AVI Zeroing free running to stop
d 2
AVI Zeroing braking to stop and running signals are reserved.
Description of action: A stop signal shall be sent when frequency is set to AVI, parameter is set to 0
or 1 and system has detected that AVI set frequency is 0, AC motor drive shall coast to a stop in
accordance with this setting at the same time; if this parameter is set to 2 and AVI set frequency is 0,
motor stops by braking, but running signals are reserved. Motor shall run continuously when AVI set
frequency rise up again.
Notes: Operation key shall be unavailable when parameter is set to 0 or 1 and AVI input is 0.

The above form suggests that load wave frequency shall influence electromagnetic noise, radiation
as well as interference to the environment of motor; thus, decreasing the load wave frequency shall
help the motor drive to decrease temperature rise if ambient noise exceeds noise of the motor; in
case of high load wave frequency, although operation noise shall be eliminated to a large degree,
attention shall be paid to the interference and protection of the machine.

d 2
2: Fwd run inhibited
If parameter is set to 1” Reverse run inhibited”, REV reference of both the operator and external
terminals shall be unavailable. Even if Rev Run is performed currently, it shall be switched to fwd
run directly. Also, provided that fwd run is inhibited, only Rev run reference shall be performed.
