Bit setting value=0
Monitoring frequency shows absolute value when motor forwards/reverses.
Bit setting value=1
Monitoring frequency shows positive/negative value when motor forwards/ reverses.
F4-15 is bit operation, only set corresponding bit of monitoring frequency = 0/1.
For instance: when motor forwards/reverses, the monitoring output frequency and
estimated slip frequency shows positive/negative value respectively, but monitoring the
other frequency shows absolute value, only set the 0
th
bit=1 (corresponding to the output
frequency) and the 5
th
bit=1 (corresponding to the estimated slip), and set other bits = 0,
i.e. F4-15=XX10X001.
