Example 2  

Using OFF3 instead of OFF1. 

Set P0701 = 99 to enable BiCo function. 
Set P0840 = 722.0 (On right via digital input 1). 
Set P0848 = 722.0 (OFF3 via digital input 1). 

Now the inverter will ramp between set points using the normal ramp time as set in 
P1120 and 1121. However, at switch off from digital input 1, the inverter will turn off 
with an OFF3, using the ramp rate set in P1135, which may be different to P1121.  
An additional advantage is that the OFF3 function usually requires a second digital 
input; here the BiCo function permits digital input 1 to perform a run right and an 
OFF3. 

Example 3 

Selecting an alternative ramp time when a certain fixed frequency is selected. 
Three fixed frequencies are selected using three digital inputs. 
The digital inputs also select ‘on right’. 
The third digital input also selects the alternative (Jog) ramp times. 

NOTE: 
This will only enable an alternative ramp up time, because, when digital input 3 is 
switched low it will also de-select the alternative ramp time. Normal ramp down 
time will therefore be used. 
 

1 

Use fixed frequencies. 

P1000 = 3 

 

2 

Enable BiCo functionality. 

P0701 = 99 
P0702 = 99 
P0703 = 99 

 

3 

Define source of Fixed 
Frequencies. 

P1020 = 722.1 
P1021 = 722.2 
P1022 = 722.3 

Defines the source of each fixed 
frequency as digital input 1, 2, and 3. 

4 

Define mode of operation. 

P1016 = 2 
P1017 = 2 
P1018 = 2  

Sets the mode of operation of fixed 
frequencies to “select fixed frequency and 
on right command”. 

5 

Select Jog ramp times 
instead of normal ramp 
times. 

P1124 = 722.2 

Enables digital input 3. 

 
NOTE: 
Steps 3 and 4 use BiCo functions to set digital input 1 and 2. This function can also 
be set using normal parameterization in Level 2.
