MH300 Series

Applications

Machine tools, textile machinery, woodworking, rubber and plastic, winding / unwinding applications

Specifications

• 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

• 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

• 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

• 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
