H8.06 'EAI input polarity setting' defines how the input polarity information can
be used for operation.
● [H8.06] = 0: Polarity inactive
– Setting frequency will be always positive irrespective of H8.16 / H8.18 pa-
rameter setting.
– Direction control is not active in this mode, which means even if negative
frequency command is generated it will result in FWD direction only.
– When frequency source combination is used, the setting frequency from
EAI will be only positive, and can be used in the addition and subtraction
operation.
● [H8.06] = 1: Polarity active without direction control
– Setting frequency will be positive / negative based on of H8.16 / H8.18 pa-
rameter setting.
– Direction control is not active in this mode, which means even if negative
frequency command is generated it will result in FWD direction only.
– When frequency source combination is used, the setting frequency from
EAI can be negative / positive, and can be used in the addition and subtrac-
tion operation.
● [H8.06] = 2: Polarity active with direction control
– Setting frequency will be positive / negative based on of H8.16 / H8.18 pa-
rameter setting.
– Direction control is active in this mode, which means negative frequency
command will result in REV direction and positive frequency command will
result in FWD direction.
– Frequency source combination operation cannot be enabled. As direction
control from EAI is active.
