Data Sheet  
RunInit  
command is received. Furthermore the master has to check  
that the actual position of the stepper motor does not  
correspond to the target position of the first motion. This is  
very important otherwise the circuit goes into a deadlock  
state. Once the circuit is in deadlock state only a hardstop  
command followed by a GetFullStatus1 command will  
cause the circuit to leave this state.  
The Master provides this command to the circuit in order to  
initialize positioning of the motor by seeking the zero (or  
reference) position.  
Once the RunInit command is started it cannot be  
interrupted by any other command, except on the  
occurrence of a condition leading to a motor shutdown (See  
§ 9.2.2.7 Motor Shutdown Mode), or when a HardStop

SetMotorParam  
• minimum velocity for the Stepper-motor (Vmin)  
• acceleration shape (AccShape)  
• stepping mode (StepMode)  
This command is provided to the circuit by the Master to  
set the values for the Stepper motor parameters (listed  
below) in RAM.  
• indicator of the stepper motor reference position (Shaft)  
• acceleration (deceleration) for the stepper motor (Acc)  
• secure position for the stepper motor (SecPos)  
• coil peak current value (Irun)  
• coil hold current value (Ihold)  
• maximum velocity for the stepper motor (Vmax)
