1 EDM+P EDM+ output with short-circuit
protection
21 EDM- EDM- output A monitor signal is output to detect a safety function failure.
The Pin No. 22 is reserved.
2 EDM+ EDM+ output without
short-circuit protection
22 SFA Reserved
3 SF1+ SF1+ input 23 SF1+ SF1+ input Inputs 1 and 2 for operating the STO function, which are two
independent circuits. This input turns OFF the power transistor
drive signals in the servo drive to cut off the current output to
the motor.
4 SF1- SF1- input 24 SF1- SF1- input
5 SF2+ SF2+ input 25 SF2+ SF2+ input
6 SF2- SF2- input 26 SF2- SF2- input
7 SFB Reserved 27 NC NC Reserved. Do not connect.
8 /ERR+ Error output 28 /ERR- Error output common If the servo drive detects an abnormality, it outputs an error
(/ALM) and turns OFF the power drive circuit.
9 OUT1+ General-purpose output 1 29 OUT1- General-purpose output 1 common Output functions: Error output (ERR), Servo ready completed
output (READY), Positioning completion output 1/2 (INP1/
INP2), Motor rotation speed detection output (TGON), Torque
limit output (TLMT), Zero speed detection output (ZSP), Speed
conformity output (VCMP), Warning output 1/2 (WARN1/
WARN2), Speed limiting output (VLIMIT), Error clear attribute
output (ERR-ATB), Remote output 1/2/3 (R-OUT1/R-OUT2/R-
OUT3), Zone notification output 1/2 (ZONE1/ZONE2), Posi-
tion command status output (PCMD), Distribution completed
output (DEN).

12 IN1 General-purpose input 1 32 IN2 General-purpose input 2 Input functions: Positive drive prohibition input (POT), Nega-
tive drive prohibition input (NOT), Error stop input (ESTP), Ex-
ternal latch input 1/2 (EXT1/EXT2), Home proximity input
(DEC), Positive torque limit input (PCL), Negative torque limit
input (NCL), Monitor input 1/2/3/4/5/6/7/8 (MON1/MON2/
MON3/MON4/MON5/MON6/MON7/MON8), Main circuit pow-
er supply ON/OFF input (PRDY).
