EZ Sleep/Wake-up Function
To enable EZ Sleep/Wake-up functionality on the drive, first set parameter b5-89 to 1. The default setting for b5-89 is 0, which
disables the EZ Sleep functionality and related parameters, except for parameter b5-91, EZ Sleep Minimum Speed.
Setting b5-89 to 1 disables the existing PID Sleep function (b5-15) and enables the EZ Sleep/Wake-up functionality.
EZ Sleep and Minimum Speed Units
Parameter b5-90, EZ Sleep Unit, determines the unit, range, and resolution of parameters b5-92 and b5-93. When set to Hz,
the range is 0.1 to 400.0 Hz. When set to RPM, the range is 0 to 24000 RPM. Changing b5-90 will NOT automatically re-
scale the values of b5-92 and b5-93.
Minimum Speed
Parameter b5-91, EZ Minimum Speed, acts as a lower limit on the PID output. This value is internally limited to the higher
value between b5-34 or d2-02 and is active regardless of the b5-89 setting. When this limit is active, the PID integrator will
be held to avoid integral wind-up. Parameter b5-90 determines whether the value is input in Hz or RPM.
Sleep
When the output frequency (or speed) is at or below the EZ Sleep Level (b5-92) for the time set in EZ Sleep Time (b5-93),
the drive will sleep. The EZ Sleep Level is internally lower limited to the b5-92 setting.
Wake-up using Absolute Level (b5-95 = 0)
For Normal Acting PID, the PID Feedback must drop below the EZ Wake-up Level (b5-94) for the time set in EZ Wake-up
Time (b5-96) in order for the drive to wake-up.
