Trouble ALM CN1-9 ALM-VIN are disconnected when power is switched off or the protective
circuit is activated to shut off the base circuit. Without alarm, ALM-VIN are
connected within about 1s after power on.
DO-1
Ready RD CN1-11 RD-VIN are connected when the servo is switched on and the servo
amplifier is ready to operate.
DO-1
In position INP CN1-10 INP-VIN are connected when the number of droop pulses is in the preset
in-position range. The in-position range can be changed using parameter
No.5.
When the in-position range is increased, INP-VIN may be kept connected
during low-speed rotation.
DO-1
Speed reached SA SA turns off when servo on (SON) turns off or the servo motor speed has
not reached the preset speed with both forward rotation start (ST1) and
reverse rotation start (ST2) turned off. SA turns on when the servo motor
speed has nearly reached the preset speed. When the preset speed is
20r/min or less, SA always turns on.
DO-1
Zero speed ZSP CN1-12 ZSP-VIN are connected when the servo motor speed is zero speed
(50r/min) or less. Zero speed can be changed using parameter No.24.
DO-1
Electromagnetic
brake interlock
MBR (CN1-12) Set " 1 " in parameter No.1 to use this parameter. Note that ZSP will
be unusable.
In the servo-off or alarm status, MBR-VIN are disconnected.
When an alarm occurs, they are disconnected independently of the base
circuit status.
DO-1
Warning WNG To use this signal, assign the connector pin for output using parameter
No.49. The old signal before assignment will be unusable.
When warning has occurred, WNG-VIN are connected.
When there is no warning, WNG-VIN are disconnected within about 1s
after power-on.
