Dear Sir,

 Hi

If the VFD is using the analogue input as a ‘set point’, then it is not using a ‘memory’, of the last setting before stopping.

The only way to reproduce the last setting before shutdown would require a plc for storing that value.

Daer Sir,

I use Digital input for speed variation

Hi

Is this using ‘fixed speed’ settings, set within the VFD, or from a PLC connection?
