The SMB7275 Analog Brush PWM Servo Drive in the Stand Alone package configuration operates from 60-120 VAC and can output up to 75 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.
|+/-10 VDC for current (torque)
|+/-10 VDC for velocity (RPM)
|Analog tachometer (required for velocity control)
|Single-ended or differential signal command, tachometer, +/- limits, inhibit/enable, fault, reset
|Motor current, fault, low-speed electronic circuit breaker, high-speed electronic circuit breaker, over-voltage, and over-temperature
|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
|2 kHz minimum for current loop and 750 Hertz minimum for velocity loop.
|18 kHz PWM standard.
|Dual mode operation
|Can be configured for current (torque) or velocity (RPM).
|Peak motor current is adjustable.
|RoHS compliance optional.
|All servo drives are CE marked.
|Required for velocity feedback.
|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.
|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.
|Easy access to connections, adjustments, and test points..
|Displays various faults and operating conditions.
|Short circuit protection
|Complete short circuit and ground fault protection.
|Complete optical isolation between signal and power stage.
|Short from output to output, short from output to ground, drive RMS over current, drive under/over voltage, and drive over temperature.
|Provides ultra compact size, cost competitive package and high reliability.
