Glentek’s Alpha Series Digital PWM Servo Drives offer high performance DSP control of brushless (standard servo and high-speed spindle), brush type, rotary, linear, voice coil and AC induction motors. Both AC powered (stand alone and multi-axis) and DC powered (module) packages are available. These drives incorporate Field Oriented Control (FOC) and Space Vector Modulation (SVM) algorithms which provide optimum control that enable motors to run cooler and at higher velocities.
Set-up, tuning and system diagnostics is accomplished using MotionMaestro (Glentek’s Windows-based software).
Glentek offers three drive models, Resolver-Based (92XX), Encoder-Based (Dual-Board) (94XX), and Encoder-Based (Single-Board) (95XX). The Encoder-Based (Single-Board) models are slightly larger, but lower cost than the Encoder-Based (Dual-Board) model.

Performance | |
---|---|
FOC | All Alpha Series employ Field Oriented Control method which allows accurate control in both steady state or transient operation, and optimal orientation of the magnetic field. |
Space Vector Modulation | Glentek’s advanced algorithms allow for maximum utilization of the DC bus voltage while generating minimum harmonic distortion of the currents in the winding of 3-phase AC motor. |
Digital Current Loops | Current loop bandwidths up to 3 kHz. |
Digitally Tuned | All parameters set digitally. No potentiometers to adjust. DSP control for the ultimate in high performance. |
Parametric Filtering | Provides control engineers advanced filtering to eliminate unwanted system mechanical resonance. |
Smart-Comm Initialization | Eliminates the need for Hall sensor or commutation tracks for many applications. |
Auto Phase Advance | Plug and Play for all types of three phase brushless motors. Provides control engineers the ability to connect any motor to the drive’s motor outputs. The drives smart algorithm will automatically find and align the motor phases to allow for the most optimized smoothness and efficient commutation. |
Sinusoidal Commutation | For the ultimate in efficiency and smooth motion, commutates from almost any resolution linear, rotary encoder, or Hall sensors only. |
Fault protection | Short from output to output, short from output to ground, drive RMS over current, drive under/over voltage, drive over temperature, motor over temperature. |
On-the-fly mode switching | This feature allows the drive to switch between any mode of operation on-the-fly. That is, the drive can switch between current to velocity (or velocity to current), current to position (or position to current), and velocity to position (or position to velocity) while the motor is in motion. This feature is available upon request. Please contact Glentek application engineers for assistance. |
Software configurable | Glentek’s Windows™ based MotionMaestro© software provides ease of set-up, monitoring and tuning with no previous programming experience required. This software is Windows™ 95/98/2000/XP, NT, Vista, 7, and 8 compatible. |
Silent operation | 25 kHz PWM standard. |
Command/Control Modes | +/-10V for current (torque) or velocity (RPM), pulse (step) and direction, encoder follower, external sine commutation (2-phase current mode), RS-232, RS-485, PWM for current (torque or velocity (RPM), and camming/gearing. |
Regulatory | |
CE Marked | All servo drives are CE marked. |
RoHS Compliant | RoHS compliance optional. |
Connectivity | |
RS-232 or RS-485 | High speed (115.2K baud) serial communication interface for setup and tuning and diagnostics.Note: RS-485 is optional. |
Feedback | |
Resolver feedback | Accepts analog signals from all types of resolver feedback (92XX series drives). |
Encoder feedback | Accepts nominal encoder signals up to 5 MHz (maximum frequency of up to 10 MHz is possible, but is system dependent). |
Tachometer feedback | Accepts analog signals from all types of tachometer feedback. |
I/O | |
Dedicated I/O | Analog signal command, +/- limits, inhibit/enable, fault, reset, motor temp, encoder and step & direction. Programmable analog out: 1 12-bit or optional 2 16-bit. General purpose relay: maximum 2 amps @ 30 VDC. Nais P/N: TQSA-5V. |
Input | |
Wide operating voltage | 24-340 VDC for drive modules. All stand-alone and multi axis versions can be ordered for operation from either 110-130 VAC or 208-240 VAC (single or 3-phase, 50/60 Hz). Note: Non-standard input voltages available on request. |
Direct AC operation | The stand-alone units and multi-axis chassis include DC bus power supplies, cooling fans and a regen clamp with dumping resistor. Note: SMX9415-1D-1 Stand Alone does not have a regen clamp. |
External logic supply | 24-48 VDC, 600mA min @ 24 VDC powers all logic & encoder. This works as a “keep alive” for the SMC9415 drives. |
Build | |
Complete isolation | Complete isolation between signal and power stage. |
Non-volatile memory | All parameters are stored in non-volatile memory for reliable start up. In addition, up to four different configurations can be stored in the drive’s non-volatile memory. |
Relay outputs | Two pins provide an interface for the relay. They turn on when a desired condition occurs. |
Status indicator | 7-segment display indicates drive status and diagnostics. |
