•The frequency reference and reversibility depend on whether "16" (AT) is allocated to a multi-
function input, and depend on the combination of A005 and A006, as shown below.
If the frequency reference is "reversible", the motor runs in the reverse direction when "main
frequency reference + auxiliary frequency reference" is less than zero, even if the FW (Forward)
terminal is ON. Also, note that the motor may run in the reverse direction, resulting in prolonged
acceleration time or other phenomena, if the voltage fluctuates around 0 V even with the O2
terminal not connected.
