Commissioning

9.1 Safety guidelines for commissioning

WARNING

The surface temperature of the motors may be more than 100 °C (212 °F). Risk of burns

Make sure that the cooling system (if available) is working properly. Do not touch the motor during/directly after use.

Display the "Hot Surface Do Not Touch" (D-W026) warning sign clearly in the vicinity of the motor.

Temperature-sensitive parts (electric cables, electronic components) may not be placed on hot surfaces.

CAUTION

The motor may overheat without temperature protection and be destroyed.

Before(!) switching on for the first time (for testing), check whether the temperature protection is effective!

WARNING

During torque motor operation, the rotor must not exceed a temperature of 120°C otherwise the permanent magnet may become demagnetized.

This must be ensured during initial commissioning by carrying out the appropriate checks.

Special attention should be paid here to non-uniform current loads during standstill or operation with short, cyclic rotation because this can generate extremely high, localized temperatures.

DANGER

Risk of death, serious personal injury and/or material damage if the safety guidelines and instructions are not observed.

Note the safety information provided in this documentation.

For 1FW6 torque motors, the commutation setting required for synchronous motors can be made via the software-based automatic rotor position identification procedure.
