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 servo amplifier).
■
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 (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.
For the MR-J5-_A_ servo amplifier, SA does not turn ON even when the servo motor speed reaches the set speed by external
force when both ST1 (forward rotation start) and ST2 (reverse rotation start) are off.
