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
If the drive encounters an error, it will display a fault code on the LED screen.
P0.01 (Source of Run Command): 0 for Keypad, 1 for Terminal Control, 2 for Communication.P0.03 (Max Output Frequency): Usually set to 50.00Hz or 60.00Hz depending on your motor.P0.11 (Acceleration Time): Time in seconds to reach max frequency.P0.12 (Deceleration Time): Time in seconds to reach a full stop.P2.01 (Motor Rated Power): Set to 0.75kW.P2.02 (Motor Rated Voltage): Set to 220V.P2.05 (Motor Rated Current): Set according to your motor's nameplate (typically around 3.5A–4.0A). Troubleshooting Common Fault Codes invt che100-0r7g-s2 manual
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
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 S1 to S4: Multi-function digital inputs (forward, reverse,
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
Before beginning installation, verify that your hardware matches the following electrical ratings: To enter programming mode, press the "PRG" key,
