(3) Setting Monitor Factor
The output voltages on analog monitors 1 and 2 are calculated by the following equations.
<Example>
Analog monitor output at n.00 (motor speed setting)
(4) Related Parameters
Use the following parameters to change the monitor factor and the offset.
Analog monitor 1 output voltage = (-1) × Signal selection
(Pn006=n.00!!)
(Pn552)
Analog monitor 2 output voltage = (-1)
× Signal selection
(Pn007=n.00!!)
× Multiplier + Offset voltage [V]
× Multiplier + Offset voltage [V]
