3 SIGNALS AND WIRING
3.5 Signal (device) explanation
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 (or in 3.5 s to 4.0 s for a multi-axis drive unit).
For details, refer to "Alarm function" in the following manual.
MR-J5 User's Manual (Function)
■
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.
For details, refer to "In-position range setting" in the following manual.

■
RD (Ready)
When the drive unit 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 (mm/s)
When the set speed is 20 r/min (mm/s) 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 will turn off in 2.5 s to 3.5 s after power-on (or in 3.5
s to 4.0 s for a multi-axis drive unit).
■
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 (or in 3.5 s to 4.0 s for a multi-axis drive unit).
In an absolute position detection system with a battery-less ABS encoder, BWNG is always off.
■
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 (or in 3.5 s to 4.0 s for a multi-axis drive unit).
■
CDPS (Variable gain enabled)
When the gain of "Gain switching" is enabled, CDPS is on.
■
CDPS2 (Variable gain enabled 2)
If the gain of "Gain switching 2" is enabled, CDPS2 will turn on.
