X520 encoder connection 1 for HTL/TTL/SSI encoder with open-circuit monitoring
Table 9- 28
Connector
Connector type: 15-pin Sub-D socket
Measuring current via temperature sensor connection: 2 mA
Accuracy of the temperature measurement:
1)
- KTY: ±7 °C (including evaluation)
- PT1000: ±5 °C (PT1000 tolerance class B according to EN 60751 including evaluation)
- PTC: ±5 °C (including evaluation)
NOTICE
Damage to the motor in the event of incorrectly connected KTY temperature sensor
If a KTY temperature sensor is connected with incorrect polarity, it is not possible to detect
when the motor overheats. Overheating can cause damage to the motor.
• Connect a KTY temperature sensor with the correct polarity.
NOTICE
Damage to the encoder due to incorrect supply voltage
The encoder power supply can be parameterized to 5 V or 24 V. The encoder may be
damaged if you enter the wrong parameter.
• Select the appropriate supply voltage.
