Analog Brush PWM Series

Glentek offers the latest in high performance Analog PWM (Pulse Width Modulated) servo drives for the control of both DC brush servo motors and voice coil motors. With extensive utilization of surface mount technology and special heat transfer techniques, Glentek’s SMA7110, SMA7115, SMB7230, SMB7245, SMB7275, and SMB72100 model drives offer one of the world’s most powerful products for a given form factor.

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 an analog tachometer. They provide a range of continuous currents from 6 amps to 100 amps and peak currents from 12 amps to 150 amps. Operating voltages range from 30-220 VDC for Module configurations or 110-130 VAC for Stand Alone and Multi-Axis configurations.

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
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.
