The drive provides two possibilities of determining and monitoring a
limitation of the working range (travel range):
• monitoring position limit values (software limit switch)
Monitoring the motor position for exceeding one of the two position
limit values (positive/negative → S-0-0049/S-0-0050) by the homed
actual position value (S-0-0403), i.e. value related to the machine zero
point.
• monitoring travel range limit switches
Monitoring for activation of one of the two travel range limit switches
(Limit+, Limit-) that are connected to the digital inputs of the drive.
Note:
The functionality of the travel range limit switches is only
guaranteed if the respective digital inputs have been
configured for this purpose!
See "Digital Inputs/Outputs" in chapter "Extended Drive
Functions"

• signal behavior of travel range limit switches (N/C and N/O) can be set
• travel range limit switches activated via parameter
• reaction (error/warning) when exceeding travel range can be set
• status display of travel range limit switches
• command values monitored for validity when limit switch activated
• travel range limit switches evaluated and position limit value monitor
