Invt Che100-0r7g-s2 Manual _verified_ May 2026

S1 to S4: Multi-function digital inputs (forward, reverse, multi-speed).+10V, AI1, GND: External potentiometer or 0–10V analog input for frequency control.485+, 485-: Standard RS485 communication ports for PLC integration.RO1A, RO1C: Relay output for fault signaling or status monitoring. Basic Programming and Parameter Settings

OC1 / OC2 / OC3 (Overcurrent): Check for a motor short circuit, heavy mechanical load, or if the acceleration time (P0.11) is too short.OV1 / OV2 / OV3 (Overvoltage): Often occurs during rapid deceleration. Increase deceleration time (P0.12) or install a braking resistor.UV (Undervoltage): Check the input power supply for stability or a loose connection.OL1 / OL2 (Overload): The motor or drive is being pushed beyond its current rating. Check for mechanical jams or reduce the load.OH (Overheat): Ensure the cooling fan is running and that there is sufficient airflow around the heat sink. Safety Precautions

Mounting: Always install the unit vertically to allow for natural heat dissipation.Clearance: Maintain at least 100mm of space above and below the unit, and 50mm on the sides.Temperature: Operate between -10°C and +40°C. If the ambient temperature exceeds 40°C, derate the output current by 3% for every additional degree.Moisture and Dust: Avoid direct sunlight, high humidity (above 95% RH), and corrosive gases. Wiring Diagram and Terminals invt che100-0r7g-s2 manual

The CHE100 utilizes a group-based parameter system. To enter programming mode, press the "PRG" key, use the arrows to find the group, and press "DATA/ENT" to modify. Essential Parameters for Startup

To ensure the longevity of your INVT drive, the installation environment must meet specific criteria: S1 to S4: Multi-function digital inputs (forward, reverse,

Model Number: CHE100-0R7G-S2Rated Power: 0.75 kW (1.0 HP)Input Voltage: Single-phase 220V AC (±15%)Output Voltage: Three-phase 0–220V ACRated Current: 4.0AControl Mode: Sensorless Vector Control (SVC) or V/f ControlProtection Rating: IP20 Installation and Environment Guidelines

L, N: Connect your single-phase 220V AC power supply here.U, V, W: Connect these to your three-phase motor. (Note: Never connect input power to these terminals).(+) , (-): DC bus terminals for external braking units (if required).PE: Grounding terminal. Ensure a solid connection to prevent electromagnetic interference (EMI). Control Circuit Terminals Check for mechanical jams or reduce the load

Proper wiring is the most critical step in preventing drive failure or electrical hazards. Main Circuit Terminals
