Output device explanation
■ALM (Malfunction)
If the protective circuit operates and shuts off the base circuit, ALM will turn off.
If an alarm is not occurring, ALM will turn on in 2.5 s to 3.5 s after power-on.
■INP (In-position)
If droop pulses are within the in-position range, INP will turn on. The in-position range can be changed with [Pr. PA10]. When
the servo motor is operated at low speed by increasing the in-position range, INP may remain on.
The device cannot be used in the velocity mode or torque mode.
■RD (Ready)
When the servo amplifier is switched to the servo-on state, RD switches on.
■SA (Speed reached)
At servo-off, SA is off. When the servo motor speed reaches the following range, SA turns on.
Set speed ± ((Set speed × 0.05) + 20) r/min
When the set speed is 20 r/min or less, SA is always on.
The device cannot be used in the position mode and torque mode.
■WNG (Warning)
WNG turns on when a warning occurs. If a warning is not occurring, WNG turns off in 2.5 s to 3.5 s after power-on.
■BWNG (Battery warning)
If [AL. 092 Battery cable disconnection warning] or [AL. 09F Battery warning] occurs, BWNG will turn on. If a battery warning
is not occurring, BWNG will turn off in 2.5 s to 3.5 s after power-on.
The absolute position detection system will be supported in the near future.
■WNGSTOP (Motor stop warning)
WNGSTOP will turn on if a warning that the motor cannot be driven occurs. If a motor stop warning is not occurring,
WNGSTOP will turn off in 2.5 s to 3.5 s after power-on.
■CDPS (Variable gain selection)
When the gain of "Gain switching" is enabled, CDPS is on.
■CDPS2 (Variable gain selection 2)
If the gain of "Gain switching 2" is enabled, CDPS2 will turn on.
■ABSV (Absolute position undetermined)
ABSV turns on when the absolute position is undetermined.
The absolute position detection system will be supported in the near future.
■MTTR (During tough drive)
When a tough drive is set to "Enabled" in [Pr. PA20], activating the instantaneous power failure tough drive turns on MTTR.
■MBR (Electromagnetic brake interlock)
MBR is off in the servo-off state or at an alarm occurrence.
If using the device, set an operation delay time of the electromagnetic brake in [Pr. PC02].
