When the actuator is operated for the first time, there is a risk of unintended equipment operation caused by possible wiring errors or unsuitable parameters.

|
|
UNINTENDED EQUIPMENT OPERATION |
|
oVerify that the actuator is properly fastened so it cannot come loose even in the case of fast acceleration. oTake all necessary measures to ensure that the moving parts of the actuator cannot move in an unanticipated way. oVerify that emergency stop equipment is operational and within reach of the zone of operation. oVerify that the system is free and ready for the movement before starting the system. oRun initial tests at reduced velocity. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
If the motor power supply is disabled unintentionally, for example as a result of power outage, errors or functions, the motor is no longer decelerated in a controlled way.
|
|
|
UNINTENDED EQUIPMENT OPERATION |
|
Verify that movements without braking effect cannot cause injuries or equipment damage. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
The motor, the belt drive, and the adaptation materials of the actuator may exceed 70 °C (158 °F) when subjected to heavy loads and/or high performance during operation.
|
|
|
HOT SURFACES |
|
oAvoid unprotected contact with hot surfaces. oDo not allow flammable or heat-sensitive parts in the immediate vicinity of hot surfaces. oVerify that the heat dissipation is sufficient by performing a test run under maximum load conditions. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
For further information, refer to Hot Surfaces.
NOTE: Perform a start-up in case of an already configured actuator when it is used under modified operating conditions. For more information, refer to Specific Safety Information.

Step |
Action |
|---|---|
|
1 |
Verify the installation. For more information, refer to Verifying the Installation. |
|
2 |
Comply with the instructions provided in the manual of the motor used and in the manual of the drives used. |
|
3 |
Verify that the loads conform to the appropriate specified forces and torques for the actuator and the machine it contains before operating the actuator. |
|
4 |
Limit the maximum torque of the motor in accordance with the maximum drive torque of the actuator. |
|
5 |
Verify the function of the sensors. |
|
6 |
Verify the distance between the sensors and the mechanical stops. The movement must be stopped by the sensors before reaching a mechanical stop. |
|
7 |
Perform initial tests at reduced velocity. During these tests, verify that the controller responds without any error or warning message to the signals of the sensors in both directions of movement. NOTE: Consider that the forward movement is stopped on a trigger signal of the forward overtravelling sensor and as does a backward movement. |
|
8 |
Verify that the ambient conditions conform to the appropriate specified environments for the actuator and the machine it contains. For details, refer to Ambient Conditions. |
NOTE: The maximum permissible dynamic forces and torques decrease with increasing velocities and depend on the mechanical fastening of the actuator. For more information, refer to the respective characteristic curves in catalog Unimotion PNCE Electric Cylinder .
