The following section describes I/O signal names and functions of the Servo Driver.
Input Signals
Pin No.
41
Origin proximity input signal:
Origin proximity input signal for origin search connected.
42
Forward rotation drive
prohibited
Reverse rotation drive
43
prohibited
44
Interrupt input signal:
Signal used for interrupt input connected.
45
Origin input signal
47 +
24 V DC control power supply input: Users must provide the
Allowable voltage fluctuation range:
21
Backup battery input:
Connecting pin for the absolute encoder backup battery.
22
Connect to either CN8 or CN1.
Output Signals
Pin No.
31
Alarm: Turns OFF when an error is detected.
32
27
Brake interlock output: Output that controls the brake. The brake is released when this sig-
nal is ON.
28
29
Servo ready: Turns ON if there is no servo alarm when the control/main circuit power sup-
ply is turned ON.
30
37
Alarm code output: Outputs 3-bit alarm codes.
Open-collector: 30 V and 20 mA rating maximum
38
39
Shell
Connected to frame ground if the shield wire of the I/O signal cable is connected to the con-
nector shell.
25
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
26
set in command units (input pulse units defined by the electronic gear).
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.
Function
Overtravel prohibited: Stops Servomotor when movable part
travels beyond the allowable range of motion.
