(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
Code Function
Pulse train position command input (see page 16)
• Mode 0 : 90 degree phase difference pulse
(quadrature)
SAP
• Mode 1 : Forward/Reverse signal; pulse train
SAN
• Mode 2 : Forward pulse/Reverse pulse
SBP
SBN
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)
EAP
EAN
EBP
A, B, Z: rotary encoder signal input
EBN
EZP
EZN
Position control with pulse train input
STAT is valid when STAT is Turned ON.
(Note 3)
Turn ON for orientation operation.
ORT
(Note 3)
Turn ON to cancel LAD.
LAC
(Note 3)
Turn ON to clear position deviation
PCLR
counter. (Note 3)
AP
AN
Retransmits the input encoder signal (ratio 1:1).
BP
BN
EP5 DC +5V power supply
Used for position
orientation.
POK Output ON when the position comes
within the specified range (P017).
(Note 3)
Output ON when the real rotation
DSE speed deviation from command speed
exceeds (P027). (Note 3)
Output when the real rotation speed
ZS becomes zero speed detection level
(C063). (Note 3)
