To use the overheat protection in a YASKAWA Linear Servomotor (SGLFW2), set Pn61A
to n.1.
An A.93B warning (Overheat Warning) will be detected if the overheat protection input
(TH) signal from the YASKAWA SGLFW2 Linear Servomotor exceeds the warning tem-
perature.
An A.862 alarm (Overheat Alarm) will be detected if the overheat protection input (TH)
signal from the YASKAWA SGLFW2 Linear Servomotor exceeds the alarm temperature.
– If the overheat protection input signal line is disconnected or short-
circuited, an A.862 alarm will occur.
– If you set Pn61A to n.  1 (Use overheat protection in the YAS-
KAWA Linear Servomotor), the parameters in the Servomotor are
enabled and the following parameters are disabled.
– Overheat Alarm Level (Pn61B)
– Overheat Warning Level (Pn61C)
– Overheat Alarm Filter Time (Pn61D)
Set Pn61A = n.X to 2 or 3 to use overheat protection for the machine.
Set the following parameters as required.

– When Pn61A is set to n.  2, an A.862 alarm will occur if the over-
heat protection input signal line is disconnected or short-circuited.
– When Pn61A is set to n.
 3, an A.862 alarm will not occur if the
overheat protection input signal line is disconnected or short-
circuited. To ensure safety, we recommend that you connect the
external circuits so that you can use a negative voltage input for the
overheat protection input (an analog voltage input).
