54 Signal Connections
3.11 Position compare output pin: CMP
The card provides 2 comparison output channels: CMP1 and
CMP2, used by the first 2 axes, 1 and 2. The comparison output
channel generates a pulse signal when the encoder counter
reaches a pre-set value set by the user.
The CMP channel is located on CN2. The signal names, pin num-
bers, and axis numbers are shown below.
The wiring diagram below shows the CMP on the first 2 axes.
NOTE CMP trigger type may be set to normal low (rising edge)
or normal high (falling edge). Default setting is normal
high. Refer to function _8164_set_trigger_type() in sec-
tion 6.16 for details.
The CMP pin can be regarded as a TTL output.
