Precautions for Correct Use
• This function is enabled when the control method [AA121] is set to 08 (sensorless vector
control), 09 (sensorless vector control in zero speed range), or 10 (vector control with sen-
sor).
• Even if this function is used, the motor may rotate in the reverse direction under a high-load
external force applied in that direction. If you use this function to limit the operation direction,
make sure that the motor would not make reverse rotation.
The system is configured in such a way that the operation can be stopped for safety irrespective of the
operation command until the system allows the operation.
This function becomes enabled when 101[REN] is set to any of the input terminal selections
[CA-01]-[CA-11].
Precautions for Correct Use
The operation does not start if [REN] is set to OFF. To make output from the inverter based on
an operation command in a trial operation, [REN] needs to be set to 000[no] temporarily.
