Local Operating Mode - Santerno DCREG2 Series User Manual

DCREG2
DCREG4
- The LOC REF LED is on if the sources selected for the references are UpDownRef-related only, it
flashes if another source different than UpDownRef is selected, while it is off if none of the sources
selected for the references is UpDownRef-related.
- The BRAKE LED indicates that the electrical braking, or in general the energy regeneration from
the load to the mains, is on.
- The I LIMIT LED indicates that the drive is in current limit. When this LED is on, ILIM LED in the
control board is on as well.

LOCAL OPERATING MODE

As we stated above, the Main Ref can result from the sum of max. four sources:
1. Terminals (Terminal Ref)
2. Up / Down internal reference (UpDown Ref)
3. Serial connection (Serial Link Ref)
4. Field bus (Field Bus Ref)
Similarly, the command sequences (digital inputs) can be simultaneously entered through three sources
selected among the four available sources:
1. Terminals (Terminal Digital Input)
2. Keypad (KeyPad)
3. Serial connection (Serial Link Digital Input)
4. Field bus (Field Bus Digital Input)
MIXED mode: whenever the drive is turned on, the active operating mode depends on the values stored
on EEPROM for parameters C105 ... C108 (RefSelx) and parameters C110 ... C112 (SeqSelx). The
active mode may be inferred by the state of LEDs LOC REF and LOC SEQ. Therefore, Main Ref can
result from the sum of all four available sources, whereas the command sequence (digital inputs) can be
simultaneously entered through max. three of the four sources.
LOCAL mode only: if the "  " and "SAVE" keys are simultaneously pressed - if par. C100 (LocRemSel) is
set at 0:Enabled - the drive will operate in LOCAL mode only for references and commands (i.e. digital
inputs). Therefore, only one selected source is available for the reference, equal to UpDownRef, and only
one source available for the commands equal to KeyPad will be simultaneously selected. In this way, the
run / stop commands may be set only through keypad by pressing the "START" and "STOP" keys. In
addition, the jog run may be set only by means of the "JOG" key, according to the reference value equal to
the one obtained by enabling digital input JogA. The polarity reversal of the Ref n reference applied to the
ramps may be obtained by pressing the
key only.
When this mode is programmed, the display will automatically show the KeyPad page, relevant to par.
M000 (Vref) and to other parameters selected through par. P005 (FirstParm) and P006 (MeasureSel). The
programming mode is already active (as if par. P000 were set at 1:Program Enable). This means that the
UpDownRef reference value can be changed by pressing the increment and decrement keys. When the
KeyPad page is displayed, the programming mode is always active, even though the operating mode is
not the LOCAL mode only. If no source is selected for the UpDownRef reference, the KeyPad page allows
to read the prepared reference only. When the "  " and "SAVE" keys are pressed again, current values for
parameters C105 ... C108 (RefSelx) and parameters C110 ... C112 (SeqSelx) will be reset.
