Introducing Glentek’s next-generation linear servo drives/amplifiers, engineered with a true Class AB output stage that delivers
high efficiency, ultra-low noise, zero crossover distortion, and high current loop bandwidths of up to 15 kHz (load-dependent).
These drives are available in three standard mechanical configurations: Module (DC input), Standalone (AC input), and Multi-axis
(2- and 4-axis, AC input). They support a wide range of feedback devices and provide continuous power output up to 1500 W,
with peak power capability up to 4000 W.
In addition to supporting all standard industry command and control modes, these linear drives uniquely accept motion
commands over both CANopen and EtherCAT communication protocols.
Designed for high-performance motion control applications, Glentek’s linear drives deliver exceptional precision, dynamic
response, and system flexibility—setting a new benchmark in accuracy, reliability, and overall performance.

Here are some key featurers:

High-Speed Current Loop Performance

Nominal 6–10 kHz current loop bandwidth depending on motor inductance

Performance
Bandwidth	All servo drives have a nominal 6-10 kHz current loop bandwidth which varies with the motor inductance. Bandwidth up to 15 kHz is possible with factory tuning and motor inductance.
Linear output stage	True Class AB power stage provides optimal efficiency, zero crossover distortion, and high bandwidth.
Safe Operation Area (SOA)	Advanced SOA algorithm protects the output devices by continually monitoring current, voltage, and temperature in real time.
Hybrid analog/ digital tuning	The current loop is analog and tuned through component selection and jumpers. Velocity and position loops are tuned digitally.
Regulatory
RoHS Compliant	RoHS compliance optional.
CE Marked	All servo drives are CE marked.
Feedback
Encoder feedback	Accepts quadrature feedback up to 40 MHz (10 MHz per channel). By special request only, quadrature feedback up to 100 MHz (25 MHz per channel) may be possible. Absolute serial encoder (BiSS, EnDat, and T-Format). Analog Sin/Cos encoder.
Two feedback devices	We can accept any of the feedback devices listed above plus an additional incremental encoder.
I/O
Programmable Functions	Analog signal command, +/- limits, inhibit/enable, fault, reset, motor temperature, encoder and step & direction.
Build
Status indicator	Two 8-segment displays indicates drive status and diagnostics.
Non-volatile memory	All parameters are stored in non-volatile memory for reliable start up. Note: Available upon request, up to 16 different configurations can be stored in the drives’s non-volatile memory.
Manual reset	A push button reset is available to reset a fault.
Industry standard mounting	Available in a standard heatsink module, large heatsink module w/fan and cover or a 2-axis chassis version. Note: Glentek offers custom mounting configurations to meet virtually any requirement.
Ergonomic Design	Easy access to connections, adjustments and test points.
SMT construction	Provides ultra compact size, cost competitive package and high reliability.
