EX3 – EX4 – EX6 – EX8
You detect
vibration:
If the thermal
probes are
activated:
You find the motor Various possible reasons:
too noisy:
Conserver cette notice d'instruction
Check on the servomotor phase order: U, V, W
–
– Check on the resolver connections, the ground connections, the
earthing, the setting for the servoamplifier speed loop, and the
shielding.
Check on the stability of the auxiliary voltages.
–
– It could be overloaded: check on the current and the servomotor
operating cycle.
– There could be too much machine friction:
•
Test the motor load and no-load currents.
•
Check that the motor is not thermally insulated.
•
Check that there is no friction from the brake when the brake
power is on.
•
Poor mechanical balancing
•
There is friction from the brake: mechanical jamming.
•
Faulty coupling
•
Different parts require tightening
•
Unsuitable servoamplifier or position loop settings: check on
the rotation with the loop open.
