When the grid voltage fluctuates within ±15% of the rated input, the AVR function maintains a constant output voltage to the motor, ensuring consistent torque even under unstable power conditions.

: Reduce the mechanical load on the motor. Check that parameter settings for the motor's rated current ( P01 group ) match the motor's physical nameplate. 6. Maintenance and PDF Support

: Output terminals (connect directly to the 3-phase AC motor). Never connect AC main power to these terminals. (+), (-) : DC bus terminals for external braking units. PB : Braking resistor connection terminal. PE ( ≡triple bar Invt CHE100 Inverter User Manualpdf

Never connect the AC power supply to the output terminals (U, V, W). Doing so will permanently destroy the internal IGBT modules. Environmental Conditions

Set PID target source selection ( PA.00 ), feedback channel selection ( PA.02 ), Proportional Gain ( PA.04 ), and Integral Time ( PA.05 ) to stabilize control loops and prevent system oscillations. 8. Preventive Maintenance and Inspection When the grid voltage fluctuates within ±15% of

Dedicated connections for external braking resistors to safely dissipate regenerative energy. DC Reactor Terminals

: Increase acceleration time ( P0.11 ) or deceleration time ( P0.12 ). Inspect motor windings and cables for phase-to-phase shorts. E.OU1 / E.OU2 / E.OU3 — Overvoltage (+), (-) : DC bus terminals for external braking units

The terminal block layout typically consists of power input, motor output, and braking resistors: Terminal Mark Function Description

: Set to 1 for rotational autotune or 2 for static autotune. 4. Fault Codes and Troubleshooting

Note: After inputting motor parameters, it is highly recommended to perform a motor auto-tuning procedure (Parameter P2.07) to ensure optimal sensorless vector performance. 6. Troubleshooting and Fault Code Reference
