Yaskawa AC Drive-P1000 Industrial Fan - Manual (Page 169)

Setting 1: 0.01% (100.00%: Maximum Frequency)
The setpoint and PID monitors are displayed as a percentage with a resolution of 0.01%.
Setting 2: r/min (Set the Motor Poles)
The setpoint and PID monitors are displayed in r/min with a resolution of 1 r/min.
Setting 3: User Defined (Determined by b5-38 and b5-39)
Parameters b5-38 and b5-39 determine the units based on b5-46 setting.
n b5-38, b5-39: PID Setpoint User Display, PID Setpoint Display Digits
When parameter b5-20 is set to 3, parameters b5-38 and b5-39 set a user-defined display for the PID setpoint (b5-19) and PID
feedback monitors (U5-01, U5-04).
Parameter b5-38 determines the display value when the maximum frequency is output and parameter b5-39 determines the
number of digits. The setting value is equal to the number of decimal places.
