Dear,

My client is wishing to display the actual motor speed on the V20 display. The operator does'nt understand the frequency mode. His recipe says him to run the drive at say 1000RPM so with the use of potentiometer he will increase or decrease the speed as required.
Can you guide me with how can I give this feature to him so that I need not have to use RPM indicator. Schneider Make VFD provide them this feature so I have to give them or I will lose my business for this case. Also we have to be sure that once set the drive for the required display setting the operator dont have to touch the parameter setting after every power-up.

Looking forward for positive reply.

Thanks, Smita

I have also checked for the parameter - Scale display frequency - P511 by to my surprise even after it being a float value I am not able to program it in decimal and if there is provision for the divisor then there is a big limitation of the scale range to be 1 to 100. My motor RPM is 2880. how should i feed the multipier as 57.6 or multiplier as 288. Please reply at earliest I am badly stucked.
