4. Maintenance Features

The VFD-ME300 Series is a Variable Speed Drive (VSD) designed for controlling the speed of electric motors. It supports both single-phase and three-phase input power, converting it to a three-phase output for motor operation. The device is suitable for a range of applications, including general purpose, fan and hydraulic systems, and those requiring high starting torque.

Function Description:

The VFD-ME300 Series functions by converting incoming AC power to a variable frequency and voltage output, which in turn controls the speed and torque of a connected three-phase motor. It can accept a single-phase input (connecting Live to R and Neutral to S) or a three-phase input (connecting L1/R, L2/S, L3/T). The motor connections are made to U/T1, V/T2, and W/T3.

The drive offers various control methods for speed variation and operation:

• Remote On/Off and Speed Variation: This can be achieved by connecting external terminals. For remote start/stop, connections are made between DCM (common) and MI1 (FWD) and MI2 (REV). For remote potentiometer control, the potentiometer is connected to +10V, AVI, and ACM (common).
• External Terminal Control Circuits: The device supports 2-wire and 3-wire operation control.
  • 2-wire operation (Pr.02-00 setting value 1 or 2):
    • Setting 1 (FWD/STOP, REV/STOP): MI1 controls FWD/STOP (OPEN: STOP, CLOSE: FWD), and MI2 controls REV/STOP (OPEN: STOP, CLOSE: REV).
    • Setting 2 (RUN/STOP, FWD/REV): MI1 controls RUN/STOP (OPEN: STOP, CLOSE: RUN), and MI2 controls FWD/REV (OPEN: FWD, CLOSE: REV).
  • 3-wire operation (Pr.02-00 setting value 3): MI1 controls RUN (CLOSE: RUN), MI3 controls STOP (OPEN: STOP), and MI2 controls REV/FWD (OPEN: FWD, CLOSE: REV).
• Digital Keypad Control: The device features a keypad for local control, including a potentiometer for frequency control, Run key, UP & DOWN keys for numerical changes, Mode key for display changes, STOP/RESET key for stopping operation and resetting faults, and an ENTER key for saving parameters.
• Multi-function Relay Output: Terminals RA, RB, and RC provide multi-function relay outputs (Resistive Load 250VAC/3A N.O., Inductive Load 250VAC/1.2A N.O.).
• Multi-function Output Terminal (MO1): Provides a 48VDC/50mA output.
• Analog Multi-function Output Terminal (AFM): Provides a 0-10V output.
• Modbus RS-485: Supports communication for remote control and monitoring.
• Safety Function: Includes terminals for ESTOP, Safety PLC, and +24V, S1, S2 for safety circuit integration. A short-circuiting jumper is installed between +24V, S1, and S2 as a factory setting for safety function.

Usage Features:

• Quick Setup: The device provides a quick setup procedure for variable speed drive operation. This involves setting parameters such as:
  • 00.02: Reset to factory settings (for 50Hz, set to 9).
  • 00.20: Source of master Frequency Command (0=UP/DOWN arrow, 2=External analog input, 3=External UP/DOWN terminals, 7=Digital keypad potentiometer).
  • 00.21: Source of master Operation Command (0=Digital keypad, 1=External terminals).
  • 01.00: Maximum Frequency required.
  • 01.01: Match Hz on motor nameplate.
  • 01.02: Match voltage on motor nameplate (Max Voltage output).
  • 01.10: Upper limit Frequency.
  • 01.11: Lower limit Frequency.
  • 01.12: Acceleration time (factory setting 10sec).
  • 01.13: Deceleration time (factory setting 10sec).
  • 05.01: Motor Name Plate Current.
  • 05.02: Motor Name Plate kW.
  • 05.03: Motor Name Plate Speed (rpm).
  • 05.04: Number of poles of the motor (3000rpm=2pole; 1500rpm=4pole; 1000rpm=6pole; 750rpm=8pole).
  • 05-00: Auto tuning (option 1 for dynamic test for induction motor, 2 for static test for induction motor). Auto tuning should only be performed after all other data is entered and the motor is unloaded for dynamic test.
• Display and Indicators:
  • Status Display: Shows the drive's current status.
  • LED Display: Indicates frequency, voltage, current, and user-defined units.
  • Keypad Functions: The keypad displays various information including present frequency setting (F60.0), actual frequency output (Fwd: 450.0), user-defined output (018), load current (8 5.8), forward command (Fra), reverse command (rEv), count value (208), parameter item (Fwd: 06.00), parameter content (10), external fault (EF), successful parameter setting (End), and input data error (Err).
• Wiring:
  • Single-phase input: Live to R, Neutral to S.
  • Three-phase input: L1/R, L2/S, L3/T.
  • Motor connections: U/T1, V/T2, W/T3.
  • For single-phase supply VFDs, the motor must be connected in DELTA. For three-phase supply VFDs, consult the motor name tag for 400V connection.

Maintenance Features:

• Fault Protection: The device includes a protective circuit at RB-RC. In case of a fault, the contact switches to ON to shut off power and protect the system.
• Error Indication: The keypad displays "Err" for input data errors or when data is not accepted/exceeded.
• Parameter Reset: Parameter 00.02 allows all parameters to be reset to factory settings for 50Hz.
• Qualified Installation: Wiring and connection must be carried out by a registered electrician. Connection by an unqualified person voids the warranty.
• Motor Suitability Check: Users must check the suitability of the motor before attempting to connect it to the device.
