Cautions
• When specifying absolute addresses, set the target address within the range from 0 to the ring value.
Setting a value outside the setting range will cause an error.
• When using Multi Speed operation will absolute addresses, if the total movement magnitude exceeds 32
bits, positioning will stop without continuing operation.
• When changing the current address using the current address change function, set a current address
within the range from 0 to the ring value. Setting a value outside the setting range will cause an error.
• Set the mechanical zero point address within the range from 0 to the ring value. Setting a value outside the
setting range will cause an error.
• The software limit setting is invalid during the ring operation.
• Performing interpolation during the ring operation causes error.
