In the following table the behaviour of the Control Jumpers are
explained:

2.2.3 Default Setup
To change parameters it is necessary to use a Basic Operator Panel
(BOP), Advanced Operator Panel (AOP) or an external serial interface.
The CM411 is therefore delivered with the following default settings:
Setpoint control from the analog input in addition to Control
Potentiometer.
Supply frequency set for 0 to 50 Hz.
Digital inputs:
DIN1 ON/OFF1
DIN2 Reverse
DIN3 Fault Acknowledge.
Jumpers for Ramp and Control circuits set to open. Refer to
previous section for details of jumper settings.
Relay – Fault conditions.
2.2.4 Default Operation
For default operation, connect the control terminals as shown in Figure
6. The default settings of the terminals are described in the table below
Figure 6.
FREQUENCY SETPOINT: - Setpoint addition: Control
Potentiometer and Analog Input (P1000 = 27).
In order to provide the unit with a Frequency Setpoint the user can
either:
1. Turn the Control Potentiometer.
2. Fit an external potentiometer, or apply an external analog control
voltage across terminals 6 and 7.
NOTE
When using the analog input only, the control potentiometer should
be turned fully anti-clockwise to ensure that the control potentiometer
is de-activated.
2.2.5 Operation using "Pot = Run" Jumper
With the "Pot = Run" jumper fitted, the control potentiometer provides
the ON/OFF command source.
In order to provide the unit with a Run command the Control
Potentiometer must be turned in a clockwise direction. To switch the
unit OFF, turn the Control Potentiometer fully anti-clockwise (OFF
position).
WARNING
If the unit is powered up when the Control Potentiometer is not in the
OFF position, the unit may automatically restart and ramp-up to the
frequency setpoint (Auto-restart function is active by default.
