Description of power section parameters
Parameters
• Type 4: Limit switch left
– First search direction is CCW
– Reference position = First zero pulse or falling edge to the right of the left limit
switch.
– Machine zero = reference position + reference offset
– Reference travel should take place to zero pulse.
• Type 5: No reference travel
– Reference position = current position
– Machine zero = reference offset
• Type 6: Reference cam flush with right limit switch
– First search direction is CW
– Reference position = First zero pulse or falling edge to the left of the reference
cam
– Machine zero = reference position + reference offset
– Note: Reference cam and limit switch must be flush!
• Type 7: Reference cam flush with left limit switch
– First search direction is CCW
– Reference position = First zero pulse or falling edge to the right of the reference
cam
– Machine zero = reference position + reference offset
– Note: Reference cam and limit switch must be flush!
