7.25 Soft limit setting (Fn305)
Soft limit setting means that the left and right limit positions are limited by the internal single and multi-turn values of the
absolute encoder in the absence of an external limit switch.
CAUTION
●
Please set the appropriate speed value.
● Please ensure that it is within the operating range of the machinery.
● Make sure the soft limit switch function is not turned on (Pn00A.W = 0).
(1) Precautions for basic settings (initialization)
To perform the soft limit setting operation, the following must be verified.
● The parameter
prohibit writing function (Fn010) is not set to "prohibit writing".
● Main circuit power ON.
●
No alarms have occurred.
● Servo is OFF.
●
The encoder is a multi-turn absolute encoder
.
