Description of function
Signal CWL functions as the clockwise travel limit while the signal CCWL functions as the counter-
clockwise travel limit. Both of them are level and edge sensitive signals.
Table 9-9 CWL and CCWL signals overview
Signal
type
Signal name Setting Description
DI CWL Falling edge
(1 → 0)
The servo motor has travelled to the clockwise travel limit and has a quick stop
after that.
DI CCWL
Falling edge
(1 → 0)
The servo motor has travelled to the counterclockwise travel limit and has a
quick stop af
ter that.

In S, T, or Fast PTI control mode, the motor rotates properly after you do as follows:
• When F52961 is triggered af
ter the STOP cam plus is reached in a positive traversing
direction, acknowledge the fault using the RESET signal, and then move the axis away from
the STOP cam plus in a negative traversing direction to return it to a position within the valid
traversing range.
• When F52960 is triggered after the STOP cam minus is reached in a negative traversing
direction, acknowledge the fault using the RESET signal, and then move the axis away from
the STOP cam minus in a positive traversing direction to return it to a position within the valid
traversing range.
WARNING
Danger to life or malfunctions of the machine due to the motor travelling over the
dis
tance limit
In T contr
ol mode, the motor travels over the distance limit if you only acknowledge the fault
without returning the axis to a position within the valid traversing range.
In S control mode, the motor travels over the distance limit if you only acknowledge the fault
without returning the axis to a position within the valid traversing range while signal CWL or
CCWL becomes from a low level (logic 0) to a high level (logic 1).
• Acknowledge the fault, and then return the axis to a position within the valid traversing
range to prevent the motor from travelling over the distance limit.
