OPERATIVE
MODE
By setting the bit on the J2 connector you can select one of the following operatives mode:
MODE 0 - RESET/ EMERGENCY [Li.1, Li.2, Li.3 = Off]
RESET duration ≥ 300ms
Setting Off all bits the drive is disabled, in this condition
the engine and outputs st. index, st. lock and position feedback are reset.
This mode is necessary to reset an alarm.
After a reset to recall a position you must repeat the
zero search or hidden zero search.
MODE 1- AUTOMATIC POSITIONING IN THE SHORTEST WAY AND ZERO SEARCH [Li.1=On Li.2,Li.3 = Off]
Use this modality by default.
When the mode 1 is selected the turret will reach the required position by choosing the shortest way.
The mode 1 is necessary also to perform a zero search or hidden zero search.
It is recommended to set this mode already at switch on otherwise an alarm is not displayed.
MODE 2 - AUTOMATIC POSITIONING WITH FORCED CLOCKWISE ROTATION [Li.2=On Li.1,Li.3 = Off]
MODE 3 - AUTOMATIC POSITIONING WITH FORCED COUNTERCLOCKWISE ROTATION[Li.1,Li.2=On Li.3 = Off]
The turret will reach the required position respecting the direction of rotation chosen
even though this means a greater distance.
MODE4 - NEXT/PREVIOUS TOOL REQUEST (JOG MODE) [Li.3=On Li.1,Li.2 = Off]
With this modality the user is able to change the turret position without a program. This function is useful for
manual operations (pre-setting, tool replacement).
For each START command the turret will perform a jump of 1 station in the direction of rotation set:
Mod.4 + 1 position clockwise rotation
Mod.4 + 2 position counter-clockwise rotation
MODE 5 - SERVICE MODE
[Li.1,Li.3=On Li.2 = Off]
Use this function for understand if the electrovalve system it's ok or evaluate the turret noise.
These operations are only possible if st index, st lock and feedback are disabled.
For each START command the turret will do one of the following:
Mod.5 + Position 1 - fast continuous rotation clockwise
Mod.5 + Position 2 - fast continuous rotation counter-clockwise
Mod.5 + Position 5 - slow continuous rotation clockwise
Mod.5 + Position 6 - slow continuous rotation counter-clockwise
Mod.5 + Position 4 - EV locking turret
Mod.5 + Position 8 - EV unlocking turret
Set RESET (mod.bit = 0) to stop continuous rotation.
The parity bit should be managed according to the required position.
MODE 6
–
AUTOTEST [Li.2,Li.3=On Li.1 = Off]
Use the autotest to skip the plc program and check if the turret works correctly.
Set the mode to 6, give the START command , wait 5" after
the turret will search for zero and at intervals of 5" recall
some positions.
Set RESET (mod.bit = 0) to break the cycle.
MODE7 - RESOLVER ACQUISITION [Li.1,Li.2,Li.3=On]
This is an alternative procedure to the one made with dipswitch pin n°10, with the difference of the unlocking
turret.
Set the turret locked in the position 1.
Set mode 7
Give the 1st START - EV unlocking command will be executed
Give the 2nd START - EV locking command will be executed.
The operative mode n°2-3-
4 are enabled only after a
positioning in the operating
mode 1
