I have a CU 240 E-2 PN Control unit and a PM 240 Power module in my application. The VFD is used to control a 2 pole motor whose rated speed and frequency are 2800 rpm and 50 Hz respectively. In my application i run this motor for a short duration ( for a few seconds) couple of times a day. In order to increase the productivity i want to increase the motor's maximum speed from 2800 to 3200 rpm.

I know that increasing the motor speed beyond its rated capacity is not advisable. But since the motor runs for a short duration (that too twice a day), i feel that the motor may not get damaged soon. So other than changing P310 and P311 is there any parameter i need to change to acheive this ?

Thanks and regards,

I am using a Induction motor and it is running in speed control.

Thanks for the answer. I will try modifying P1082 and P348 values.
