u-force with EDRCS (Easy Direct & Remote Controlled Setup)

U means universal, this means separate listed:

• for brushed motors and
• for brushless motors.
• No noticable difference in the startup of 2- and 3-phase motors,
this means particularly brilliant also for those,
who will change the motor from brushed to brushless
without additional costs for the controller.
• for cars and
• for boats.
• for pistol-radios and
• for stick-transmitters.
• robust speed controller for beginners and
• reliable SuperHighPerformance speed controller for champions.
• quick and easy configuration by DIL switch also suited for beginners and
• configuration of all parameters by connecting a PC via a
special adaptor and windows-programm u-soft .
• VirtualDrive-The selectable motor switching frequencies provides unbelievably fine control of speed and braking.
• forward and reverse driving (selectable) in brushless mode.
The u-soft allows configuring an additional proportional braking distance also for the reverse gear.
• SealTec-splash water protected. Therefore off-road qualified.
• ANA-AutomaticNeutralAdjust - easy adjustment by self learning neutral position or by PC-programm.

Additional common specifications:

• AAF-AutoArmFunction (auto-on):
The u-force arms itself automatically, i.e. is ready to drive, when the throttle lever remains on the neutral position for at least 15 (valid and equal) neutral pulses. At this position the controller learns also its neutral point unless the throttle stopp points and end points are fixed (setted) by the u-soft programm. (In this case, the controller also arms in any position of the proportional brake travel.)
• The Auto-Arm function also prevents the motor bursting into life if the transmitter throttle lever is left in a "motor running" position (either direction) when the receiver is switched on (or after a shut-down due to overheating).
• POST-PowerOnSelfTest:
The u-force refuses arming also when the "environment" (motor type, motor windings, battery voltage, battery resistance, cable length and more...) does not allow a reliable operation of the u-force. If possible the u-force beeps an errorcode.

• For competition use any of the limiters (current limiter, torque (softstart) limiter), minimum throttle, minimum brake and maximum brake, neutral deadband are programmable.
• You can set up minimum brake as an automatic brake and thereby save valuable split-seconds!
• Brushed motor mode features a Turbo function for a lightning start! Another chance to gain a valuable tenth of a second or two, and avoid the pile-up on the starting grid when otherwise the controller setup is set to "current saving" mode.

• The selectable motor switching frequencies provides also low current consumption, whilst avoiding premature motor wear and overheating problems.
• In brushless motormode forward- and reverse running is available.
With our u-soft you can configure a proportional brake also for the reverse gear.

• Advanced Low Power RISC-(ReducedInstructionSetCore) microprozessor with 8 MIPS-MillionInstructionsPerSecond:
this means fully micro-processor controlled and monitored: temperature, low voltage, excess voltage, validity of incoming receiver signals, e.t.c..
• Very low losses because of most advanced FETs.
• Power-On-Reset and Power-Off-Reset prevent unwanted bursts of motor power when the battery is connected.

• Drive motor acts as "loudspeaker" to confirm set-up and control functions.
• Brake light output.
• Controllers can be programmed and programmed data selected & modified , using our u-soft via adaptor cable and RS232 port of your PC.
• PPS - PerfectPlugSystem - standard build in pp35 motor connector sockets and pp35 motor plugs supplied
