Sensor Module Cabinet-Mounted SMC30
7.2 Interface description
Pin
Connector type: 15-pin Sub-D socket
Measuring current via temperature sensor connection: 2 mA
1) Accuracy of temperature measurement:
- KTY: ±7°C (including evaluation)
- PTC: ±5℃ (including evaluation)
NOTICE
Damage to the encoder due to incorrect supply voltage
The encoder supply can be parameterized to 5 V or 24 V. The sensor may be destroyed if you
enter the wrong parameters.
● Select the appropriate supply voltage.
NOTICE
Damage to motor in the event of incorrectly connected KTY temperature sensor
A KTY temperature sensor connected with incorrect polarity cannot detect if the motor
overheats. Overheating can cause damage to the motor.
● Connect a KTY temperature sensor with the correct polarity.
Details on the parameterization of the KTY temperature sensor can be found in the Function
Manual.
Electric shock in the event of voltage flashovers at the temperature sensor
Voltage flashovers in the signal electronics can occur in motors without safe electrical
separation of the temperature sensors.
● Use temperature sensors that comply with the specifications relating to protective
● If safe electrical separation cannot be guaranteed (e.g. for linear motors or third-party
