4. Functions - GM-Racing Purple SX7 Gebrauchsanleitung

Programming the aditional functions with the SET-
Button
All GM-Racing Speed Controllers are fully
programmable. The new 'Easy-Set-System' enables
precise programming within a few seconds.
Program Nr. Function
0 IDA-System (RS232)
1 AMP LIMIT 50-150A
2 Maximum Brake (0 = default to 100%)
3 Automatic Brake (0 to 100% = default)
4 Power curve
Functions
Turbo
When Torque Control / Current Limiting Technology was first used in electronic speed controllers, divers
noticed that the top speed of their cars was also being limited. Ralf Helbing, GM-Racing´s chief
engineer, was the first to incorporate the new TURBO function to his range of speedos to return the lost
speed drivers suffered from. The adjustable turbo function will override your initial Torque Control once
you have used full throttle, and provides you with full power for the main straight on your track. As soon
as you release full power, the speedo will return to your original Torque Control until you reach full speed
again. See graph above. (TURBO (current increase), default = 5A / 17-25ms)
BRAKE MIN
Short for Brake Minimum. This is the percentage of brake that you require for the first stage of brake
travel on your transmitter. By setting this value at 20-40% you will immediately notice the braking effect
for the smallest movement on your transmitter. (default 0%)
BRAKE MAX
Short for Brake Maximum. This is the percentage of brake that you require for maximum brake level on
your transmitter. When racing on slippery surfaces or in wet conditions reduce this value to stop the
wheels from blocking. (default 100%) Most drivers use about 80%.
AUTOBRAKE
Automatic brake is the brake you can adjust for the throttle neutral point of your transmitter.
On some tracks it can be useful to brake the car automatically for faster cornering. (default 0%) Most
drivers use 0-30%.
Frequency
You can adjust 1kHz or 4kHz. The higher frequency is better for the motor and the lower frequency
keeps the speedo cooler.
1kHz = Normal Motor with Brake Low F
4kHz = Normal Motor with Brake High F
All other adjustments on the GMVIS-Commander will set the speedo to 1kHz.
(Default 4kHz)
