CN1B
ALM-SG are disconnected when power is switched off or the
18
protective circuit is activated to shut off the base circuit. Without
alarm, ALM-SG are connected within 1 after power on.
CN1A
RD-SG are connected when the servo is switched on and the servo
19
amplifier is ready to operate.
CN1A
INP-SG are connected when the number of droop pulses is in the
18
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.
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.
CN1B
VLC-SG are connected when speed reaches the value set to any of
6
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.
CN1B
TLC-SG are connected when the torque generated reaches the
6
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.
CN1B
ZSP-SG are connected when the servo motor speed is zero speed
19
(50r/min) or less. Zero speed can be changed using parameter No.
24.
CN1B
Set
1
in parameter No. 1 to use this parameter. Note that
19
ZSP will be unusable.
In the servo-off or alarm status, MBR-SG are disconnected.
When an alarm occurs, they are disconnected independently of
the base circuit status.
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-SG are connected.
When there is no warning, WNG-SG are disconnected within 1
second after power-on.
