Motor Movement Range Setting
If the motor travels exceeding the motor working range which is set with Pr5.14 “Motor working range setup”
in addition to the position command input range, the software limit protection will make an alarm stop.
The use of this function will prevent collision with the machine end caused by motor oscillation.
(1) Scope of application
□This function is applicable only when the following conditions are satisfied:
Conditions for operating motor working range function
Action state
In Servo On status.
Factors other than control parameters such as the deviation counter clear and com-
mand pulse inhibition inputs and the torque limit are appropriately configured and do
not cause any problem in normal motor rotation.
(2) Cautions
Note that this function does not provide protection against abnormal position commands
If software limit protection works, the device slows down and halts in accordance with Pr5.10 “Sequence
at alarm”.
Some loads may contact an edge of device and cause damage. Specify a range for Pr5.14 in consideration of
slowing down operations.
The software limit protection is invalid during the trial run performed via the front monitor and when the
frequency characteristics function is used through the communication.
