Control Settings
The following parameters are used to configure the Two Speed
Dahlander Operation Mode and the C445 sources of control.

Soft reset (power cycle) required for changes to these parameters to take effect.
Fieldbus Control Word
The two speed Dahlander motor starter profile will accept
the following control commands over a fieldbus network.
Control Bits
Bit 0/1 00 = Stop command, de-activate all control outputs
01 = Run Slow command, activate Output 1
10 = Run Fast command, activate Outputs 2 & 3
11 = Unknown command, No action
Bit 3 0 = No action
1= Reset fault (will clear fault provided condition
has cleared)
Bit 5 0 = No action
1= The C445 will issue a "Test Trip" fault causing
the Outputs 1-3 control relays to open.
Control Status Word
The control status word of the two speed Dahlander motor
starter profile can be accessed over the fieldbus network.
Status Bits
Bit 0/1 00 = Stopped (No active Run commands)
01= Running1 (Run Slow command is active)
10= Running2 (Run Fast command is active)
Modbus Register Description
700 This parameter selects the Operation Mode
701 Delay time before a control fault is issued. Setting of "0" disables protection.
703 Time delay when transitioning from fast
transitioning to the slow output (in 10ms)
704 Settle delay time before 2
sealed in before activating the fast output (in 10ms)
900 Parameter to set overload full load amps for slow motor winding
901 Parameter to set overload full load amps for fast motor winding
500 This parameter contains the active motor overload FLA rating
(will contain the motor1 setting when on the slow winding and the motor2 setting
when on the fast winding)
1000-1001 Trip (Fault) protection enable bits
Set bits to enable desired motor protections
1002-1003 Warning protection enable bits
Set bits to enable desired motor protections warnings
711 Select the Local Control source.
712 Select the Remote Control source.

contactor is activated – ensures the net contactor is
Bit 2 0 = local control source active
1= remote control source is active
Bit 3 0 = no fault present
1= C445 fault present
Bit 4 0 = no warning present
1= C445 warning present
Bit 5 0 = no inhibit present
1= C445 control inhibit present
Bit 6 0 = C445 not ready (fault and/or inhibit present)
1= C445 ready for control (No fault or inhibit present)
Bit 7 0 = motor is not up to speed (AtRef)
1= C445 has detected motor is up to speed (AtRef)
Two conditions will set the AtRef bit, signaling the motor is
up to speed.
If motor current first exceeds 115% of the active overload
●
FLA rating and then decreases back below 115% of the
active overload FLA rating, it is determined the motor has
come up to speed and the AtRef bit will be set.
If motor current exceeds 30% of the active overload FLA
●
rating and remains until after the start delay time expires
the motor is determined to be up to speed and the AtRef
bit will be set.
