Product description:

Delta’s High Performance Compact Drive MH300 series is a new generation micro vector control that inherits Delta’s superior drive technology. With its advantages of outstanding drive performance, strong system support, and a variety of essential functions, the MH300 series is the key to improving market competitiveness and ensuring success. In addition, it features a USB port to make data uploads and downloads fast and easy, which saves the need for additional hardware and provides more installation space for the power cabinet.

Outstanding Drive Performance

  • Overload capacity up to 150% / 60 sec, and 200% / 3 sec. Suitable for constant torque applications
  • Supports induction and permanent magnet motors with optional PG cards for highly precise speed and position control
  • Provides powerful torque output at low frequency (0.5 Hz / 200% without PG vector control; 0 Hz / 200% with PG vector control) for stable heavy-duty operation at low speed and high torque
  • Built-in constant tension control function
  • Speed, torque, and position control

Strong System Support

  • Built-in PLC with 5k steps; Supports system programming to save costs
  • Built-in STO (SIL2 / PL d) safety function and measures for sudden power outages
  • All models can be connected through a common DC bus
  • Built-in Modbus and CANopen interface; optional communication card, including EtherNet/IP, Modbus TCP, EtherCAT, DeviceNet, PROFIBUS DP, and PROFINET
  • Optional models with built-in filter
  • Optional 24V power supply card to reduce unexpected downtime

Flexible Expansion

  • Built-in two 33 kHz high-speed pulse input terminals (MI6 & 7) and one output terminal (DFM)
  • Built-in two accessory card slots for PG card, I/O expansion card, communication card, or 24V power card at the same time
  • Expandable to 3 DI and 3 DO, including 6 ports in total
  • Expandable to 2 or 3 relays

Advanced Tension Control

  • Built-in roll diameter calculation by linear speed, material thickness, and distance meter
  • Two PID parameters: Linearly adjustable to control tension at startup, of small / large rolls, and at high / low linear speed
  • Tension taper calculation: Automatically adjusts tension per the winding roll diameter to avoid wrinkles or deformation
  • Friction and inertia compensation for torque control: Automatically compensates friction and inertia during winding / unwinding for constant tension
  • Automatic roll change by merely using external signal without machine shutdown
