FEATURES OF THE MX SERVO DRIVE
• MX amplifiers can be connected directly to three phase line power.
• Customizing adjustments to control parameters can be performed and stored in the removable display-
keypad, or serially through the full duplex RS485 serial link.
• Display-keypad module can be transferred, complete with stored personality data, to another amplifier.
• MXP user interactive set up program to speed start up, diagnostics and guarantee correct documentation.
• Provisions for a back-up supply to maintain encoder signals during main power shut-down are available.
• Control circuits are optically isolated from the power circuit.
• Microprocessor digital control of the control inputs and outputs.
• Integrated power supply, shunt circuit, heat sink (and fan as needed).
• The power stage is protected against short circuits, overcurrent, overvoltage, and excessive temperature rise.
• Immediate recall of last-stored or factory default parameter settings. This feature is a considerable advantage
during start-up and commissioning.
• Simulated A/ B/ Z encoder signals with selectable resolution are provided.
• Limit switch inputs, stop-hold, and shaft-orientation functions are available.
• Accel and decel ramps are totally programmable and engage/disengageable.
• Diagnosis is facilitated by fault codes displayed at the keypad and by the MXP program.
• Last-fault function is stored in non-volatile memory for interrogation so it can be recalled even after a power
down may have reset the fault.
• Designed with physical separation between the power connections and control wiring.
• Inrush current limiting circuit to prevent excessive inrush current at power-on.
