No. Name Setting Range Default
b5-19 PID Setpoint Value 0.00 to 100.00% 0.00%
n b5-20: PID Setpoint Scaling
Determines the units for the PID Setpoint Value (b5-19) and monitors U5-01 and U5-04. The units for setting and display can
be changed with b5-20.
No. Parameter Name Setting Range Default
b5-20 PID Setpoint Scaling 0 to 3 1
Setting 0: 0.01 Hz
The setpoint and PID monitors are displayed in Hz with a resolution of 0.01 Hz.
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 and resolution used to display the values the setpoint in b5-19, and PID
monitors U1-01 and U1-04.
n b5-21: PID Sleep Input Source
Selects the Sleep Function characteristic action. When b5-21 is set to 1, the Sleep Function Start Level (b5-15) is compared
to the output of the drive (Speed Command after PID Block). Use this setting for open loop control.
The Sleep Function Start Level (b5-15) can be compared to the drive input or setpoint by setting b5-21 to 0.
When b5-21 is set to 2, a variation of the Sleep Function called “Snooze” is enabled. See parameters b5-22 to b5-27 for details.
No. Parameter Name Setting Range Default
b5-21 PID Sleep Input Source 0 to 2 1
Setting 0: PID Setpoint
Setting 1: SFS Input
Setting 2: Snooze
n b5-22: PID Snooze Level
Sets the PID Snooze function start level as a percentage of maximum frequency.
No. Parameter Name Setting Range Default
b5-22 PID Snooze Level 0 to 100% 0%
n b5-23: PID Snooze Delay Time
Sets the PID Snooze function delay time in seconds.
No. Parameter Name Setting Range Default
b5-23 PID Snooze Delay Time 0 to 2600 s 0 s
n b5-24: PID Snooze Deactivation Level
When the PID feedback drops below this level, normal operation starts again. Sets as a percentage of maximum frequency.
No. Parameter Name Setting Range Default
b5-24 PID Snooze Deactivation Level 0 to 100% 0%
n b5-25: PID Setpoint Boost Setting
Temporary increase of PID setpoint to create an overshoot of the intended PID setpoint.
