5. Operation
5-1 Cautions on operation
5-2 Repeated operation in small travel
The grease of the ball screw may become low only with back-and-forth movement of 2mm or less.
Low grease may cause abnormal wear or galling, causing deterioration of positioning accuracy or shorter life.
Perform operation of 4mm or more a few times every 1000 operations to spread grease on the ball screw.
For details, consult with your distributor or one of our sales offices.
Do not insert your hand in the output rod (movement shaft) of
the linear actuator.
Do not touch the terminal for 3 minutes after power off.
CAUTION
◆
Perform operation of 4mm or more sometimes to improve
the lubrication of the ball screw. Otherwise it may cause
deterioration of positioning accuracy or shorter life.
CAUTION
◆
Operation cannot be done by power on/off. It deteriorates
the internal circuit elements.
◆
Perform operation/stop of the actuator by using command
signals.
◆
Do not use control method by hit and stop of the output
rod. It may cause failure or poor performance.
◆
Do not touch the moving parts including the output rod
during operation.
It may cause injury due to getting caught or pinched.
◆
Do not perform connection operation during excitation.
Turn off the power before starting operation. It may cause
an electric shock or burning.
◆
Operate it not to exceed the maximum feed speed. It may
cause failure or poor performance.
◆
If any error occurs, immediately perform emergency stop.
It may cause an electric shock or injury.
◆
If the linear actuator runs away with the load applied and
the mechanical limit travel is exceeded, it may cause
failure or injury. Electric recovery may become difficult.
◆
Load cannot be held upon alarm stop due to runaway or
driver power off. The output rod may move in the
reversed direction due to the load.
