The SMA5005 Linear Brush Servo Drive in the Module package configuration operates from 24-75 VDC and can output up to 5 A of continuous current. All models can operate in current (torque) or velocity (RPM) mode and accept a +/-10 VDC analog input as a command reference. All models can close the velocity loop via feedback of a DC tachometer. These drives are best suited for low inertia applications that require high bandwidth, low noise, and zero crossover distortion and for motors or voice coils that require high curent loop bandwidths.

| Performance |
| Bandwidth |
All servo drives have a nominal 10 kHz current loop bandwidth which varies with the motor inductance. Higher bandwidths are available upon request. |
| Linear output stage |
Provides high bandwidth, low noise and zero crossover distortion. |
| Multimode operation |
All models can operate in current (torque) or velocity (RPM) mode and accept a +/-10 VDC analog input as a command reference. |
| Heat dissipation |
(@ 25°C): 250 Watts continuous for the SMA5005 and 300 Watts continuous for the SMA5015. |
| Current limit |
Peak motor current is adjustable. |
| Regulatory |
| RoHS Compliant |
RoHS compliance optional. |
| CE Marked |
All servo drives are CE marked. |
| Feedback |
| Tachometer |
Required for velocity feedback. |
| I/O |
| Dedicated inputs |
+/- limits, inhibit, fault and reset. |
| External fault reset |
An input is provided to reset the drive in the event of a fault. |
| Build |
| Fault protection |
Short from output to output, short from output to ground, drive RMS over current, drive under/over voltage (SMA5015 only), and drive over temperature. |
| Status indicator |
7-segment LED display indicates drive status on the SMA5015 and LEDs indicate status on the SMA5005. |
