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 b5-34: PID Output Lower Limit
Sets the minimum possible PID controller output as a percentage of the maximum output frequency (E1-04). The lower limit
is disabled when set to 0.00%
No. Name Setting Range Default
b5-34 PID Output Lower Limit -100.0 to 100.0% 0.00%
n b5-35: PID Input Limit
Sets the maximum allowed PID input as a percentage of the maximum output frequency (E1-04). Parameter b5-35 acts as a
bipolar limit.
No. Name Setting Range Default
b5-35 PID Input Limit 0.0 to 1000.0% 1000.0%
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.
No. Name Setting Range Default
b5-38 PID Setpoint User Display 1 to 60000 10000
b5-39 PID Setpoint Display Digits 0 to 3 2
Setting 0: No decimal places
Setting 1: One decimal place
Setting 2: Two decimal places
Setting 3: Three decimal places
n b5-40: Frequency Reference Monitor Content During PID
Sets the content of the frequency reference monitor display (U1-01) when PID control is active.
No. Name Setting Range Default
b5-40 Frequency Reference Monitor Content During PID 0, 1 0
Setting 0: Frequency Reference after PID
Monitor U1-01 displays the frequency reference increased or reduced for the PID output.
Setting 1: Frequency Reference
Monitor U1-01 displays the frequency reference value.
