Encoder Index, I+ Once-Per-Revolution encoder pulse. Used in Homing sequence or
Find Index command to define home on an encoder index.
Encoder, A-, B-, I- Differential inputs from encoder. May be input along with CHA,
CHB for noise immunity of encoder signals. The CHA- and CHB-
inputs are optional.
Auxiliary Encoder, Aux A+,
Aux B+, Aux I+, Aux A-,
Aux B-, Aux I- Inputs for additional encoder. Used when an encoder on both the
motor and the load is required. Not available on axes configured
for step motors.
Abort A low input stops commanded motion instantly without a
controlled deceleration. Also aborts motion program.
Reset A low input resets the state of the processor to its power-on
condition. The previously saved state of the controller, along with
parameter values, and saved sequences are restored.
Forward Limit Switch When active, inhibits motion in forward direction. Also causes
execution of limit switch subroutine, #LIMSWI. The polarity of
the limit switch may be set with the CN command.
Reverse Limit Switch When active, inhibits motion in reverse direction. Also causes
execution of limit switch subroutine, #LIMSWI. The polarity of
the limit switch may be set with the CN command.
Home Switch Input for Homing (HM) and Find Edge (FE) instructions. Upon
BG following HM or FE, the motor accelerates to slew speed. A
transition on this input will cause the motor to decelerate to a stop.
The polarity of the Home Switch may be set with the CN
command.
Input 1 - Input 8 isolated
Input 9 - Input 16 isolated
Uncommitted inputs. May be defined by the user to trigger
events. Inputs are checked with the Conditional Jump instruction
and After Input instruction or Input Interrupt. Input 1 is latch A,
Input 2 is latch B, Input 3 is latch C and Input 4 is latch D if the
high speed position latch function is enabled.
Latch High speed position latch to capture axis position on occurrence of
latch signal. AL command arms latch. Input 1 is latch A, Input 2
is latch B, Input 3 is latch C and Input 4 is latch D. Input 9 is latch
E, input 10 is latch F, input 11 is latch G, input 12 is latch H.
