• Trapezoidal Mode (SMA8105/SMA8105HP) - 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. This personality module can be configured for the following three different types of operation: •...
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.

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 SMA8105 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 SMA8105 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...
Chapter Three: Model Numbering 3.1 Introduction: This chapter contains the model numbering system for the SMA8105, SMA8205 and SMA8305 single module, stand alone one axis amplifier and multi-axis applications. The model numbering system is designed so that you, our customer will be able to create the correct model number of the product that you need as quick and as accurately as possible.

NOTE: The multi-axis amplifier label will be mounted on the baseplate and each amplifier module will contain its own label and serial number. 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 SMA8105, resolver for SMA8205 (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.

SMA8105, SMA8205, and SMA8305 MANUAL 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 one or more of the fault LED's are lit, 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. The lowest-level parts or modules which Glentek recommends for field replacement are: 1. Fuses on the GP8600-4000 power supply sub-assembly or the ones on the baseplate.
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 one-day repair service in the unlikely event that your system is down and you do not have a replacement amplifier module.
