MCM and MCZ Controllers
An ATF system consists of a sensor (ATF SYS), motion controller (MCM or MCZ) and a motorized "Z" stage. (The Z stage is typically provided by the user.)
The MCZ motor controller integrates the motion controller and the stepper motor drive circuitry. It can drive two-phase stepper motors with a maximum of 1.0 Amp per winding. It is also equipped with two PWM outputs for driving two high intensityLED Illuminators.
In cases where a larger stepper motor is required (exceeding 1.0 Amp per winding), the MCZ controller is recommended. The MCZ controller requires an external stepper motor drive, which is typically provided by the user. The MCZ controller is also equipped with the PWM output for driving a single high powerLED Illuminator.
The diagrams below detail the auto focus servo configurations with MCM and MCZ motion controllers. The system components marked with the tan color are user provided.
