Overheat Protection

Overheat protection detects an A.93B warning (Overheat Warning) and an A.862 alarm (Over-
heat Alarm) by monitoring the overheat protection input signal (TH) from a Yaskawa SGLFW2
Linear Servomotor or from a sensor attached to the machine.
SERVOPACKs with software version 0023 or higher support overheat protection.
When you use overheat protection, you must wire the overheat protection input (TH) signal and
select overheat protection (Pn61A = n.X).

Connecting the Overheat Protection Input (TH) Signal

To use overheat protection, you must connect an overheat protection input (TH) signal to the
SERVOPACK. This section describes the connection methods for the overheat protection input
(TH) signal.
Using Overheat Protection in the Linear Servomotor
• If you use a Serial Converter Unit, connect the connector for the polarity sensor and thermo-
stat cable of the Linear Servomotor to the Serial Converter Unit.
• If you do not use a Serial Converter Unit, connect the thermostat cable of the Linear Servo-
motor to CN1-5.
Using Overheat Protection for the Machine
To use overheat protection for the machine, connect the overheat protection input (an analog
voltage input) from the sensor mounted to the machine to the CN1-5.
