• Trapezoidal Mode (SMA8130) - In this mode of operation, which is also commonly referred to as six step, the brushless motor is commutated by hall sensors or an encoder which contains these commutation signals.
Three separate logic inputs can stop the motor in either or both Inputs: directions. Inputs may be configured for active-high or active- low, pull-up or pull-down termination, and a 0 to +5V or 0 to +15V range. Glentek Inc., 208 Standard Street, El Segundo, California 90245, U.S.A.

The servo-loops of a brushless amplifier (figure 2.2b) operate in much the same way, except there are now three current loops, one for each phase of the motor.

Its principal disadvantage is that the large current steps produce high torque ripple. (Torque ripple is a repetitive fluctuation in torque as the motor turns and is independent of load.) The SMA8130 trapezoidal mode amplifier produces a trapezoidal output.
2 The PSEUDO-TACH one shot pulse is buffered and brought to the control interface. The controller can use this signal to determine the exact velocity (RPM) of the motor. The SMA8130 is a trapezoidal brushless amplifier which contains the necessary electronics for motor commutation and also has the PSEUDO-TACH option for better speed control.
Also, there are circuits which limit the motor from running in either or both directions. Glentek Inc., 208 Standard Street, El Segundo, California 90245, U.S.A. (310) 322-3026...

Glentek stocks a complete line of inductors for virtually every application. IMPORTANT: The signal wiring to hall-sensors for the SMA8130, resolver for SMA8230 (if used) and the signal inputs to the amplifier are susceptible to noise pickup. Excessive noise pickup will cause erratic amplifier operation. We urge that each signal input be run in a twisted-pair, shielded cable.

CHAPTER 7: MAINTENANCE, REPAIR, and WARRANTY Chapter Seven: Maintenance, Repair, and Warranty 7.1 Maintenance: Glentek amplifiers do not require any scheduled maintenance, although it is a good idea to occasionally check for dust build-up or other contamination. 7.2 Amplifier Faults: If an amplifier should cease to operate and the fault LED flashes, review the sections which follow on the fault in question for information and possible causes.
The following is a list of possible causes: 1. Binding or stalling of motor shaft due to excessive mechanical overload. 2. Overload of amplifier output to motor. 3. Large reflected load inertia. Glentek Inc., 208 Standard Street, El Segundo, California 90245, U.S.A. (310) 322-3026...
If an amplifier module should fail, simply unplug the pre-amp and plug it into a replacement amplifier. Glentek Inc., 208 Standard Street, El Segundo, California 90245, U.S.A. (310) 322-3026...
5. Return the unit by the best means possible. The method of freight chosen will directly affect the timeliness of its return. Glentek also offers a 24-48 hr. repair service in the unlikely event that your system is down and you do not have a replacement amplifier module.
