Does an F1 occur when accelerating?

If yes,

It may be that the motor is slipping so excessively that torque is not efficiently produced. In this case, it is suggested to increase the acceleration time A1. If increasing the acceleration is unacceptable or does not work, try increasing the voltage boost (A8/C74 on MX™ drives). Increase it gradually in steps of about 0.5%. If raising the voltage boost helped but didn’t completely solve the problem, try gradually lowering the voltage peak function (L21). Do not lower the voltage peak function to less than 90% of its nominal rating. Recall that the nominal voltage peak setting is (Incoming Line Voltage)x(full Hz of motor)/(Full motor voltage).
