Electrical Installation - Hazards
The following hazards exist during installation. Please proceed carefully and
professionally.
NOTICE
Protect the servomotor from overheating!
Without monitoring the temperature in the motor by means of suitable
sensors, the motor can become too hot.
Integrate the thermistor of the motor into the monitoring
system of the servo amplifiers.
Never operate the motor without integrating and evaluating the
built-in temperature sensor KTY83-110 (PTC). To do this, route
the temperature sensor signal in the encoder connector of the
motor to the respective input of the servo amplifier. For older
motors, appropriate thermal sensors must be used.
If the temperature monitor detects that the resistance of the
temperature sensor is greater than 2150 Ohm, the servo
amplifier must switch the motor off and issue the message
"Motor temperature error".
The JM-2xx, JM-35xx and JM-1yxx servo amplifiers support motor
temperature monitoring and switching off in the event of
overheating.
Our motors comply with insulation class F. Thus, the insulating
materials of the motor are designed for a maximum temperature
of 155 °C.
According to the ATEX directive, the temperature must therefore
not exceed 155 °C.
