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 DEVIATION
Defines the wake-up deviation –
a deviation from the setpoint greater
than this value, for at least the time period 4026
starts 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 figures:
• 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

4026 WAKE-UP DELAY
Defines the wake-up delay –
a deviation from the setpoint greater than 4025
for at least this time period, re-starts the PID controller.
