Note
The maximum cable length to encoder systems is 100 m. The specified supply voltage of the
encoder must be observed.
Note
Pins 1/9 and 2/11 on the SMC40 side and on the encoder side (in the M12 connector, pin 8/2 and
pin 5/1) are connected in parallel, and to increase the cable cross-section each must be wired
with a separate conductor.
Electric shock when the motor temperature sensor insulation fails
When connecting temperature sensors which are not isolated from the motor power circuit
according to safe electrical separation, arcing to the signal electronics may occur.
• Use motors whose temperature sensors have safe electrical separation.
• Use only connecting cables and connectors with safe electrical separation between the
• If safe electrical separation cannot be guaranteed (for linear motors or third-party motors,
