3. SIGNALS AND WIRING
3 - 21
Device Symbol Function and application
Limiting torque TLC 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.
Warning WNG When a 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.
Battery warning BWNG 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.
Variable gain
selection
CDPS CDPS will turn on during variable gain.
Absolute position
undetermined
ABSV ABSV turns on when the absolute position is undetermined.
The device cannot be used in the speed control mode and torque control mode.
During tough drive MTTR When a tough drive is "Enabled" in [Pr. PA20], activating the instantaneous power failure tough
drive will turn on MTTR.

DICOM CN3-5
CN3-10
Input 24 V DC (24 V DC ± 10% 300 mA) (Note) for I/O interface. The power supply
capacity changes depending on the number of I/O interface points to be used.
For sink interface, connect + of 24 V DC external power supply.
For source interface, connect - of 24 V DC external power supply.
Digital I/F common DOCOM CN3-3 Common terminal of input signal such as EM2 of the servo amplifier. This terminal 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.
Shield SD Plate Connect the external conductor of the shielded wire.
Note. For the servo amplifiers manufactured in April 2016 or earlier (or manufactured in China in May 2016 or earlier), the value 100 mA
is applicable.
