INTRODUCTION

This section describes the main checks and operations which should be carried out to achieve an
excellent adjusting of the DCREG drive.
All information contained herein is directed to the Users being already familiar with the use of the keypad.
If need be, refer to the KEYPAD AND ALPHANUMERIC DISPLAY section for further information.
For a clearer drive operation, the drive operating mode is supposed to send references and control
sequence to inputs by means of the terminal board.
This section has to be considered as a simple and useful guide aimed at achieving a proper adjusting of
the device. It covers both the regulations regarding the most common applications and the setting up of
more specific configurations.
For further information about the function of the different hardware terminals or software parameters and
any additional details, refer to the specific sections of the manual.
In particular, it is strongly recommended to refer to the POWER CONNECTIONS and SIGNAL
CONNECTIONS sections for a correct use of the hardware terminals, as well as the BLOCK DIAGRAM
and the PARAMETER LIST section for a proper setting of the software parameters.

PRELIMINARY CHECKS

2.2.1 When installing the equipment, carefully read the information given on the stick-on plate fitted on
the front panel and make sure that the supply voltage value required to supply the power section at bars
L1-2-3 does not exceed the maximum value advised (standard value: 440 Vac for DCREG2 and
DCREG4). Check also that the supply voltages for the field regulator on terminals E1-2 and for the
control section on terminals 53-54 is included within the suggested range.
Of course, the latter requirement shall not be necessary whenever the user is going to supply the control
section with a 24 Vdc direct voltage on terminals 40-42. This is always possible even without making any
hardware modification.
NOTE
2.2.2 Check also that the device is not oversized compared to the motor rated current. That means that
the motor current value should not be lower than the 75% of the device rated current.
2.2.3 Carefully inspect the wiring by referring to the POWER CONNECTIONS and SIGNAL
CONNECTIONS sections of this manual. In particular, make sure that a NO auxiliary contact of the KM
contactor has been connected in series with the ENABLE contact on terminal 24.
2.2.4 Connect the shield of the screened cables relating to the analog signals to the ground potential as
directly as possible. Use the three collar-shaped cable fasteners situated on the bottom of the control
board supporting guard.
The standard equipment may be supplied on terminals 53-54 (control
section) with a single-phase alternate voltage between 380 ... 500 Vac. On
demand, the device may be supplied on terminals 53-54 a with single-phase
alternate voltage between 200 ... 240 Vac.
The standard equipment may be supplied through terminals E1-2 (field
regulator) with a single-phase voltage ranging from 200 to 500 Vac.
