NT LIMITATION The DC link voltage and output current limitation are protection functions of the inverter which act on the ramp control according to the P0150 options aiming at containing the rise of voltage on the DC link and of the output current In this way the following of the reference by the ramp is blocked and the output speed follows the 39 Ramp for P0133 or P0134 When the DC link voltage is too high the inverter may freeze hold the deceleration ramp or increase the output speed in order to contain this voltage On the other hand when the output current is too high the inverter may decelerate or freeze hold the acceleration ramp in order to reduce this current Those actions prevent the occurrence of faults F0022 and FOO70 respectively Both protections normally occur at different moments of the inverter operation but in case of occurrence at the same time by definition the DC link limitation has higher priority than the output current limitation There are two modes to limit the DC link voltage during the motor braking Ramp Holding P0150 0 or 2 and Accelerate Ramp P0150 1 or 3 Both actuate limiting the braking torque and power as to prevent the shutting down of the inverter by overvoltage 0022 This situation often occurs when a load with high moment of inertia is decelerated or when short deceleration time is programmed CFW500 11 3 Functions Common to All the Control Modes NOTE
