Destruction of the AX5000!

Read the "Cables" chapter carefully and be sure to adhere to the specifications contained in it.

Temperature monitoring for Beckhoff motors

AM2000 with resolver
Via resolver cable.

AM2000 with EnDat
The thermal protection contact is implemented in the encoder cable to the AX5000 and must be bridged to the resolver connection via an adapter / Y cable.

AM2000 with BiSS
Not available.

AM3000 with resolver
Via resolver cable.

AM3000 with EnDat
Via motor cable.

AM3000 with BiSS
Via motor cable.

Linear motors AL2000
The thermal protection contact exits the motor via a separate cable.

  1. If pre-assembled Beckhoff motor and encoder cables are used, then the ZK4540-0020-xxx thermal protection contact cable is also required. This connects the thermal protection contact with the resolver interface of the AX5000, on which only the temperature evaluation then takes place.
  2. If the AL2250 connector box is used, the thermal protection contact is automatically bridged to the motor cable.

Temperature monitoring and evaluation for motors from other vendors

1. Temperature monitoring by means of PTC, Klixon or bimetal
Evaluation either on resolver interface X12 / X22 or on temperature contact X14 / X24

2. Analog temperature evaluation (e.g. KTY)
Evaluation only on temperature contact X14 / X24
