PID SLEEP LEVEL
Sets the motor speed / frequency that enables the PID sleep function – a motor speed / frequency below this level,
for at least the time period 4024
• Requires 4022 = 7
• See figure: A = PID output level; B = PID process feedback.

PID SLEEP DELAY
Sets the time delay for the PID sleep function – a motor speed / frequency below 4023
this time period enables the PID sleep function (stopping the drive).
