WARNING!
– Carefully read the manual before the installation or use.
– This equipment is to be installed by qualified personnel, complying to current standards, to avoid
damages or safety hazards.
– Before any maintenance operation on the device, remove all the voltages from measuring and supply inpu
and short-circuit the CT input terminals.
– The manufacturer cannot be held responsible for electrical safety in case of improper use of the equipment.
– Products illustrated herein are subject to alteration and changes without prior notice. Technical data and
descriptions in the documentation are accurate, to the best of our knowledge, but no liabilities for errors,
omissions or contingencies arising there from are accepted.
– A circuit breaker must be included in the electrical installation of the building. It must be installed close by
the equipment and within easy reach of the operator. It must be marked as the disconnecting device of the
equipment: IEC /EN/BS 61010-1 § 6.11.3.1.
– Clean the device with a soft dry cloth; do not use abrasives, liquid detergents or solvents.
ATTENTION !
– Lire attentivement le manuel avant toute utilisation et installation.
– Ces appareils doivent être installés par un personnel qualifié, conformément aux normes en vigueur
en matière d’installations, afin d’éviter de causer des dommages à des personnes ou choses.
– Avant toute intervention sur l’instrument, mettre les entrées de mesure et d’alimentation hors tension et
court-circuiter les transformateurs de courant.
– Le constructeur n’assume aucune responsabilité quant à la sécurité électrique en cas d’utilisation impropre
du dispositif.
– Les produits décrits dans ce document sont susceptibles d’évoluer ou de subir des modifications à n’importe
quel moment. Les descriptions et caractéristiques techniques du catalogue ne peuvent donc avoir aucune
valeur contractuelle.
– Un interrupteur ou disjoncteur doit être inclus dans l’installation électrique du bâtiment. Celui-ci doit se
trouver tout près de l’appareil et l’opérateur doit pouvoir y accéder facilement. Il doit être marqué comme le
dispositif d’interruption de l’appareil : IEC/ EN/BS 61010-1 § 6.11.3.1.
– Nettoyer l’appareil avec un chiffon doux, ne pas utiliser de produits abrasifs, détergents liquides ou solvants.
ACHTUNG!

ATTENZIONE!
– Leggere attentamente il manuale prima dell’utilizzo e l’installazione.
– Questi apparecchi devono essere installati da personale qualificato, nel rispetto delle vigenti
normative impiantistiche, allo scopo di evitare danni a persone o cose.
– Prima di qualsiasi intervento sullo strumento, togliere tensione dagli ingressi di misura e di alimentazione e
cortocircuitare i trasformatori di corrente.
– Il costruttore non si assume responsabilità in merito alla sicurezza elettrica in caso di utilizzo improprio del
dispositivo.
– I prodotti descritti in questo documento sono suscettibili in qualsiasi momento di evoluzioni o di modifiche.
Le descrizioni ed i dati a catalogo non possono pertanto avere alcun valore contrattuale.
– Un interruttore o disgiuntore va compreso nell’impianto elettrico dell’edificio. Esso deve trovarsi in stretta
vicinanza dell’apparecchio ed essere facilmente raggiungibile da parte dell’operatore. Deve essere marchiato
come il dispositivo di interruzione dell’apparecchio: IEC/EN/BS 61010-1 § 6.11.3.1.

TYPE ITEM FUNCTION
Digital display and LEDs Main views Frequency, parameters, voltage, current, temperature, fault messages.
LED Status – Hz/RPM: ON when the frequency or line speed is displayed. OFF when the parameters are displayed.
– FWD: ON while the drive is running forward. Flashes while stopped.
– REV: ON while the drive is running reverse. Flashes while stopped.
– FUN: ON when the parameters are displayed. OFF when the measures are displayed.
Potentiometer FREQUENCY Used to set the frequency
Keys on keypad RUN RUN: run at the set frequency.
STOP/RESET
(dual function)
- STOP: Decelerate or coast to stop.
- RESET: Use to reset alarms or resettable faults.
Increment parameter number and preset values.

1.3 MODIFYING PARAMETERS
1.4 STATUS LEDS DESCRIPTION
To reset the drive parameters to the factory settings set the parameter 13-08 to one of the following values according to the system rated voltage and frequency (typical value: 1250).
1150: initialization (50Hz,220V/380V)
1160: initialization (60Hz,220V/380V)
1250: initialization (50Hz,230V/400V)
1260: initialization (60Hz,230V/460V)
1350: initialization (50Hz,220V/415V)
1360: initialization (60Hz,230V/400V)
To modify the parameters, use the following keys of the frontal keypad:
• MODE: it allows to switch from the measures view to the parameter view
• : with a quick pressing it is incremented or decremented the selected digit by one (parameter index or value). With an extended pressing it is incremented or
decremented the selected digit continuously
• </ENT : a quick pressing allows to move between the digits of the selected parameter or to access to the parameter to see its value. With an extended pressing it is saved the
value of the modified parameter.

5 MOTOR PARAMETERS
All the other parameters must be left to default settings.
In case of setting 00-00=0, the V/f characteristics shape can be set with parameter 01-00.
SLV (Sensorless vector) control is used for obtaining best performance from a motor, especially at low speeds or for applications with dynamic speed change.
To enable the sensorless vector control, follow these steps:
• Set 00-00=1.
• Set the motor parameters 02-01 and 02-03~02-06.
• Activate the motor auto tune function by setting 02-07=1. During the auto tune function the display will show AT and show END briefly when it is completed,
then the display return to the frequency display.
For more information about the characteristics of the available patterns refer to the description of the parameter 01-00 on the VT1 complete manual I625,

6 ADDITIONAL FUNCTIONS
6.1 PID CONTROL: FUNCTIONS SLEEP AND WAKE UP
For the PID control it is possible to enable the function of sleep and wake up, which allows to decelerate the motor until it stops at the reaching of the PID setpoint value, with consequent energy
saving. The functioning of the sleep and wake up function is showing in the following chart.
• When the PID output frequency falls below the sleep frequency threshold (10-17) for a time longer than the sleep delay (10-18), the motor is decelerated up to 0Hz and the
drive enter in the sleep mode.
• When the PID output frequency returns above the wake up frequency threshold (10-19) for a time longer than the wake up delay (10-20), the drive exits the sleep mode and
automatically reactivates the motor to follow the setpoint.
