Wiring Servo Relay Units Section 3-4
Upper Terminal Block Pin Arrangement
Lower Terminal Block Pin Arrangement
Note (1) Allocated when connecting an FQM1-MMA21 Analog I/O Motion Control
Module.
(2) Used as the power supply for FQM1-MMP21 pulse outputs or SEN out-
puts for Servo Drivers compatible with absolute encoder.
(3) IN4 to IN11 and OUT0 to OUT7 are used for the servo control signal pow-
er supply.
(4) IN0 to IN3 (interrupt inputs) are used for the latch input power supply.
