In Table 3-2 the behaviour of the Ramp Time Jumpers are explained: 

Table 3-2 

Ramp Time Jumper Behaviour 

No jumper fitted 
Ramp times have arbitrary setting

 

Power down 

 

Fit jumper(s) 

 

Power up 

Inverter uses the ramp times defined by the current 
jumper setting 

At least one Jumper fitted 
Ramp times have arbitrary setting

 

Power down 

 

Power up 

Inverter uses the ramp times defined by the current 
jumper setting 

At least one Jumper fitted 
Ramp times have arbitrary setting

 

Power down 

 

Remove jumper(s) 

 

Power up 

Inverter uses the ramp times that were used before 
removing the jumper(s) 

 
NOTE 
The brake time is influenced by the setting for the ramp time (deceleration time). 
The following relationship applies: 
 
 
 

Control Jumpers (see Table 3-3) are provided for the following functions (fit jumper 
to enable function). Jumpers can only be accessed when the cover is removed: 

 

Pot = Run 
Enables the control potentiometer as the Command Source (auto restart is 
enabled). 

 

24 V AIN   
To change analogue input range from 0 –10 V to 0 – 24 V 

 

DC Brake   
To change Stop function from OFF1 to DC Brake. 

 

Fan/Pump: M~n2    
To change V/f curve from Linear to Quadratic curve. 

 

60 Hz operation 

 

To change motor default settings from 50 Hz to 60 Hz. 

 

Braking time = P1121 (deceleration time)  * 

P0305 (nominal motor current) 
r0207 (nominal inverter current)
