Integrated Amplifier & PWM Outputs
The unique Mercury^TM concept combines a high performance motion controller and an integrated power amplifier in an extremely small package. Additional PWM control output lines allow the direct operation of all DC-Motor driven PI micropositioning systems, even high speed stages, such as the M-500 ActiveDrive^TM Translation Stages, reducing costs, increasing reliability and simplifying the set-up.

Dual Processor Architecture
The Mercury^TM controller employs a highly specialized processor (LM629) providing high performance PID motion control with many options of trajectory generation and filter settings. Position, velocity and other motion parameters can be changed on-the-fly. For additional system safety and performance, all communication and command parsing processes are handled by a second, independent processor.

Any quadrature TTL incremental encoder can be used for position feedback (linear scales and rotary encoders, interferometers). Limit switch, and origin switch inputs and a motor brake output are standard, too.

Macro Command Language
The Mercury controller offers a high level Mnemonic  Command Language with Macro and Compound command functionality. Macros can be stored in the non-volatile EEPROM for later recall. An auto start macro is available to run automation tasks after power up (no computer communication required!). 

Network Capability 
Up to 6 Mercury^TM controllers can be networked for multi-axis motion control applications. Each set includes software, the C-890.P12 wide range power supply and an RS-232 communicationcable. Slave sets come with a matching slave communication cable and the individual address setting (can also be changed by the user).
