responded, which means when F7492 or
138
acknowledge the fault; while when the drive is under the PTI or IPos control mode,
operation is possible only when both CWL and CCWL are at the high level (logic 1) after
you acknowledge the fault.
F7491 happens, the motor can run over the travel limit if the fault is acknowledged.
– For a positive traversing direction, if the STOP cam plus is reached, F7492 will
happen. To clear the fault, acknowledge it with RESET, and then leave away from
the STOP cam plus in the negative traversing direction to return the axis to the valid
traversing range.
– For a negative traversing direction, if the STOP cam minus is reached, F7491 will
happen. To clear the fault, acknowledge it with RESET, and then leave away from
the STOP cam minus in the positive traversing direction to return the axis to the valid
traversing range.
