ANALOG OUTPUTS No. 2 configurable analog outputs, 12-bit resolution. Possibility of application of
Bias, Gain, Polarity operators. V Out voltage signal proportional to the motor
running speed. I Out current signal proportional to the supplied armature
current (double polarity or positive single polarity only).
DIGITAL INPUTS No. 6 configurable digital inputs for different functions and No. 2 fixed digital
inputs for the START and ENABLE commands. All inputs are optoinsulated
and PLC-controllable with PNP static outputs.
DIGITAL OUTPUTS 5 configurable relay digital outputs. On the digital outputs the following
functions may be programmed: energizing delay, de-energizing delay, positive
or negative logic, hysteresis.
LOCAL MODE
OPERATION For the LOCAL mode operation, the drive may be equipped with a keypad (by
request) with a backlit alphanumeric display, 8 keys and 8 LEDs. The jog,
running / stop and reference reversal commands may also be entered through
the keypad, in addition to the LOCAL mode switching to the ordinary operating
mode stored on EEPROM.
The keypad may be removed or remote controlled. Once the drive has been
set, it may be operated also with no keypad connection. Both 7-segment
displays can be seen through a special slot fitted on the cover of the control
board (together with the four LEDs) for the most important indications.
DRIVE
ADJUSTMENTS The control board is equipped with an EEPROM (non volatile memory) where
all the special parameters of the drive together with the machine adjustments
are stored after automatic tuning procedures or according to the user’s
requirements. The EEPROM is an 8-pin component fitted on a socket which
can be very easily removed and then fitted on an additional board in case of
possible failures, with no need to repeat the machine running procedure.
Possibility of restoring the default parameters or any parameters relating to a
special configuration including prior back-up. Possibility of displaying only the
parameters having a current value different from the default value. Firmware
updating via serial source downloading (using FLASH memory). For more
information, please refer to the DCREG FIRMWARE UPDATING VIA SERIAL
COMMUNICATION manual (P/N 16B0211B1).
PROTECTIONS From output short-circuit: ultra-fast fuses to be fitted externally by the
Customer for DCREG Size 1 … 2A. Already fitted inside in DCREG
