The digital inputs can be congured for active-high or active-low by setting the Assertion Level
Switch (ALsw) and P120. If wiring to the drive inputs with dry contacts or with PNP solid state
switches, set the switch and P120 to “High” (+). If using NPN devices for inputs, set both to
“Low” (-). Active-high (+) is the default setting.
HIGH = +12 … +30 V
LOW = 0 … +3 V
Note
An F.AL fault will occur if the Assertion Level switch (ALsw) position does not match
the parameter P120 setting and P100 or any of the digital inputs (P121...P123) is set
to a value other than 0.
