Galil DMC-1400 Manuale Utente

FUNCTION:  Home 

DESCRIPTION: 

The HM command performs a three-stage homing sequence for servo systems and two stage 

sequence for stepper motor operation.   

For servo motor operation,  the first stage consists of the motor moving at the user 

programmed speed until detecting a transition on the homing input for that axis.  The 
direction for this first stage is determined by the initial state of the Homing Input. Once 
the homing input changes state, the motor decelerates to a stop. The state of the homing 
input can be configured using the CN command. 

The second stage consists of the motor changing directions and slowly approaching the 

transition again.  When the transition is detected, the motor is stopped instantaneously.. 

The third stage consists of the motor slowly moving forward until it detects an index pulse 

from the encoder.  It stops at this point and defines it as position 0. 

For stepper mode operation, the sequence consists of the first two stages.  The frequency of 

the motion in stage 2 is 256 cts/ sec.
