Pin-Out Description for CDS-3310
Outputs
Amp Enable
Goes high when the amp is turned on (SH) and low when turned
off (MO)
Error
The signal goes low when the position error on any axis exceeds
the value specified by the error limit command, ER.
Output 1-Output 10
These 10 TTL outputs are uncommitted and may be designated by
the user to toggle relays and trigger external events. The output
lines are toggled by Set Bit, SB, and Clear Bit, CB, instructions.
The OP instruction is used to define the state of all the bits of the
Output port.
Inputs
Encoder, A+, B+
Position feedback from incremental encoder with two channels in
quadrature, CHA and CHB. The encoder may be analog or TTL.
Any resolution encoder may be used as long as the maximum
frequency does not exceed 12,000,000 quadrature states/sec. The
controller performs quadrature decoding of the encoder signals
resulting in a resolution of quadrature counts (4 x encoder cycles).
NOTE:
Encoders that produce outputs in the format of pulses and
direction may also be used by inputting the pulses into CHA and
direction into Channel B and using the CE command to configure
this mode.
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.
