External fault (EF) stop mode
Factory setting
d 1
Setting range
d 0: Reserved
d 1: External fault (EF) coast to stop
Description of action: When EF is detected by the system, a stop signal shall be sent and AC motor shall stop in the
mode of this parameter.

Reference loss detection(Terminal AVI)( stop mode)
Factory setting
d 2
Setting range
d 0: Deceleration stop
d 1: Coast to stop
d 2: Holding operation command after deceleration stop
Description of action: A stop signal shall be sent when frequency is set to AVI, parameter is set to d0 or d1 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 d2 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 d0 or d1 and AVI input is 0

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