Code Description
4024 PID SLEEP DELAY
Sets the time delay for the PID sleep function – a motor speed/
frequency below 4023
enables the PID sleep function (stopping the drive).
• See 4023
4025 WAKE-UP DEV
Defines the wake-up deviation – a deviation from the setpoint greater
than this value, for at least the time period 4026
the PID controller.
• Parameters 4006 and 4007 define the units and scale.
• Parameter 4005 = 0,
Wake-up level = Setpoint - Wake-up deviation.
• Parameter 4005 = 1,
Wake-up level = Setpoint + Wake-up deviation.
• Wake-up level can be above or below setpoint.
See the figure:
• C = Wake-up level when parameter 4005 = 1
• D = Wake-up level when parameter 4005 = 0
• E = Feedback is above wake-up level and lasts longer than 4026
