This document describes the Delta C2000 Series AC Motor Drive, a variable frequency drive designed for various industrial applications.

Function Description:

The Delta C2000 Series AC Motor Drive is a device used to control the speed and torque of AC motors. It achieves this by varying the frequency and voltage supplied to the motor. The drive is designed to provide precise motor control, improve energy efficiency, and protect the motor from various electrical faults. It features a digital keypad (KPC-CC01) for parameter setting, language selection, and trial runs. The drive supports both Normal Duty and Heavy Duty applications, offering flexibility in its use.

Important Technical Specifications:

The C2000 Series offers a wide range of models, each with specific input and output characteristics, as detailed in the nameplate information and model name breakdown.

Model Name Breakdown:
- Series Name: Variable Frequency Drive (VFD)
- C2000 Series: Indicates the product line.
- Applicable Motor Capacity: Ranges from 007: 1HP (0.75kW) up to 4500: 600HP (450kW), with specific details provided in the specifications.
- Input Voltage: Available in 23: 230V 3-PHASE and 43: 460V 3-PHASE.
- Version Type:
  - A: Wall mounted
  - S: Same capacity but miniaturized
  - U: Same capacity but miniaturized (conduit box included)
  - E: Built-in EMI filter
Nameplate Information Example (VFD007C43A):
- Input: 3PH 380-480V 50/60Hz
  - Normal Duty: 4.3A
  - Heavy Duty: 4.1A
- Output: 3PH 0-480V
  - Normal Duty: 3A, 2.4KVA, 1HP
  - Heavy Duty: 2.9A, 2.3KVA, 1HP
- Frequency Range:
  - Normal Duty: 0-599Hz
  - Heavy Duty: 0-300Hz
- Firmware Version: VX.XX
- Enclosure Type: IPXX (specific rating not provided in the example)
- Serial Number: Provides details on production number, week, year, factory (e.g., T: Tauyuan, W: Wujian, S: Shanghai), and model number.
Dimensions (Frames A-H): The manual provides detailed dimensions for various frame sizes (A, B, C, D0, D, E, F, G, H) in millimeters and inches, including width (W), height (H), depth (D), and mounting hole specifications (D1*, S1, Φ1, Φ2, Φ3). These dimensions are crucial for proper installation and space planning. For instance, Frame A (VFD007C43A/E) has dimensions of 130.0mm (W) x 250.0mm (H) x 170.0mm (D). Larger frames like H (VFD4500C43A) can be significantly larger, with widths up to 700.0mm and heights up to 1745.0mm.

Usage Features:

Receiving and Inspection: Upon receipt, users are instructed to inspect the unit for shipping damage, verify the part number against the nameplate, and ensure the wiring voltage is within the specified range.
Installation: The AC motor drive must be installed according to the provided manual.
Pre-Power Check: Before applying power, all connections (power, motor, control board, digital keypad) must be correctly established.
Wiring: Critical attention is drawn to the correct wiring of input terminals (R/L1, S/L2, T/L3) and output terminals (U/T1, V/T2, W/T3) to prevent drive damage.
Operation: After power application, users can select the language and set parameter groups via the digital keypad. Trial runs should begin at a low speed and gradually increase to the desired speed.
RFI Jumper: The drive includes an RFI (Radio Frequency Interference) jumper to suppress electrical noise on the power line. Its removal or retention depends on the grounding system in use.
- Frame A~C: The MOV-PLATE needs to be loosened by screws (torque: 8~10kg-cm) to access the RFI jumper.
- Frame D0~H: The MOV-PLATE can be removed by hand without screws.
Grounding Systems: The manual provides detailed instructions for handling the RFI jumper based on the power distribution system:
- Floating Ground System (IT Systems): The RFI jumper must be removed, and the ground cable disconnected from the internal EMC filter. External RFI/EMC filters should not be installed as they can damage the unit.
- Asymmetric Ground System (Corner Grounded TN Systems): The RFI jumper must be removed in specific configurations (grounding at a corner in a triangle configuration or at a midpoint in a polygonal configuration) to prevent grounding through the RFI capacitor.
- Symmetrical Grounding Power System: The RFI jumper can be used, allowing internal grounding through the RFI capacitor to reduce electromagnetic radiation. An external EMC filter can be installed if higher electromagnetic compatibility is required.

Maintenance Features:

RFI Jumper Handling:
- The RFI jumper should not be removed while the main power is on.
- The main power must be turned off before removing the RFI jumper.
- Removing the RFI jumper cuts off capacitor conductivity, which can lead to gap discharge if transient voltage exceeds 1000V.
- Removal of the RFI jumper compromises electrical isolation, making all controlled I/O low-voltage terminals with basic isolation.
- The RFI jumper should not be removed if the main power is a grounded power system or during high voltage tests (main power and motor must be disconnected if leakage current is too high).
Ground Connection:
- Proper grounding is essential for personnel safety, correct operation, and reduced electromagnetic radiation.
- Grounding cables must meet specified safety regulations regarding diameter.
- Shielded cables must be connected to the Power Regenerative Unit's ground.
- Grounds of multiple Power Regenerative Units should not be connected in series. The manual illustrates the best wiring setup for ground wires.
