When the torque reaches the torque limit value during torque generation, TLC will turn on. When
the servo is off, TLC will be turned off.
This device cannot be used in the torque control mode.
When warning has occurred, WNG turns on. When a warning is not occurring, WNG will turn off in
2.5 s to 3.5 s after power-on.
BWNG turns on when [AL. 92 Battery cable disconnection warning] or [AL. 9F Battery warning] has
occurred. When the battery warning is not occurring, BWNG will turn off in 2.5 s to 3.5 s after
power-on.
CDPS will turn on during variable gain.
ABSV turns on when the absolute position is undetermined.
The device cannot be used in the speed control mode and torque control mode.
When a tough drive is enabled in [Pr. PA20], activating the instantaneous power failure tough drive
will turn on MTTR.
CLDS turns on during fully closed loop control.
Connector
pin No.
CN3-6 These devices output pulses of encoder output set in [Pr. PA15] and [Pr. PA16] in the
differential line driver type.
CN3-16
In CCW rotation of the servo motor, the encoder B-phase pulse lags the encoder A-
phase pulse by a phase angle of π/2.
CN3-7
The relation between rotation direction and phase difference of the A-phase and B-
CN3-17
phase pulses can be changed with [Pr. PC03].
Output pulse specification, dividing ratio setting, and electronic gear setting can be
selected.
CN3-8 The encoder zero-point signal is output in the differential line driver type. One pulse is
output per servo motor revolution. This turns on when the zero-point position is
CN3-18
reached. (negative logic)
The minimum pulse width is about 400 μs. For home position return using this pulse,
set the creep speed to 100 r/min or less.
CN3-4 This is used to output the data set in [Pr. PC09] to between MO1 and LG in terms of
voltage.
Resolution: 10 bits or equivalent
CN3-14 This signal output the data set in [Pr. PC10] to between MO2 and LG in terms of
voltage.
Resolution: 10 bits or equivalent
Connector
pin No.
CN3-5 Input 24 V DC (24 V DC ± 10% 300 mA) for I/O interface. The power supply capacity
changes depending on the number of I/O interface points to be used.
CN3-10
For sink interface, connect + of 24 V DC external power supply.
For source interface, connect - of 24 V DC external power supply.
CN3-3 Common terminal of input signal such as EM2 of the servo amplifier. This is separated
from LG.
For sink interface, connect - of 24 V DC external power supply.
For source interface, connect + of 24 V DC external power supply.
CN3-1 Common terminal of MO1 and MO2.
CN3-11 Pins are connected internally.
Plate Connect the external conductor of the shielded wire.
