Configurable I/O Application Functions
Logic input application functions
Operating direction : forward / reverse
Reverse operation can be disabled for applications requiring only a single direction of motor rotation.
Reverse operation can be disabled for applications requiring only a single direction of motor rotation.
2-wire control
Run and stop are controlled by the same logic input, for which state 1 (run) or 0 (stop), or a change in state is
taken into account (see the 2-wire control menu).
Run and stop are controlled by the same logic input, for which state 1 (run) or 0 (stop), or a change in state is
taken into account (see the 2-wire control menu).
3-wire control
Run and stop are controlled by 2 different logic inputs. LI1 is always assigned to the stop function. A stop is
obtained on opening (state 0).
Run and stop are controlled by 2 different logic inputs. LI1 is always assigned to the stop function. A stop is
obtained on opening (state 0).
The pulse on the run input is stored until the stop input opens.
During power-up or manual or automatic fault resetting, the motor can only be supplied with power after a reset
prior to the “forward”, “reverse”, and “injection stop” commands.
prior to the “forward”, “reverse”, and “injection stop” commands.
Ramp switching : 1st ramp : ACC, DEC ; 2nd ramp : AC2, DE2
Two types of activation are possible :
activation of logic input LIx
detection of an adjustable frequency threshold
Two types of activation are possible :
activation of logic input LIx
detection of an adjustable frequency threshold
If a logic input is assigned to the function, ramp switching can only be performed by this input.
Step by step operation (“JOG”) :
Low speed operation pulse
If the JOG contact is closed and then the operating direction contact is actuated, the ramp is 0.1 s irrespective
of the ACC, dEC, AC2, dE2 settings. If the direction contact is closed and the JOG contact is then actuated,
the configured ramps are used.
of the ACC, dEC, AC2, dE2 settings. If the direction contact is closed and the JOG contact is then actuated,
the configured ramps are used.
Parameters which can be accessed in the adjust menu :
- JOG speed
- anti-repeat delay (minimum time between 2 “JOG” commands).
- anti-repeat delay (minimum time between 2 “JOG” commands).
