The "P.oFF" display is a normal part of the power-on sequence for the CVF-S1 series. It typically appears briefly after power is applied, followed by a "0" display, indicating the inverter is ready for operation. convo inverter cvfs1 manual link
Utilizing space vector pulse width modulation (SVPWM) and open-loop V/F control to stabilize torque across varying loads.
The most direct way to access the user manual is through the following online resources. These sources contain the complete documentation for the CVF-S1 series. At initial bootup, the integrated display panel shows 0
Finding reliable original documentation for legacy variable frequency drives (VFDs) can be challenging. Because the CONVO brand was historically acquired by Bosch Rexroth , many older PDF files have moved to independent engineering databases and social forums.
: Indicates an aggressive acceleration curve or an unexpected mechanical lock on the motor shaft. Increase acceleration times via the parameter panel. It typically appears briefly after power is applied,
When an internal threshold is exceeded, the CVF-S1 locks down its output stage and broadcasts an explicit code on its alphanumeric keypad: E001: Overcurrent Fault during Run
: Key in the exact kW rating, base voltage, operating current, and nominal RPM found on your AC motor's nameplate to ensure accurate sensorless vector performance. Troubleshooting and Error Code Matrix
Ensure input source electricity is disconnected before touching internal parts.
