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.
• 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 Yaskawa Linear Servomotor), the
Important
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)
Monitoring the Machine's Temperature and Using Overheat
Protection
Set Pn61A = n.X to 2 or 3 to use overheat protection for the machine.

external circuits so that you can use a negative voltage input for the overheat protection input (an
analog voltage input).
