A-axis malfunction
ALM-A
CN3-11
DO-1
B-axis malfunction
ALM-B
CN3-24
ALM-A/ALM-B turns off when power is switched off or the protective circuit is
activated to shut off the base circuit.
Without alarm occurring, ALM-A/ALM-B turns on within about 1.5s after
power-on.
A-axis
electromagnetic
brake interlock
MBR-A
CN3-12
When using this signal, set operation delay time of the electromagnetic brake
in parameter No.PC02.
In the servo-off or alarm status, MBR-A/MBR-B turns off.
DO-1
B-axis
electromagnetic
brake interlock
MBR-B CN3-25
A-axis in-position
INP-A
DO-1
B-axis in-position
INP-B
When using the signal, make it usable by the setting of parameter No.PD07
or PD09.
INP-A/INP-B 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-A/INP-B 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 and the torque loop
mode.
A-axis ready
RD-A
DO-1
B-axis ready
RD-B
When using the signal, make it usable by the setting of parameter No.PD07
or PD09.
RD-A/RD-B turns on when the servo is switched on and the servo amplifier is
ready to operate.
A-axis speed
reached
SA-A
DO-1
B-axis speed
reached
SA-B
When using this signal, make it usable by the setting of parameter No.PD07
or PD09.
When the servo is off, SA will be turned OFF. When servo motor rotation
speed becomes approximately setting speed, SA-A/SA-B will be turned ON.
When the preset speed is 20r/min or less, SA-A/SA-B always turns on. This
signal cannot be used in the position loop mode and the torque loop mode.
A-axis limiting
speed
VLC-A
DO-1
B-axis limiting
speed
VLC-B
When using this signal, make it usable by the setting of parameter No.PD07
or PD09.
VLC-A/VLC-B turns on when the servo motor speed reaches the speed set
with the controller in the torque loop mode. VLC-A/VLC-B turns off when the
servo turns off.
This signal cannot be used in position loop mode and the torque loop mode.
A-axis limiting
torque
TLC-A
DO-1
B-axis limiting
torque
TLC-B
When using this signal, make it usable by the setting of parameter No.PD07
or PD09.
When torque is produced level of torque set with controller, TLC-A/TLC-B will
be turned ON. When the servo is off, TLC-A/TLC-B will be turned OFF.
This signal cannot be used in the torque loop mode.
