3-3-3 I/O Circuitry
Outputs (Open Collector Output)
Note Output Circuits:
The pulse output and error counter reset circuitry of the PCU are provided
with two types of terminals: terminals with 1.6 k
Ω
(1/2 W) limit resistance and
terminals with no resistance. Select the terminals in accordance with the
power requirements and the specifications of the motor driver to be used.
!Caution
Connect a load of 7 to 30 mA (or 7 to 16 mA for terminals with 1.6-k
Ω
limit
resistance) to the output section. If a current greater than this is used, it will
cause damage to the PCU’s internal components. Also, be sure to use the
CW/CCW output method when using pulse output terminals with limit resis-
tance.
