5.3.4 Setting the Overtravel Signals
Polarity detection cannot start in overtravel state.
When using the overtravel function, connect the signal wires and use in base block
status. When not using the overtravel function, set the parameters Pn50A.3 to 8 (For-
ward run allowed) and Pn50B.0 to 8 (Reverse run allowed). The setting validation is
required to enable the settings.
5.3.5 Setting the Force Limits
To prevent danger during setup of the linear servomotor, the factory settings for the
forward force limit (Pn483) and reverse force limit (Pn484) parameters are set to a
small value (factory setting: 30%).
If the force limits are set after the steps described in 5.3.1 Setting and Checking the
Linear Scale Pitch and 5.3.2 Hall Sensor Selection, overrun will not occur. Increase
the value in the parameters up to the required force. Set the value to the maximum
value if no particular restricting conditions apply.
Note: If the force limit is set too high, polarity detection may not operate normally
