From the above table, we see that the carrier frequency of PWM output has a significant
influence on the electromagnetic noise, heat dissipation of the AC drive, and the acoustic
noise to the motor.

R
everse Operation Inhibit Factory Setting: d 0
Settings d 0 enable Reverse operation
d 1 disable Reverse operation
d 2 disable Forward operation

The parameter determines whether the AC drive can operate in the reverse or forward
directions.

L
oss of ACI Input Factory Setting: d 0
Settings d 0 Upon the loss of ACI, the drive will default to an output
frequency of 0 Hz.
d 1 Upon the loss of ACI, the drive will stop and display error
message “EF”.
d 2 Upon the loss of ACI, the drive will continue to run at the
last known ACI input.

This parameter is only effective when the Source of Frequency is commanded by a 4 to
20 mA signal. The ACI input is considered lost when the ACI signal falls below 2 mA.

ine Start Lockout Factory Setting: d 0
Settings d 0 enable
d 1 disable

When enabled, the AC drive wil not start when powered up with run commands applied.
To start in Line Start Lockout mode, the AC drive must see the run command go from
stop to run after power up. When Line Start Lockout is disable (also known as
Auto-Start), the drive will start when powered-up with run commands applied.
