Description
0
The value at reading is undefined.
1 S_ERF
EEP-ROM write completed
When a value is not written to EEP-ROM, S_ERF turns on. While a value is being written to EEP-ROM,
S_ERF turns off.
2 S_SA
Speed reached
When the servo motor speed reaches the following range, S_SA turns 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.
3 S_MBR
Electromagnetic brake interlock
When a servo-off status or alarm occurs, S_MBR will turn off.
4 S_CDPS
Variable gain selection
S_CDPS turns on during gain switching.
5
The value at reading is undefined.
6
7 S_TL
Analog torque limit selection
When TL (External torque limit selection) is turned on, S_TL turns on.
8 S_TL1
Torque limit selection
When C_TL1 or TL1 (Internal torque limit selection) is turned on, S_TL1 turns on.
9
The value at reading is undefined.
10
11
12 S_INP
In-position
When the number of droop pulses is in the in-position range, S_INP will turn on. The in-position range can
be changed with [Pr. PA10]. When the in-position range is increased, INP may be always on during low-
speed rotation.
13 S_TLC
Limiting torque
S_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).
14 S_ABSV
Absolute position undetermined
S_ABSV turns on when the absolute position is undetermined.
15 S_BWNG
Battery warning
When [AL. 92 Battery cable disconnection warning] or [AL. 9F Battery warning] has occurred, S_BWNG
turns on. When the battery warning is not occurring, S_BWNG will turn off in 2.5 s to 3.5 s after power-on.
