Super Servo Driver Card
General
The Super Servo Driver Card was designed to surpass all RC servos for power and efficiency, and with it’s small size (28 x 30 x 9mm), represents probably the best power for size available.
Features
- Small
package (28 x 30 x 9mm)
- Wide
voltage range (6 Vdc to 18 Vdc)
- Powerful,
> 20 Amps continuous, up to 30 Amps cont. with additional heat
sinking, giving a power output of 250 W cont. on 12 Vdc, or 375 W at 18 Vdc.
- 4
kHz PWM (pulse width modulation) output for greater efficiency, and less
heat build up in drive motor and Super Servo.
- Full
digital PD (Proportional/Differential) control circuit, for precise and
accurate positioning.
- Reliable
miniature micro-controller heart for minimum circuitry and maximum
performance.
- Programmable
Failsafe. Servo will return to a user pre programmed position with a failure
of the signal pulse train (~1/2 second without signal)
- Spike
and glitch rejection. Signals more than 10% outside normal range are
ignored.
- Full
buttonless programming, Programming of Proportional Gain, Differential Gain,
Failsafe Position and Feed Back Range, that is required only once, but can
be changed as often as required.
- In
built Receiver Battery Eliminator Circuit (BEC) (5 Vdc 1.5 Amp peak, ~ 0.8 A
cont depending on supply voltage)
- Feed
back by potentiometer 0.5 kW
to 20 kW.
Uses same supply as A to D converter for accurate positioning precision.
- Three
Programmable Feed Back ranges (full range, ½ range and ¼ range) allows for
a number of possible feed back solutions.
- Full
8 bit positioning (256 steps) in all 3 feed back ranges, with high frequency
sampling of servo position (~125 samples/second)
- Signal
requirements are as for std RC receiver output. i.e. 2.5V to 5V, 1
millisecond to 2 milliseconds pulse width at 50 Hz. (frequency can be from
~100 Hz to ~ 3 Hz, without effecting normal operation. However, parts of the
programming sequence which are timed will vary inversely proportional to the
frequency e.g. 10 Hz signal frequency will increase any specified times by
5x)
Signal specifications could be changed if specifically required. Any pulse train, digital or pulse width or frequency could be accommodated, including variable voltage or variable current (eg 0-10V, 0-5V or 4 to 20 mA) at minimal extra cost. Also, pulsed feed back for use as a speed feed back or position count could be accommodated. Just ask.
