Malfunction
ALM
CN1-48 When an alarm occurs, ALM will turn off.
When an alarm does not occur, ALM will turn on after 2.5 s to 3.5 s after
power-on.
When [Pr. PD34] is "_ _ 1 _", an alarming or warning will turn off ALM.
DO-1
Dynamic
brake interlock
DB
When using the signal, enable it by setting [Pr. PD23] to [Pr. PD26], [Pr.
PD28], and [Pr. PD47]. DB turns off when the dynamic brake needs to
operate. When using the external dynamic brake on the servo amplifier of
11 kW or more, this device is required. (Refer to section 11.17.)
For the servo amplifier of 7 kW or less, it is not necessary to use this
device.
The external dynamic brake cannot be used with 11 kW or more servo
amplifier for compliance with SEMI-F47 standard. Do not assign DB
(Dynamic brake interlock) in [Pr. PD23] to [Pr. PD26], [Pr. PD28], and [Pr.
PD47]. Failure to do so will cause the servo amplifier to become servo-off
when an instantaneous power failure occurs.
DO-1
Ready
RD
CN1-49 Enabling servo-on to make the servo amplifier ready to operate will turn on
RD.
DO-1
In-position INP
CN1-22
CN1-24
When the number of droop pulses is in the preset in-position range, INP
will turn on. The in-position range can be changed using [Pr. PA10]. When
the in-position range is increased, INP may be on during low-speed
rotation.
INP turns on when servo-on turns on.
DO-1
Speed reached
SA
When the servo motor speed reaches the following range, SA will turn on.
Set speed ± ((Set speed × 0.05) + 20) r/min
When the preset speed is 20 r/min or less, SA always turns on.
SA does not turn on even when the SON (Servo-on) is turned off or the
servo motor speed by the external force reaches the preset speed while
both ST1 (Forward rotation start) and ST2 (reverse rotation start) are off.
DO-1
Limiting speed
VLC
CN1-25 VLC turns on when speed reaches a value limited with any of [Pr. PC05
Internal speed limit 1] to [Pr. PC11 Internal speed limit 7] or VLA (Analog
speed limit).
This turns off when SON (Servo-on) turns off.
DO-1
Limiting torque
TLC
TLC turns on when a generated torque reaches a value set with any of [Pr.
PA11 Forward torque limit], [Pr. PA12 Reverse torque limit], or TLA
(Analog torque limit).
