When warning has occurred, WNG turns on. Without warning occurring, WNG turns off about 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 about 2.5 s to 3.5 s after
power-on.
CDPS will turn on during variable gain.
ABSV turns on when the absolute position erased.
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.
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 /2.
The relationships between rotation direction and phase difference of the A-phase and B-
CN3-7
phase pulses can be changed using [Pr. PC03].
CN3-17
Output pulse specification, dividing ratio setting, and electronic gear setting can be
selected.
CN3-8 Outputs the zero-point signal in the differential line driver type of the encoder. One pulse
is output per servo motor revolution. Turns on when the zero-point position is reached.
CN3-18
(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.
CN3-4 Used to output the data set in [Pr. PC09] to across MO1-LG in terms of voltage.
Resolution: 10 bits or equivalent
CN3-14 This signal output the data set in [Pr. PC09] 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% 200 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 for input device such as EM2 of the servo amplifier. DOCOM 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.
