Compact Variable Speed Drive | Delta MS300 Series

The MS300 series of compact variable speed drives are designed for efficiency while still maintaining a high performance consistent with previous models. In addition to the size being reduced by approx 40% compared to previous versions, the MS300 comes with useful built in functions, including: PLC, USB port, STO function, RS-485 modbus, and a communication slot for various optional communication cards that can be selected to suit specific applications and requirements.

The MS300 supports IM as well as PM motors and can simultaneously host four independent induction motor control parameter sets; in comparison traditional drives can only support the control parameters of a single motor at a time.

Operational Characteristics:

• Supports open loop control of IM and PM motors.
• Output Frequency: 0-1500Hz (High speed version) (v/f control) , 0-599Hz (standard version).
• Dual Rating Design: 120% for 60 seconds for Normal Duty (ND), 150% for 60 seconds for Heavy Duty (HD).
• Built in PLC capacity with 2K steps capacity.
• Built in brake chopper for entire series.
• Removable 5 digit LED keypad for remote operation.
• Safety Standard Compliance: Safe Torque Off (SIL2/PLd).
• Compact design/housing and supports side by side installation.
• Multi-Motor Control: Supports 4 build in independent induction motor control parameter sets.
• Optional built-in Class A (C2) standard EMC filter for 1-phase 230V, 3-phase 460V models.
• One high speed pulse input terminals MI7 built-in with max speed up to 33kHz.
• One high speed pulse output terminals DFM built-in with max speed up to 33kHz.
• PCB coating for circuit and thermal design suitable for harsh environment applications (IEC 60721-3-3 class 3C2).
• One Built-in I/O Communication Card Slot: CANopen, PROFIBUS DP, DeviceNet, MODBUS TCP, EtherNet/IP.
