DO–1
Set
1 in parameter No. 1 to use this
parameter. Note that ZSP will be made
unavailable.
NOTICE
In the servo-off or alarm status, MBR-SG are disconnected.
When an alarm occurs, they are disconnected at zero speed
or less, independently of the base circuit status.
Speed reached SA CN1A
18
SA-SG are connected when the servo motor speed has
nearly reached the preset speed. When the preset speed is
50r/min or less, SA-SG are kept connected.
DO–1
Limiting speed VLC CN1B
6
DO–1
Zero speed ZSP CN1B
19
ZSP-SG 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
Limiting torque TLC CN1B
6
TLC-SG are connected when the torque generated reaches
the value set to the internal torque limit 1 (parameter No. 28)
or analog torque limit (TLA). They are disconnected when the
servo-on signal (SON) switches off.
DO–1
Warning WNG DO–1
Set
1 in parameter No. 49 to use
this signal.
NOTICE
When warning has occurred, WNG-SG are connected.
When there is no warning, WNG-SG are disconnected within
1 second after power-on.
Trouble ALM CN1B
18
ALM-SG are disconnected when power is switched off or the
protective circuit is activated to shut off the base circuit.
Without alarm, ALM-SG are connected within 1 second after
power on. Connect the regenerative brake option or the like
with a temperature detector to make up a protective circuit.
DO–1
Ready RD CN1A
19
RD-SG are connected when the servo is switched on and
the servo amplifier is ready to operate.
DO–1
In position INP CN1A
18
INP-SG 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-SG may be
kept connected during low-speed rotation.
DO–1
Note: 1. Refer to Section 3-1-4.
2. P: Position control mode, S: Speed control mode, T: Torque control mode
VLC-SG are connected when speed reaches the value set
to any of the internal speed limits 1 to 3 (parameters No. 8
to 10) or the analog speed limit (VLA) in the torque control
mode. They are disconnected when the servo-on signal
(SON) switches off.
