: Includes three curve types: constant torque, decreasing torque 1, and decreasing torque 2.
: Reduce the mechanical burden on the machine, verify the nameplate FLA matches parameter H-33 , or upgrade to a higher-capacity VFD and motor. E.OH (Inverter Heatsink Overheating)
Troubleshooting and Diagnostics A troubleshooting section lists common fault codes, probable causes, and corrective actions—covering issues like no output, frequent inverter shutdowns, battery charging faults, or communication failures. Diagnostic flowcharts help technicians systematically isolate problems using onboard indicators and multimeter measurements. For complex faults, the manual recommends contacting authorized support and provides necessary data to collect before service calls. Convo Inverter Cvf G3 Manual
Hook up the physical AC motor leads exclusively to terminals U/T1, V/T2, and W/T3 .
Connect incoming 3-phase AC line voltage here. Phase sequence is arbitrary. Do not connect input power to output terminals, as this will destroy the internal components. : Includes three curve types: constant torque, decreasing
Causes: Drive or motor is undersized for the load application, or V/F curve is improperly set.
Multi-function digital inputs (factory defaults often set S1 for FWD and S2 for REV). Relay output for status monitoring (AC 250V/3A). Safety & Installation Environment: Connect incoming 3-phase AC line voltage here
Ensure adequate ventilation space around the chassis. If the drive operates inside a sealed cabinet, you must integrate an auxiliary cooling fan.
: Issues a deceleration stop command or clears latched system faults once the underlying error condition is resolved.
: All wiring and maintenance should be performed by a professional electrical engineer.
Connect the target AC motor leads exclusively to terminals . Never connect incoming AC mains directly to U, V, and W, as doing so will permanently destroy the internal IGBT modules.
