YASKAWA Sigma-7 SGD7S Series

7.15 Overheat Protection
7.15.1 Overview
Overheat protection detects an A.93B warning (Overheat Warning) and an A.862 alarm
(Overheat 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).
7.15.2 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 pro-
tection input (TH) signal.
n If you use a Serial Converter Unit, connect the connector for the polarity sensor and
thermostat cable of the Linear Servomotor to the Serial Converter Unit.
n If you do not use a Serial Converter Unit, connect the thermostat cable of the Linear
Servomotor to CN1-5.
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.
7.15.3 Overheat Protection Selections
The overheat protection function is selected with Pn61A = n.X (Overheat Protection
Selections).
Parameter Meaning When Enabled Classification
Pn61A
n.0
(default
setting)
Disable overheat protec-
tion.
After restart Setup
n.1
Use overheat protection
in the YASKAWA Linear
Servomotor.*
n.2
Monitor a negative
voltage input from a
sensor attached to the
machine and use over-
heat protection.
n.3
Monitor a positive
voltage input from a
sensor attached to the
machine and use over-
heat protection.
* The SGLFW2 is the only YASKAWA Linear Servomotor that supports this function.
