Function/Application
Used for connection with the controller or preceding-axis servo amplifier.
Used for connection with the next-axis servo amplifier or for connection of the
cap.
Used for connection with the servo motor encoder.
When using as absolute position detection system, connect to battery (MR-
J3BAT).
For setting battery, make sure that charge lamp is off more than 15 minutes
after main circuit power is switched off.
between P-N terminals in the tester or the like. Replace the battery with main
circuit power OFF and with control circuit power ON. Replacing the battery with
the control circuit power OFF results in loosing absolute position data.
The personal computer is connected.
Function/Application
Turn EM1 off (open between commons) to bring the motor to an
forced stop state, in which the base circuit is shut off and the
dynamic brake is operated.
Turn EM1 on (short between commons) in the forced stop state
to reset that state.
When parameter No.PA.04 is set to "
(always ON) can be set inside.
Devices can be assigned for DI1 DI2 DI3 with controller setting.
For devices that can be assigned, refer to the controller
instruction manual. The following devices can be assigned for
Q172HCPU Q173HCPU QD75MH.
DI1: upper stroke limit (FLS)
DI2: lower stroke limit (RLS)
DI3: near-point dog (DOG)
Function/Application
ALM turns off when power is switched off or the protective circuit
is activated to shut off the base circuit.
Without alarm occurring, ALM turns on within about 1.5s after
power-on.
When using this signal, set operation delay time of the
electromagnetic brake in parameter No.PC02.
In the servo-off or alarm status, MBR turns off.
INP turns on when the number of droop pulses is in the preset
in-position range. The in-position range can be changed using
parameter No. PA10.
When the in-position range is increased, INP may be on
conductive status during low-speed rotation.
INP turns on when servo on turns on.
This signal cannot be used in the speed loop mode.
When using the signal, make it usable by the setting of
parameter No.PD07 to PD09.
RD turns on when the servo is switched on and the servo
amplifier is ready to operate.
