NL i580

High Performance Hydraulic Servo Drive

The IS580, an upgraded product of IS300, is a servo drive developed for high-performance vector control of permanent magnet synchronous motor (PMSM). Using the high-performance vector control technology, it optimizes the process control of injection molding machine, including the control on injection speed and pressure as well as the stability control upon working with the injection holding precision as well as the stability control upon working with the injection molding machine controller. It also provides monitoring software and communication buses and supports multiple encoder types, realizing flexible function combinations and stable performance. The IS580 is mainly applied to such industries as plastic molding, pipe extrusion, shoe making, rubber products, and metal die casting. Compared with IS300, it features better hydraulic control performance, faster pressure and speed responses, lower steady-state pressure fluctuation and smaller size.

Features
Smaller size and higher power density: For models of the same power, the drive size reduces by at least 40% on average.
Wide voltage range: Rated input three-phase 380-480 VAC; Voltage fluctuation range -15% to +10%.
Built-in DC reactor: Provided for models of 30 kW or above, simplifying installation.
Improved built-in braking unit and braking protection functions: Built-in braking unit for models of 75 kW or below (external for 90 kW or above); Equipped with protections including regenerative resistor short circuit, braking circuit overcurrent, braking transistor overload, and braking transistor short circuit.
Longer service life of the bus capacitor: Can serve for a longer time due to better configurations.
Fan drive circuit protection: Generates a protection when the fan is unexpectedly short-circuited due to blocking or damage.
Better drive protection functions: Full series equipped with protections against output short circuit to ground and pre-charge relay (contactor) close fault.
Optimized EMC solution: A complete set of solution can be provided based on actual application requirements and certification requirements.
Matching with 23-bit absolute encoder and support for "auto-tuning free" function: Intelligent identification of motor parameters, with auto-tuning not required when setting up the motor.
