 NOTE: CHOOSE WHICH SIMULATION TO USE 

 

During simulation with feedback, the movement speed of the transplanting bodies is controlled by 
the rotary encoder that detects the speed of the transmission shaft. This simulation can be useful 
for observing the movement mode and speed of the transplanting bodies at different travel speeds. 
It can also be useful for diagnosing any faults in the rotary encoder of the transmission shaft (or its 
wiring): if the signal is not detected correctly, the system does not control the speed correctly. In 
this case, if the alarms are enabled, the relative alarm will be shown. 

 

During simulation without feedback, the proportional valve that controls the speed of the 
transmission shaft is excited with a constant voltage that can be set. Encoder signals are not used 
in any way. This simulation can be useful for evaluating actual operation of the hydraulic motor, the 
proportional valve, the hydraulic system and the mechanical system. Furthermore, this mode can 
be useful for diagnosing any mechanical hardenings as well as if rotation is sufficiently constant. 

 

None of these two simulations engage the rotary encoder mounted on the wheel (or on the roller) 
that detects the travel speed. 

 

LCD screen contrast (LCD Contrast) 

Indicates  the  LCD  screen  contrast  value:  the  reference  value  goes  from  a  minimum  of  0  to  a 
maximum of 10. The higher the value, the higher the contrast.

 

 
 

 

 

Number of wheel encoder pulses per metre (Encoder Wheel) 

Indicates the number of wheel encoder pulses corresponding to one metre travelled by the machine. 

 

 

This parameter is calculated with the following formula: 

 

 

 Multiplication by 2 is due to the 2 encoder phases. If there are other transmission ratios between 
the wheel gear and the encoder gear, these must be taken into account when calculating the 
parameter.
