3.5 Signal (device) explanations
Symbol Function and application
WNG When warning has occurred, WNG turns on. When a warning is not occurring, turning on the power will turn off
WNG after 2.5 s to 3.5 s.
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, turning on the power will turn off BWNG after 2.5 s to 3.5 s.
CDPS CDPS will turn on during variable gain.
ABSV ABSV turns on when the absolute position is undetermined.
The device cannot be used in the velocity mode and torque mode.
MTTR When a tough drive is enabled in [Pr. PA20], activating the instantaneous power failure tough drive will turn on
MTTR.
CLDS CLDS turns on during fully closed loop control.
This is used with servo amplifiers with software version A1 or later.
Symbol Connector Function and application
pin No.
LA CN3-6 These devices output pulses of encoder output set in [Pr. PA15] and [Pr. PA16] in the differential line
LAR CN3-16 driver type.
In CCW rotation of the servo motor, the encoder B-phase pulse lags the encoder A-phase pulse by a
phase angle of /2.
LB CN3-7
The relation between rotation direction and phase difference of the A-phase and B-phase pulses can
LBR CN3-17
be changed with [Pr. PC03].
Output pulse specification, dividing ratio setting, and electronic gear setting can be selected.
LZ CN3-8 The encoder zero-point signal is output in the differential line driver type. One pulse is output per servo
LZR CN3-18 motor revolution. This turns on when the zero-point position is reached. (negative logic)
The minimum pulse width is about 400 s. For home position return using this pulse, set the creep
speed to 100 r/min or less.
MO1 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
MO2 CN3-14 This signal outputs the data set in [Pr. PC10] to between MO2 and LG in terms of voltage.
Resolution: 10 bits or equivalent
Symbol Connector Function and application
pin No.
Input 24 V DC (24 V DC  10% 300 mA) for I/O interface. The power supply capacity changes
DICOM CN3-5
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.
DOCOM 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.
LG CN3-11 Common terminal of MO1 and MO2.
SD Plate Connect the external conductor of the shielded wire.
