PID Delay (ms)
If the PID is enabled, the motor will typically startup as normal without the PID. Meaning, that the
motor start with a duty cycle set with the Min duty cycle parameter, then it will accelerate up
towards the Fixed Speed (%duty) parameter. Once the motor speed exceeds the Min Frequency (Hz)
parameter, the motor will stop accelerating, delay for the PID Delay (ms) time, enable the PID then
accelerate up at the PID Acc/Dec rate until the Fixed Speed (PID Hz) is reached.
This parameter is only used when the PID is enabled.
PID Enabled
A value of 0 = PID disabled, a value of 1 = PID is Enabled.
Changing this value when the motor is running will have no effect. The motor will need to be
stopped to enable or disable the PID.
