Background
Most AML products have a C# API available to allow easy integration of the product into your own application, without having to write an API yourself. The C# APIs provide an easy way to access all aspects of configuration and control of the product. Using the...
Instructions
1. Download the latest copy of the API DLL for your product Visit the product page for your product and look for the C# API download. For example, for the SMD4 visit the link below, and look for the downloads tab at the bottom of the page. https://arunmicro.c...
Axial and Radial Loads
1. Axial and Radial Loads on AML Stepper Motor Bearings AML stepper motors are fitted with two bearings, which support the rotor at each end of the housing. They are extremely reliable in clean vacuum situations and have useful service live...
HV Series Vacuum Stepper Motor User Manual
User manual for AML's HV stepper motors.
Summary and Warnings
AML stepper motors are specifically designed for use in vacuum environments making them ideally suited for low-speed precision in-vacuum manipulation. The model HV motors are two phase hybrid stepper motors, available in a range of standard sizes and torque ra...
Packing
AML motors are vacuum sealed packaged. Wear gloves to remove the motor from its vacuum packaging. Once removed it must be stored in a cleanroom or clean, closed container.
Installation
Use the four holes in the front flange for mounting using the fixings of your choice. The location spigot projecting from the face of the motor is accurately concentric with the shaft and intended for precise location in a recess. Take normal vacuum precaution...
Load Connection
Drive Requirements
Over-Temperature Protection
All AML motors are provided with a K-type Thermocouple (NiCr-Ni) embedded between adjacent windings as standard, or alternatively, the PT100 temperature sensor option. The drive current must be removed when the indicated temperature of the windings reaches 200...
Identifying and Connecting the Leads
Feedthrough Requirements
Preparation of Motor Leadout Wires for use with Other Feedthroughs
Reversal of Rotation
Troubleshooting
If the motor rotates at the wrong speed, frequently changes direction, or has low torque this is probably due to one of the phase connections being open circuit. If the drive indicates that the motor temperature exceeds 200 °C when the motor is not hot, then a...
General Operation Considerations for UHV-Compatible Motors
It is recommended that motors and mechanisms are operated in air during early commissioning. This has the advantage that more cooling is available and that the operator can see and hear that the motor is stepping. Temperature Rise and Run Times The maximum rec...
Firmware Update Troubleshooting
Bootloader could not connect error
If you receive a “Bootloader could not connect” error when updating your device, follow the steps below. 1. Make sure the device is connected to a USB 2.0 port. There are known issues when updating via a USB 3.0 port, particularly with certain driver versions....
