These inputs have different
purposes depending on the user
programmed configuration:
Forward and reverse running
command, up to 4 multistage
speed settings, jogging run, 2nd
stage acceleration/decel., free run
stop, external trip, USP function,
terminal software lock, reset,
PTC, input for choosing current
as analog set value

The digital outputs can be user
programmed to provide different
signals for the following
situations:
Signal when reaching set value or
passing a configurable frequency;
signal during motor run;
overload signal;
PID deviation signal; alarm signal
Signal during
motor run
Outputs of
open collector type

Initial setting: During normal operation AL0-AL1 is closed; during a trip
condition
or cut off power supply AL0-AL1 is opened (i.e. AL0-AL2 is closed).
Ratings of relay contacts:
Max. 250VAC / 2.5A (resistive) or 0.2A (cos phi = 0.4); Min. 100VAC /
10mA
Max. 30VDC / 3.0A (resistive) or 0.7A (cos phi = 0.4); Min. 5VDC /
100mA
