Permissible rotation
speed
Encoder-mounted shaft speed (6000r/min)
The motor and encoder-mounted shaft must be coupled directly or via a belt without any slip. A
gear change type cannot be used.
Functions
•
Orientation and creep speed setting.
•
Stop position command selection.
•
DC injection brake start position setting.
•
Creep speed and position loop select position setting.
•
Position shift.
•
In-position zone.
•
Position signal monitoring, etc.
Note: Set the above functions from the parameter unit.
Holding force after
positioning
Without servo lock function (However, the servo lock function is valid when "2" is set in Pr. 370
to choose vector control.)
Input signals
(contact input)
•
Orientation command.
•
Forward and reverse rotation commands.
•
Stop position command (open collector signal may also be entered). Maximum 12-bit binary
signal.
Output signals (open
collector output)
•
In-position signal.
•
Orientation fault signal.
DC power supply
Prepare a 5VDC power supply for the encoder.
(Usually approximately 350mA)
5V, 50mA is also required for the option.
Supply power from the NC or use a general power supply.
Example:DENSEI-LAMBDA EWS15-5 (5V, 3A)
*When encoder feedback control and orientation control are used together, the 5V power
supply is shared between these controls.
