Fast Position Latch 4 inputs for high speed position capture of axis and master encoder positions

1x 30µsec input, 3x 1ms inputs

Opto-isolated 12-24V

Relay Output Single output for drive enable. Form C (SPDT) relay rated at 24V (150mA)

Common, normally open, normally closed. Fail safe operation: relay de-energized on an error

MicroFlex is a totally digital drive, utilizing a high performance

Digital Signal Processor (DSP) for motor control. A 16KHz Space

Vector Modulation (SVM) and 62.5µS current loop update, ensure

optimal current regulation and dynamic performance for today’s

demanding applications.

By controlling the IGBT power devices using SVM instead of the

more usual carrier based pulse width modulation (PWM), users

can run servo motors at typically 15% higher speeds with reduced

switching losses and harmonics. In today’s world of increased

productivity, this can translate directly into greater machine

throughput.
