SLVD servo drives

The SLVD (small, low voltage, digital) drives from Parker measure just 140 x 86 mm with a depth of 140 mm. The family includes models that can deliver shaft powers of up to 620 W.

Designed for direct online operation from a standard 240 VAC main supply, SLVD servo drives are available with a choice of three power output stages, offering current ratings of 1.25, 2.5 and 5 A continuous RMS (2.5, 5 and 10 A peak RMS). High-frequency switching techniques are employed to maximise performance and efficiency, and thereby reduce internal heat dissipation. The drives can be used with any standard 3-phase brushless servomotor that uses sinusoidal commutation and resolver feedback, but are designed for optimum performance with Compumotor's BE, J and NeoMetric series motors.

SLVD servo drives can be used for position, speed or torque control, and are capable of handling simple position control functions such as following, electronic cam profiling and electronic gearbox.

Communications facilities include RS422/RS485 as standard, with CANbus also available. The drive also offers industry-standard step-direction and ±10 V analog control inputs, for users who wish to migrate existing machines to modern servo technology without changing host controllers. In addition to resolver and encoder inputs, the drive features two digital and two analog user-definable inputs, two digital user-definable outputs, and an encoder emulation output. All digital I/O uses PLC-compatible 24 V signal levels for ease of system integration.
