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 

the terminals 6 & 7 AIN. 

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. 

 

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). 
 
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 the terminals 6 and 7 AIN. 

 

The ‘Internal’ frequency setpoint set by the Control Potentiometer is ADDED 
to the external frequency setpoint (set by either external potentiometer or 
control voltage). 

 

On mains break or fault, the inverter will automatically re-start on power-up 
(Auto restart P1210 = 6 – default).
