Section 3-4
!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.
Add bypass resistance for loads less than 7 mA.
Outputs (Line Driver Outputs on the CJ1W-NC133/NC233/NC433)
Note
Error counter reset output is open collector output.
!Caution
Connect a load of 20 mA max. to the output section. If a current greater than
this is used, it will cause damage to the PCU’s internal components.
