motor does not exceed Vmax [rps] velocity.  

Velocity and position can be set with fraction values.

 Motor motion parameters. 

Exemplary for motion parameters Vmin: 0,01; Vmax: 1; Amax: 1 and set position  –  10 revolutions, 
motor will speed up to 1rps velocity at 1 sec. time, will made next 8 revolutions, then will slow down 
to 0rps velocity at 1 sec.  

3.3 Driver configuration by SIC184-KONFIGURATOR program  

For configuration of SIC184 drives is designed SIC184-KONFIGURATOR program, which allows to:  

-

 

Set default parameters of motor motion (minimal and maximal velocity, acceleration) 

-

 

Set parameters of power controller (step division, maximal current, current reduction) 

-

 

Testing of set motion parameters (set velocity, position), set based position  

-

 

Inputs and outputs diagnostics 

-

 

Encoder configuration (activated, deactivated, resolution, testing of encoder connection)
