(2) Output Signals
Note: 1. Pin numbers in parentheses () indicate signal grounds.
2. The functions allocated to /TGON, /S-RDY, and /V-CMP (/COIN) can be changed by using the
parameters. /CLT, /VLT, /BK, /WARN, and /NEAR signals can also be changed. Refer to 8.3.3
Output Circuit Signal Allocation.
Signal Name Pin No. Function Reference

ALM+
ALM- 31
32 Servo alarm: Turns OFF when an error is detected. 9.13.1
/TGON+
/TGON- 27
28 Detection during linear servomotor movement: Detects when the linear servomotor is
moving at a speed higher than the motor speed setting. Detection speed can be set by
using the parameters. 9.13.3
/S-RDY+
/S-RDY- 29
30 Servo ready: ON if there is no servo alarm when the control/main circuit power
supply is turned ON. If “without hall sensor” is set, the magnetic polarity detection
must be completed. 9.13.4

Phase-A signal Converted two-phase pulse (phases A and B) encoder output
signal and zero-point pulse (phase C) signal: RS-422 or the
equivalent
(Proper line receiver is SN75175 manufactured by Texas
Instruments or the equivalent corresponding to MC3486.) 7.3

Alarm code output: Outputs 3-bit alarm codes.
Open-collector: 30 V and 20 mA rating maximum 9.13.1
FG Shell Connected to frame ground if the shield wire of the I/O signal cable is connected
to the connector shell. −
Speed /V-CMP+
/V-CMP- 25
26 Speed coincidence (output in Speed Control Mode): Detects whether the motor
speed is within the setting range and if it matches the reference speed value. 9.7.8
Position /COIN+
/COIN- 25
26 Positioning completed (output in Position Control Mode): Turns ON when the
number of positional error pulses reaches the value set. The setting is the number of
positional error pulses set in reference units (input pulse units defined by the elec-
tronic gear). 9.8.5

The functions allocated to /TGON, /S-RDY, and /V-CMP (/COIN) can be changed by
using the parameters. /CLT, /VLT, /BK, /WARN, and /NEAR signals can also be
changed. 9.11.5
