Pulse train position command input (see page 16)
• Mode 0 : 90 degree phase difference pulse
(quadrature)
• Mode 1 : Forward/Reverse signal; pulse train
• Mode 2 : Forward pulse/Reverse pulse
Built-in 150 ohm termination resistance can be
turned ON or OFF with DIP switch SWR.
Mode is selected via the pulse mode selection
parameter (P013)

Positioning
completion signal
(Note 2)
POK
Used for position control or
orientation.
Output ON when the position comes
within the specified range (P017).
(Note 3)
Speed deviation
excessive signal
(Note 2)
DSE
Output ON when the real rotation
speed deviation from command speed
exceeds (P027). (Note 3)
Output terminals
Zero speed signal
(note 2)
ZS
Output when the real rotation speed
becomes zero speed detection level
(C063). (Note 3)
CM2
Open collector
outputs
(Configure to an
inverter intelligent
output terminal)
(Note 1): Valid when LAC is assigned to an intelligent input terminal of the inverter (SJ300).
(Note 2): Valid when POK is assigned to an intelligent output terminal of the main body (SJ300).
(Note 3): Refer to the configuration setting procedure for the inverter in the SJ300 Instruction Manual
