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 after power on.

RD-SG are connected when the servo is switched on and the servo
amplifier is ready to operate.

In position
INP
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.

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.

Limiting speed
VLC
CN1B

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.

Limiting torque
TLC
CN1B

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.

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-SG are connected.
When there is no warning, WNG-SG are disconnected within 1
second after power-on.
