Maximum Output Fre- n Press the right and left catches This manual is to be used for the installation, parameter setting, troubleshooting, and daily maintenance of the AC motor drive. Page V, 1. Do not set it to 7, 8, or 9. If any part of V7AZ is missing or damaged, call for service immediately.


Failure to observe this warning f7 result in an elec- trical shock. Motor coasts to a stop at approx. Add to watch list. If the fault re- mains, replace the Inverter. For more information on how to select the sequence polarity, refer to page When a setting range error is found, the constant number where an error occurs is indicated by flashing.

Failure to observe this caution may result in personal injury or a fire. Frequency inverter for full flux vector control. Refer to the table below.

Turn the power ON. Sign in to check out Check out as guest. To output an overtorque detection signal, set one of the output terminal function selections n to n for overtorque detection Setting: Subject to credit approval. Prohibiting reading constants from the Inverter can be set in n Report item – opens in a new window or tab.

Stall Prevention During Deceleration Also, take safety measures such as protection against falls on the machine. Read this manual before attempting to install, operate, maintain, or inspect an Inverter and keep it in a safe.

When the output current goes to the value set for n, acceleration starts. Inverter Software Version The inverter software version can be read out from the monitor parameter U or parameter n The electronic thermal overload function monitors the motor tempera- ture based on Inverter output current and time to protect the motor from overheating.
