Product Description
Digital Parameter Function
First Menu SBM51 Gateway (Odd-Numbered Addresses)
Set the FI motor enable via the parameter 2216 “Q digital setpoint 1”.
!
NOTICE
If the parameter
2216 “Q digital setpoint 1”
has not been configured, it is not possible to enable the
motor in automatic FI mode. The motor remains at a standstill.
NOTE
When the value of parameter
2216 “Motor enable”
changes, parameter 2254 can adopt a negative
value.
Motor freewheel stop is activated using parameter
2220 “Q digital setpoint 2”
.
If the value of parameter 2220 is 1, the motor will coast down to a stop. This function has higher
priority than motor enable (parameter 2216). This function has no effect if parameter 2220 has not
been configured. This function is used in conjunction with the motor flying start function (see the
commissioning instructions from Danfoss).
Acknowledging Alarms
Set FI alarm acknowledgment via the parameter
2245 “Q digital setpoint 3”
. Messages are always
acknowledged via the 0/1 edge of the assigned digital signal.
Second Menu SBM51 Gateway (Even-Numbered Addresses)
You can control the first two relay outputs with the SBM51/06 if the Danfoss frequency inverter is
equipped with relay outputs. Relay control is enabled via the parameter
2245 “Q digital setpoint 3”
.
If the value of parameter 2245 is 1, the frequency inverter relay outputs can be controlled via the DDC
system.
Relay 1 is controlled via the
2216 “Q digital setpoint 1”
parameter, relay 2 is controlled via the
parameter
2220 “Q digital setpoint 2”
.
The values of the parameters 2216 and 2220 result in the following relay contact state:
■
“0” or “deleted”
→
Relay is switched
■
“1”
→
Relay is not switched
The DC brake of the frequency inverter is activated using parameter
2246 “Q digital setpoint 4”
.
The value of parameter 2246 has the following effect on the state of the DC brake:
■
“0” or “deleted”
→
The DC brake is switched off.
■
“1”
→
The DC brake is active.
