4.3.3 I/O Signal Names and Functions
The following section describes I/O signal names and functions of the Servo Driver.
„ Input Signals
„ Output Signals
Note 1. Pin numbers in parenthesis () indicate signal grounds.
2. The functions allocated to BKIR, READY, and INP1 output signals can be changed via
parameters. Those output signals can be changed to CLIMT, VLIMT, TGON, /WARN, and
INP2 signals.

Brake interlock output: Output that controls the brake. The brake is released when this sig-
nal is ON.
READY
READYCOM

Servo ready: Turns ON if there is no servo alarm when the control/main circuit power sup-
ply is turned ON.
ALO1
ALO2
ALO3

Alarm code output: Outputs 3-bit alarm codes.
Open-collector: 30 V and 20 mA rating maximum
FG
Shell
Connected to frame ground if the shield wire of the I/O signal cable is connected to the con-
nector shell.
Position INP1
INP1COM
25
26
Positioning complete output 1 (output in Position Control Mode): Turns ON when the num-
ber of deviation pulses reaches the set value. The setting is the number of deviation pulses
set in command units (input pulse units defined by the electronic gear).
