1SAFETY AND INSTALLATION
1.1 SAFETY CONSIDERATION AND INSTALLATION CONSTRAINS
It is important to ensure that cable and connection are carried out by a qualified technician. Wrong
connections can cause damage to the device or generate dangerous situations for the user.
Dangerous voltages can be found inside the drive and on the external clamps, therefore
maximum attention should be paid during all phases of installation and/or maintenance so
that people are not placed in dangerous situations.
►After switching off the drive, the internal components and the output connectors can still be powered for
several seconds. Before doing anything, check with a Voltmeter that there are no dangerous voltages
on the external clamps.
►Between the control signals and the main power supply the insulation is guaranteed only for functional
purposes and not for user safety.
►All the logic signals, besides the power lines, must be protected against the user direct contact.
►During installation or normal operation, do not use damaged cables or spoiled ones.
►Connect to the ground all the shields and the ground cables. Avoid untidy or twisted cables.
►The converter must be installed in vertical position into the cabinet. Ventilation conditions and surrounding
atmosphere must be settled in a way that the converter cannot work without nominal temperature
range (0÷40°C).
►Relative air humidity must be kept below 90%, with no condensation
►A 150mm clearance area must be considered over and under the driver, the drives and 50mm on the sides
in order to guarantee a high cooling efficiency to the fan.
►The converter heat sink can reach high temperature during normal operations. Avoid direct contacts and
remove inflammable components into the closeness of the converter.
►Before proceeding with the setup of the device it is necessary to check the ground connections, network
voltage and the correct connection (according to this manual) of the control signal connections
1.2 EMC ADVICES
All the cables connected to the Drive must be shielded and grounded.
►An insulation transformer on the power line decoupling the drives from the grid is always a high efficiency
EMC barrier.
►Where it is necessary to intersect the lay out between signal cables and power cables, it is better that the
intersections are made with cross angles of 90.
►With cables length over 8/10m is not guarantee a full protection from EMC.
In case of this over length it is necessary to adapt all the measure to guarantee the complete elimination of EMC
and interference in the machine cables, e.g.:
- It is necessary separate the turret cables from other machines cables, using per example separate canalisations
(with a distance of at least 30cm one from the other cable).
- The using of an external shielded wiring harness on the turret cables.
- External line filters are recommended (ie: Arctoronics F.LL.D3.016A.BN.R1 for 10A)

►It is advisable to install the power parts of the motor control unit (drive, transformer, filters and resistances)
in metallic divisions separate from those assigned to command and control devices. If the power supplies of
the power groups are the same as the control apparatus, they should be connected in the same position
(entrance point of the electronic device) in a star configuration.
WITH OTHER DRIVE
The servo amplifiers must not be install
in the venting flow of other devices
ALL SHIELDED CABLES
All the cables must be shielded and
connected to the ground in order to
prevent EMC problems
TURRET CABLE INSTALLATION
It is necessary to separate the turret cables from
other machines cables (e.g separate
canalisations) or the use of an external shielded
wiring harness on the turret cables
TEMPERATURE RANGE
Smooth operations and life of Servo amplifier
module rely on keeping temperature at all
times within the operating range of 0°C to
+40°C. Temperature should then regularly
be checked
150mm
DRIVE CLEARANCE
The Drive must has a clearance of
50mm on the side and 150mm
over/under the drive
VERTICAL POSITION
Servo amplifier module must be installed in vertical
position only. Sideways or horizontal placement should
not be made, as in this way correct heat exhaustion
isnot guaranteed, and failures would occur

5. J1 INPUT/OUTPUT
5.1 CONSENT TO WORK
It is possible to start to work only when both signals are active:
- ST INDEX (J1pin.8) = turret in position
- ST LOCK (J1pin.17) = turret closed
In addition to these two signals is possible using the binary outputs of the POSITION FEEDBACK to make sure
that the turret is in the position required.
Outputs are reset:
- in case of alarm
- during rotation of the turret
- drive reset (mode = 0)
5.2 POSITION FEEDBACK
n° 5 binary outputs communicate the position of the turret. The position can be seen on display in the front of
the drive.
The outputs are only active with turret indexed ie has already been done a positioning or zero search (even
hidden).
The outputs are active when:
- the turret is closed in the position
- no alarms are present
- the drive is not in reset mode (mode bit off)
The position feedback is in binary code (see table at left) without the parity bit
5.3 ALARMS
N°5 binary outputs communicate the presence of an active alarm. In order to facilitate the
diagnosis, the active alarm is displayed on the front display.
The activation determines:
- rotation stop
- deactivation of outputs St index, St lock and position feedback.
To perform a new positioning is necessary to reset the alarm by setting the operating mode zero.
5.4 START COMMAND
Should be: min 100ms /Max 200ms
It 'important that the command is given with a delay of at least 50ms after the setting of the required position.

6. DIPSWITCH SETTING (FOR TURRET TYPE SELECTION)
TURRET SELECTION
The setting of the turret type, the number of positions and dynamic profile must be performed before
starting the drive (24Vdc).
CUSTOM PROFILE
For nonstandard applications can be set via software a specific profile setting manually the
transmission
ratio (T.R.), number of stations and dynamic profile, in this case a red label will be applies on the
drive.
In order to replace the drive will be necessary reset the profile via p.c. on the new one.
The custom profile is added to the standard profiles.

DYNAMIC PROFILE
It is possible to optimize the dynamic response of the drive according to the real load condition and
unbalance applied to the turret.
The dynamic profile acts on the values of rounding ramp, target speed, acceleration, deceleration and
compensation of inertia.
RESOLVER ACQUISITION
With this operation will be stored in the drive the value of the resolver when the turret is in position 1,
this value will be used to verify that the required station is reached by the turret at the end zero
research (also hidden zero research).
This procedure is performed in the factory during the test drive turret and need to be repeated only in
the case that the drive or the motor are substituted or when the motor is removed from the turret.
Sequence:
-Make sure the turret is closed in position 1
-Switch on the drive
- Set to ON the dipswitch n°10
- At the end of 5" counting re-set the pin n°10 OFF
- The "SA" letters on the display means that the acquisition is finished
- The Drive is now ready to work
FAST PROFILE
Preferable when the inertia
is low. It allows to obtain
positioning times lower.
MEDIUM PROFILE
Similar to the universal but
with lower ramp rounding.
LOW PROFILE
Limited speed
Can be used during machine the setup.
UNIVERSAL PROFILE
Very soft acceleration
and deceleration
ramps. Ideal for any
type of inertia.

- Resolver failure 8.0 at startup
- Locking Error (5.x) after position inquiry
- Position Error (6.x) after position inquiry
ZERO SEARCH*
Zero search (also hidden) has to be performed
after switch on the drive or a reset.
ZERO SEARCH
-Operative mode 1
-Position required = 0
-Wait ≥50ms
- START (≥100ms)
The turret will rotate in the CW direction at
low speed and will stop in the mechanical
station 1.
HIDDEN ZERO SEARCH
-Operative mode 1
-Position required ≥ 2
-Wait ≥50ms
-START (≥100ms <500ms)
The turret will rotate in the CW direction at
low speed, pass over through the mechanical
station 1 without stops and goes straight to the
position required.

8. 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
