The SMA7110 Analog Brush PWM Servo Drive in the Multi-Axis package configuration operates from 110-130 VAC and can output up to 10 A of continuous current. All Analog Brush PWM Servo Drives use +/-10 VDC for current (torque) or velocity (RPM) control and can accept tachometer feedback.
| Command/Control Modes |
| +/-10 VDC for current (torque) |
| +/-10 VDC for velocity (RPM) |
| Feedback |
| Analog tachometer (required for velocity control) |
| Dedicated Inputs |
| Single-ended or differential signal command, tachometer, +/- limits, inhibit/enable, fault, reset |
| Dedicated Outputs |
| Motor current, fault, low-speed electronic circuit breaker, high-speed electronic circuit breaker, over-voltage, and over-temperature |
| Environmental Conditions |
| Storage Temperature: -40°C to 80°C |
| Standard Operating Temperature: 0°C to 40°C without current derating, up to 50°C with 25% current derating |
| Special Operating Temperature: -40°C to 40°C without current derating, up to 50°C with 25% current derating |
| Humidity: 5% to 95% relative humidity, non-condensing |
| Altitude: Up to 1000m without derating, derate current 10% per 1000m above 1000m |
| Performance |
| Frequency response |
2 kHz minimum for current loop and 750 Hertz minimum for velocity loop. |
| Silent operation |
18 kHz PWM standard. |
| Dual mode operation |
Can be configured for current (torque) or velocity (RPM). |
| 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 |
| Dual signal inputs |
One single-ended and one differential. Both inputs may be used simultaneously. Both have up to 15,000 A/V gain (velocity mode), and inputs will accept the typical +/-10 VDC analog signal. |
| +/- Limits and inhibit |
Three separate logic inputs can stop the motor in either or both directions. Inputs may be configured for active-high or active-low, pull-up or pull down termination, and a 0 to +5 VDC or 0 to +15 VDC range. |
| Fault input/output |
Open-collector output goes low in the event of a fault. Forcing the fault terminal low will inhibit the drive. The fault terminals outputs in a multi-axis system may be connected together to shut down all drives should any drive have a fault. |
| External fault reset |
Can reset drive externally in the event of a fault condition. |
| Build |
| Ergonomic design |
Easy access to connections, adjustments, and test points.. |
| LED diagnostics |
Displays various faults and operating conditions. |
| Short circuit protection |
Complete short circuit and ground fault protection. |
| Complete isolation |
Complete optical isolation between signal and power stage. |
| Fault protection |
Short from output to output, short from output to ground, drive RMS over current, drive under/over voltage, and drive over temperature. |
| SMT construction |
Provides ultra compact size, cost competitive package and high reliability. |
