ProgCard II - Programming Card for ICE Series ESC Users’ Manual
The advantages are that the P and I gains can be reduced without getting a weak speed control.
Important notice for the governor fine tuning.
he governor software default parameters are adapted to most setups. Nevertheless, if necessary the following parameters (P
and I gain) can be adjusted.
P-Gain is the proportional gain. According to this parameter, head speed variations will be regulated
harder or softer. Practically, it is the force of the control loop. (- weaker, + stronger). With smaller helis, less then 1m rotor
diameter, this parameter shouldn’t exceed 1 meter. With larger diameters you can go to the max. A bad adjustment is
reflected by a wagging tail.
I-Gain is the integral gain. According to this parameter, remaining head speed deviations are corrected faster or slower. It
is an important complement to the P term: The P control is fast, but cannot recover completely the demanded head speed as
it needs this deviation to exist. The I-term remembers this small remaining deviation and is able to remove it completely
thanks to its “memory”
Both parameters should be adjusted simultaneously. If you can increase the P-term, you should generally also be able to
increase the term and vice versa.
Too high settings can lead to a resonance between tail gyro and governor. The result is then a very noisy or even wagging
tail that could lead to an out of control situation.
Therefore the adjustments on P and I should be done in small steps.
By selecting again one of the governor modes, these parameters are reset to their default values.
Startup Speed is the spool up speed for helicopters and planes.
PWM Frequency is the switching rate used for partial load operation. With low frequencies the losses are reduced, but the
motors run slightly rougher. With high frequencies, it is the opposite. The optimum frequency may be found in the user
manual of your motor.
Startup Power. The higher the startup power, the faster and harder is the start. With small propellers it isn’t a problem,
but with large ones, it can lead to a fairly rough startup behavior.
Before you disconnect the ProgCard from the ESC, you can verify your programmed settings by scrolling through each
menu line. But this is only a history of your recent settings and doesn’t reflect the other settings of the ESC. For that you
have to read it in again.
Hint:
When you select a line where all LED¡¯s are off (like the cell count lines) and push Enter, the ESC is really read back
again. This is a way to control again the ESC settings without disconnecting the power. (Works only on BEC ESC’s)
After programming, please disconnect first the flight battery and then reconnect the ESC plug into the receiver.
