CN1-48 ALM turns off when power is switched off or the protective circuit is
activated to shut off the base circuit. Without alarm occurring, ALM
turns on within 1.5s after power-on.
When using the signal, make it usable by the setting of parameter
No.PD13 to PD18.
DB turns off simultaneously when the dynamic brake is operated.
When using the external dynamic brake on the servo amplifier of 11
kW or more, this device is required. (Refer to section 12.6)
For the servo amplifier of 7kw or less, it is not necessary to use this
device.
CN1-49 RD turns on when the servo is switched on and the servo amplifier is
ready to operate.
CN1-24 INP 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, may be kept connected
during low-speed rotation.
INP turns on when servo on turns on.
SA turns off when servo on (SON) turns off or the servomotor 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 servomotor speed has nearly reached the preset speed. When
the preset speed is 20r/min or less, SA always turns on.
CN1-25 VLC turns on when speed reaches the value limited using any of the
internal speed limits 1 to 7 (parameter No. PC05 to PC11) or the
analog speed limit (VLA) in the torque control mode. VLC turns off
when servo on (SON) turns off.
TLC turns on when the torque generated reaches the value set to the
Forward torque limit (parameter No. PA11), Reverse torque limit
(parameter No. PA12) or analog torque limit (TLA).
