Example of rotation in the direction where the current value decreases (BFM #530/#630: 2)
(1-speed positioning operation)
• When the current value is equivalent to the target address, positioning is completed
(and the positioning completion signal turns ON).
• The 20SSC-H cannot position the motor to a value larger than the preset ring value.
When the address is specified in relative value:
• The 20SSC-H positions the motor while regarding the preset target address as a relative movement quantity.
Example of rotation when the address is specified as a relative value
(1-speed positioning operation)
• The rotation direction is forward when the target address sign is "+", and reverse when the target address
sign is "-."
• The 20SSC-H can position the motor to a value larger than the preset ring value.
