10 Start Control
1001 Start \ Stop control
-
2 wire means that you have a single maintained start
contact
- 3 wire means that you have a momentary normally open
start contact and a momentary normally closed stop
contact
- Comm module means the start command will come from
an external device through the communication module
installed

1002 Ramp
-
this is the time that it will take for the current reference to
increase from the Step value (parameter 1003) to 500%
of the motor name plate current (entered in parameter
1301)
- a setting of “0 seconds” will cause the Opal to operate in
constant current mode, this means the current reference
will be set at the Step value (parameter 1003) and will not
change
0 – 60 seconds Read\Write
1003 Step Current
- this is the amount of current (in percent of motor
nameplate current entered in parameter 1301) that will
initially be applied to the motor before the current
reference begins to ramp up to 500%
- this value is usually set as low as possible but still high
enough so that the motor begins to rotate and soon and
the start command is applied
- if the Ramp time is set to 0 (parameter 1002) then this is
the value of current (in percent of motor nameplate
current entered in parameter 1301) that the Opal will be
limited to constantly
20% - 400% Read\Write
1004 IREF (Current Reference)
-
Internal means the current reference is generated
internally from the ramp and step parameters
- Analog In means that the current reference will be taken
from the analog input (0 to 10Vdc = to 0 to 500% of
nameplate current)
- Comm module means the current reference will be taken
from the communication link (0 to 1000 = 0 to 500% of
nameplate current)

1005 Phase Angle
- Internal means the phase angle reference is generated
internally from the current loop
- Analog In means that the phase angle reference will be
taken from the analog input (0 to 10Vdc = to min to max
phase angle)
- Comm module means the phase angle reference will be
taken from the communication link (0 to 1000 = min to
max phase angle)
- Note that when using a phase angle reference from the
analog input or communication link the Opal Pro makes
no attempt to limit current
