6.14 Overheat Protection
6.14.2 Overheat Protection Selection
Using Overheat Protection in the Yaskawa Linear Servomotor
To use the overheat protection in the Yaskawa Linear Servomotor (SGLFW2), set Pn61A to

n.
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.
Important
Monitoring the Machine's Temperature and Using Overheat
Protection
Set Pn61A = n.X to 2 or 3 to use overheat protection for the machine.
Set the following parameters as required.

• 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
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)
