EL5-D Series - High Performance 220 / 230 VAC Input Servo Drives

Standard EL5-M motor come with a 2500-line (10000 ppr) encoder. However, motors come with 17-bit (131,072 ppr) high resolution encoders are available for applications require higher precision, smoother movement and lower torque ripple.

Very small velocity ripple can be achieved, percentage error less than 0.1% when operates under 10 rpm.

By adopting load identification and torque feedforward advanced control algorithms, very small velocity ripple and position following error can be achieved. It is a great feature of the EL5 when multi-axis synchronization such as interpolations are required.

Quick response, velocity response (bandwidth) up to 600 Hz.

Vibration suppression technology can suppress vibration occurring at both starting and stopping in low stiffness machine. Suppress vibration frequency up to 1500 Hz, and adaptive filter makes the notch filter frequency automatically follow the machine resonance frequency.

Command signal smoothing can soften the effect of immediate change in velocity and direction, delivering smoother system performance and longer lifetime.

A built-in regeneration resistor (except EL5-D0400) can be used to absorb regenerative energy generated during motor deceleration, improving reliability of the servo systems. For additional protection or more regeneration energy need to be discharged, all EL5 series drives support using external regeneration resistor.
