•1.0V = signal loss
• 1.5V = end of signal loss
•2.0 mA = signal loss
• 3.0 mA = end of signal loss

of I/O hardware that is present on this drive and is controlled by the inverter.
One of the selections (1=Fault) stops the drive on signal loss. All other choices
make it possible for the input signal to return to a usable level while the drive is
still running.
Sets the highest value to the user-configurable analog input 2 scaling block.

ATTENTION: Setting parameter 324 to a value greater than 1 allows the input
signal to return to a usable level while the drive is running. If a lost analog
signal is restored while the drive is running, the drive ramps to the restored
reference level at the rate specified in Accel Time 1 (140), Accel Time 2 (141),
Decel Time 1 (142), and Decel Time 2 (143). Be aware that an abrupt speed
change may occur depending upon the new reference level and the rate
specified in these parameters. Failure to observe this precaution could result in
bodily injury.
IMPORTANT Note that there is no signal loss detection while the input is in bipolar voltage
mode.
