1. Start
check travel
with low dynamic response.
In spite of equal control, motors of the same design sometimes turn in the opposite direction due to
different wiring.
2. Start
homing
in accordance with the operating instructions for your motor drive system with low
dynamic response to the reference switch.
The homing run may only take place toward the reference switch.
3. Start a
test run
with low dynamic response.
4. Check whether the EGC fulfils the following conditions:
–
The slide runs through the complete intended positioning cycle.
–
The slide stops as soon as it reaches a limit switch.

Operation
Warning
Moving masses can cause personal injury or damage to material items (crushing).
Make sure that, in the positioning range
–
nobody can place his/her hand in the path of the moving components
(e.g. through protective guards)
–
there are no foreign objects.
It should not be possible to grasp the EGC until the mass has come to complete rest.
Note
The reference position is lost when the motor is dis
mounted (e.g. turning of the motor).
Start homing (
