WARNING: The use of extra-quick fuses FU1/2 is recommended to protect the internal
power module in case of undesired external short-circuits. Comply with the max.
prescribed value for I2t.
The L1 switching impedance is 35A/150µH
(ELETTRONICA SANTERNO code: IM0100354).
The current FF form factor can be obtained by measuring the effective value
[ ] ae

EMI CHARACTERISTICS AND INPUT FILTEREMI CHARACTERISTICS AND INPUT FILTER
Radio-frequency interferences (RFI) can be generated in the area where the drive is installed. The
interferences can occur both on the air (irradiated interferences), and through the power and signal cables
(conducted interferences). Sometimes, due to these interferences, the drive can operate improperly, even
if the AMS90/1 unit is provided with a high noise immunity and complies with the EMI standards. Also, the
drive itself can produce interferences due to switching over of power semi-conductors representing its
output stage.
A malfunction can be detected in the devices installed close to the drive or connected at the same supply
or earth conductor.
To eliminate any interference that can affect the drive operation, proceed as follows:
-keep the drive power cables separated from the signal cables;
-use shielded cables for drive control signals and connect the shield to ground, as shown on the
connection diagram; for shield grounding, choose the shortest connection, that should be direct and
without any intermediate connection;
-always install anti-noise filters on the coils of remote control switches, solenoid valves, etc.
IMMUNITY TESTS OF AMS90/1
Electrostatic discharges: level 3 EN 61000 - 4 – 2
Burst: level 3 EN 61000 - 4 – 4
Surge: level 3 EN 61000 - 4 – 5
Radio-frequency electromagnetic fields: 10V/m IEC 1000 - 4 - 3
If malfunctions are detected in the devices installed close to the drive, take the following precautions:
- install the drive input filter;
-keep the drive power cables separated from any other cable;
-use shielded cables to connect sensors, instruments, etc.
-install any noise-sensitive devices as far as possible away from the drive.
WARNING! THE CONNECTION CABLES BETWEEN FILTER AND DRIVE SHOULD BE AS
SHORT AS POSSIBLE.
Here is a list of the filters recommended for the different drive models, so that the conducted and irradiated
interferences are included within the levels conforming to EN55011 class B and VDE0875G (civil
environment) standards. On the contrary, these filters are not required for industrial environments,
where the switching inductance is enough.

INSTALLATION, CALIBRATION AND MAINTENANCEINSTALLATION, CALIBRATION AND MAINTENANCE
PRELIMINARY CONTROLSPRELIMINARY CONTROLS
After receiving the drive, check it carefully in order to verify the presence of damages
due to transport. If so, take the necessary measures. Check that all the rating
corresponds to the application, as shown on the cover label.
If not, contact your dealer or ELETTRONICA SANTERNO.
INSTALLATIONINSTALLATION
The drive must be positioned so as to allow for air circulation in vertical direction. See
fig. 1: External and fixing dimensions.
When connecting the unit, comply with the following precautions:
1. Avoid positioning the wires of the tacho generator and of signals closes to the power
cables and other possible electromagnetic trouble sources. If more accuracy is
required in the control system, use shielded cables externally insulated for speed
reference and tacho generator feedback. The shield must be connected in the
shorter and more direct way to the ground, without any intermediate connection.
2. Make connections as short as possible.
3. After wiring, check if connections and solderings are correct and check the proper
positioning of jumpers and dip-switches, as regards the supply voltage and
frequency and the drive application.
4. Supply the control section at terminals 25 and 26 and check that LEDs (L1) 15V and
(L2) n=0 are on.
5. After supplying the field rectifier circuit at terminals 27 and 28, check the presence
of the direct voltage required for D.C. motor field supply at terminals 29 and 30.
6. Close the KM remote control switch and the KA contact (if any) connected in series
to the NO auxiliary contact of the remote control switch, and check that LED (L3)
RUN is turned on.
7. Send the speed reference to term. 7 (or 4) and check the motor is started. If this
does not happen and the LED (L4) LIM turns on, check if this condition is caused by
one of the following reasons:
a) The supply of term. 25-26 IS NOT IN PHASE with that of term. 23-24 (with closed remote control
switch, a zero alternate voltage should be present between term. 23 and 25, and term. 24 and 26).
b) An interruption occurred in one of the extra-quick fuses FU1-2 or in the armature connection.
c) Trimmer RV7 (I LIM) is fully rotated in counter-clockwise position (current limit is zero).
d) The drive is preset for external current limit (J5 ⇒E) and no negative voltage is applied to term. 9.

