Overheat Protection Selection
The overheat protection function is selected with Pn61A = n.
X (Overheat Protection
Selections).
*
The SGLFW2 is the only Yaskawa Linear Servomotor that supports this function.
Using Overheat Protection in the Yaskawa Linear Servomotor
To use the overheat protection in the Yaskawa Linear Servomotor (SGLFW2), set Pn61A to
n.
1.
An A.93B warning (Overheat Warning) will be detected if the overheat protection input (TH) sig-
nal from the Yaskawa SGLFW2 Linear Servomotor exceeds the warning temperature.
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.
Monitoring the Machine’s Temperature and Using Overheat
Protection
Set Pn61A = n.
X to 2 or 3 to use overheat protection for the machine.

If the overheat protection input signal line is disconnected or short-circuited, an A.862 alarm
will occur.

When Pn61A is set to n.
3, an A862 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).
