Synchronous variable-speed drive AMX

asynchronousinductionthree-phase

Overview
The Emotron AMX Series is a general-purpose variable frequency drive for reliable and precise motor control in industrial environments. Compact design, multiple control modes and environmental protection make it suitable for a wide range of applications.

Key benefits

• V/F and field-oriented (vector) control for accurate speed regulation, fast torque response and improved low-frequency performance.
• Rated for ambient operation up to 50°C without derating; conformal-coated boards (3C3) for harsh environments.
• Suitable for variable-torque and constant-torque applications; high starting torque (200%).
• Graphical control panel with high-resolution display: multi-row status, real-time speed/current/voltage/frequency, trend and waveform visualization.
• Built-in monitoring and logic: load monitoring, timers, counters, virtual I/Os and low-voltage sleep to reduce external hardware needs.
• Integrated energy-saving functions and application macros for brake control, multi-pump systems, etc.

Performance and protection

• Ambient operation: -10°C to 50°C (no derating up to 50°C; derating above 50°C to 55°C).
• Conformal-coated PCBs (3C3) for improved moisture/dust resistance.
• Starting torque: 200% for demanding start conditions.
• Overload capability: 120% for 60 s (normal); heavy duty profiles up to 150% for 60 s / 180% for 2 s / 200% for 0.5 s.

Advanced motor control

• Supports asynchronous (induction) and permanent magnet synchronous motors.
• Control modes: V/F control and field-oriented control (FOC).
• Speed control ranges: closed-loop vector 1:1500, open-loop vector 1:200.

Braking and energy handling

• Built-in brake chopper up to 45 kW; optional brake chopper for higher powers.
• Integrated vector braking for controlled stopping and energy handling.

I/O, feedback and communications

• Standard communications: Modbus RTU. Options: RS232, RS485, EtherNet/IP, Modbus TCP/IP, PROFINET.
• Standard control I/O: 7 digital inputs, 2 digital outputs, 3 analog inputs, 2 analog outputs, 2 relay outputs.
• Encoder feedback options: incremental, Sin-Cos, resolver (max one encoder board per drive).
• Motor temperature options: PTC / PT100 / PT1000 board (1 isolated PTC input + 3 PT100/PT1000 inputs).

User tools & commissioning

• Graphical PPU with oscilloscope function for real-time waveform analysis.
• EmoSoftCom PC software via front RS232 for recording signals and backup/load of settings.
• Built-in logic and monitoring reduce need for external control components during commissioning.

Options and expandability

• Optional EMC/EMI filter (C3) for improved electromagnetic compatibility.
• I/O expansion boards (additional relay, analog and digital I/Os).
• Encoder option boards (incremental, Sin-Cos, resolver).
• Real-time clock option for timestamped event logs and calendar logic.
