NUTEC STANDARD PINOUT

The Encoder, Motor and Limit interface connectors are industry standard DB type connectors.  Stage assembly interface gender is male, enabling pin-to-pin connection to our MICROMATIC-9 where female mates are found.

Encoder

Position, Index and Limits

All encoder differential quadrature position and index signals are  RS422 compliant and follow the EIA-422/485 bus interface specification.  RS422 compliance dictates that the composite differential signal logic must fall within the 2 to 6 volt voltage band. Encoder limits used on linear stage assemblies.

HEDs for commutation can be ordered as option.  These pins should otherwise be “No Connect” or not used.

 Pin 19 is used for test purposes and must not be wired.

 Motor

 Three phase brushless servo motors include phases 1, 2 & 3, sometimes called R,S & T. Ground should be connected to amplifier or its chassis ground.

 Limits

External Adjustable

 Three External limits are ordered as option.  External limits can be powered by a 5 up to 24 volts power supply voltage.  Default configuration operates as output Light –ON.   Contact factory for Dark-ON configuration at time of order.

Water Resistant Connection

 For wet process applications water resistant multipole, push-pull latching connectors can be ordered.  They include an inner sleeve and two seals to prevent penetration of solids or liquids into the housing formed by the fixed socket.

WIRE GROUNDING AND SHIELDING

GROUNDING

The Micromatic-9 addresses Position Synchronized I/O for Precision Laser Shuttering and other applications. Using the standard I/O, the Micromatic-9 has high-speed position compare outputs allowing for output control triggered by actual position. The circuit will fire within 100 nsec of reaching the desired position. The position compare output port is enabled by fast CMOS drive technology. Position Compare is programmed deterministically, or non-deterministically in a background process PLC. GUI programmers can read/write from shared RAM for ever changing path and control requirements. No additional hardware is required.

POSITIONER GROUND STRAP

The stage or positioner may itself conduct some signal noise. Attach a ground strap to the stage or position using the provided, un-painted, un-anodized, tapped M4 hole.  The ground strap will provide a drain path to earth ground.

SHIELDING

In general, it is good practice to shield all wires carrying low level signals. This is especially important if the signal level wires are run near power level wiring such as motor wires or relay wires. When shielding wires, connect only one end of the shield, preferably the source end. Connecting both ends of a shield will result in ground loops. It is recommended that the unconnected end of the shield be insulated to prevent accidental connection.
