Code Function
Pulse train input (see page 16)
•Mode 0 : 90 degree phase difference pulse
•Mode 2 : Forward pulse/Reverse pulse
SAP
•Mode 1 : Forward/Reverse signal, pulse train
SAN
ON/OFF of the terminal resistance on the option
SBP
board can be done by the dip switch.
SBN
(Built in terminal resistance 150 ohm)
Mode setting is done at the pulse mode selection
(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)
Turning ON for orientation operation.
ORT
(Note 3)
Turning ON for canceling LAD.
LAC
(Note 3)
Turning ON for clearing position
PCLR
deviation counter. (Note 3)
AP
AN
Outputting the Inputted encoder signal (ratio 1:1).
BP
BN
EP5
DC +5V power supply
EG5
Used for position control or orientation.
POK Output when the subject comes within
the specified range (P017). (Note 3)
Output when the real rotation speed
DSE deviates over from command speed
(P027). (Note 3)
Output when the real rotation speed
ZS becomes zero speed detection level
(C063). (Note 3)
