/i
Type System command
Syntax INVERT_IN(input, on/off)
Description The INVERT_IN command allows the input channels 0..31 to be individ-
ually inverted in software. This is important as these input channels can
be assigned to activate functions such as feedhold.
The INVERT_IN function sets the inversion for one channel ON or OFF.
It can only be applied to inputs 0..31.
Arguments • input
Any valid BASIC expression
Example >>? IN(3)
0.0000
>>INVERT_IN(3,ON)
>>? IN(3)
1.0000

Type Axis parameter
Syntax INVERT_STEP
Description INVERT_STEP is used to switch a hardware Inverter into the stepper
pulse output circuit. This can be necessary for connecting to some step-
per drivers. The electronic logic inside the Trajexia stepper pulse gener-
ator assumes that the FALLING edge of the step output is the active
edge which results in motor movement. This is suitable for the majority
of stepper drivers. Setting INVERT_STEP=ON effectively makes the
RISING edge of the step signal the active edge. INVERT_STEP should
be set if required prior to enabling the controller with WDOG=ON.
Default is off.
Note: If the setting is incorrect a stepper motor may lose position by one
step when changing direction.
Note: This parameter is applicable only to Flexible axis stepper output
axes with ATYPE=46. With other types of axes, this parameter has no
effect.
Arguments N/A
Example No example.