... cont. INSTALLATION, CALIBRATION AND MAINTENANCEINSTALLATION, CALIBRATION AND MAINTENANCE
CALIBRATION
The drive is usually delivered with preset calibrations, according to the data received
when ordering the unit, or based on the STANDARD CONFIGURATION.
If calibration data have to be checked or changed, proceed as follows:
a) Reduction of current limit below rating value:
1. Disconnect one of the two cables powering term. 27-28 and insulate it.
2. Connect an instrument for motor armature D.C. measurement.
3. Send a speed reference with intermediate value, close the line remote control switch
and the RUN contact.
4. Check the armature current value through the previously connected instrument, and,
if required, adjust the current value by rotating trimmer (RV7) I LIM. The value
shown by the instrument must reach the required continuous value.
5. If an ammeter is connected to terminal 12, check for data consistency, always
remembering that the unit sends a +10VDC signal at rated current (10, 20 or 30A,
depending on the circumstances).
IMPORTANT: The last two operations should be performed in the shortest time. Finally, reset the
supply of the field rectifier circuit (term. 27-28).
b) Maximum speed calibration
1. Start the machine by pressing the start push-button.
2. Rotate the speed potentiometer to the max. value.
3. Turn trimmer (RV9) n MAX so that the machine speed is at max. value, and check
that motor rating data, that is max. speed and max. armature voltage, is not
exceeded.
c) Speed ramp adjustment
1. Rotate the potentiometer to the max. value.
2. Start the drive.
3. If the time required by the drive to reach the maximum speed (voltage) is too short
or too long, rotate trimmer (RV4) UP. Otherwise, use trimmer (RV5) DOWN to
adjust the slope. Note: the drive can control the slope only if the set ramp is longer
than the normal inertia slope (i.e. the one obtained through idle stop). Further, it can
control the rise, provided that it does not enter the current limit condition, i.e.
provided that the rise ramp is not too short.

d) Stability calibration
Connect the speed potentiometer to the direct input at term. 4 and suddenly increase
the reference. Then, adjust trimmer (RV3) STAB so that the new speed value is
reached without excessive overshoot with a long settling time, and without too quick
and unstable dampings. In the first case, rotate the trimmer in CW direction, otherwise
rotate it CCW.
e) Calibration of RxI compensation (without tacho generator only).
Adjust trimmer (RV8) COMP to minimize the speed loss that occurs in motor when the
load requires an increase of torque and absorbed current.
Note: an excessive adjustment may cause instability.
f) Speed offset calibration
If, with potentiometer at zero speed, the motor rotates slowly (unless a min. reference
has been applied to the potentiometer negative end), carefully rotate trimmer (RV10) n
OFS in CCW direction and stop the motor.
Note: an excessive adjustment may introduce an initial not-sensitive area in the speed
reference adjustment scale.
MAINTENANCEMAINTENANCE
The drive maintenance is mainly a matter of periodical checking.
The first precautions against troubles due to malfunction, are the cleanliness of the
machine and its installation in an environment free of vibrations and not too hot. All this
will allow for a long life of all components.
A prompt attention to any trouble, even the smallest ones, detected during periodical
inspections, will certainly help for drive longlife and avoid expensive operation breaks.
