Motor or drive has been operated beyond its rated current capacity for too long. Can be caused by mechanical binding or a seized load.

Motor is drawing too much current, check for mechanical blockage.

When multiple inverters are connected on the same network or for long-distance transmission (exceeding 500 meters), the manual recommends connecting a 100~120Ω termination resistor in parallel with the master signal line to enhance noise immunity. The inverter operates as a slave in the network and does not respond to broadcast commands.

The CHE100's capabilities extend far beyond basic motor control. The manual details several advanced features that allow it to integrate into sophisticated automation systems:

Operational Overview and Technical Analysis of the INVT CHE100 User Manual Date: October 26, 2023 Target Audience: Installation Engineers, System Integrators, and Maintenance Personnel

Check motor insulation and wiring. Increase acceleration/deceleration times ( P0.11 / P0.12 ). Verify that motor capacity matches the inverter capacity. OV1 / OV2 / OV3: Overvoltage Protection

. This allows for high-performance control without the need for an external speed sensor, providing a high starting torque of 150% at 0.5 Hz www.efesotomasyon.com Other notable features from the CHE100 manual AVR (Automatic Voltage Regulation):

Includes 4 programmable digital inputs (DI), 2 analog inputs (0–10V or 0–20mA), 1 relay output, and 1 analog output. Installation and Wiring Guidelines

Overvoltage during acceleration, deceleration, or constant speed. LU: Undervoltage (check input voltage). OC1/OC2/OC3: Overcurrent (check motor wiring and load).
