APPENDIX B
Table B-5-2c Indicators of RSI-PPVC-AXRY-ENPG-PG3
Indicator
State
Indication
D1/D2/D3
Encoder
input signal
indicator
ON or flash: The encoder has signal input.
OFF: The encoder does not have signal input.
D6 Power
supply
indicator
ON: Normal.
OFF: Power is not connected.
LED1 Encoder
input signal
quality
indicator
OFF: Input signal is normal, speed is stable and there is no interference.
ON: Input signal is slightly instable, which occurs when motor accelerates/
decelerates or encoder signal input suffers slight interference.
Flash slowly: Input signal is moderately instable, which occurs when motor
accelerates/decelerates or encoder signal input suffers moderate interference.
Flash quickly: Input signal is seriously instable, which occurs when motor
accelerates/decelerates quickly or encoder signal input suffers severe
interference.
LED2 Signal
processing
quality
indicator of
PG card
OFF: Signal processing is normal, speed is stable and there is no interference.
ON: Signal is slightly instable, which occurs when motor accelerates/
decelerates or interference during signal input is not completely filtered (The
number of interference pulses that are not filtered is less than 10 per time unit).
Flash slowly: Signal is moderately instable, which occurs when motor
accelerates/decelerates or interference during signal input is not completely
filtered (The number of interference pulses that are not filtered is less than
30 per time unit).
Flash quickly: Signal is seriously instable, which occurs when motor
accelerates/decelerates or interference during signal input is not completely
filtered (The number of interference pulses that are not filtered is more than
30 per time unit).
LED3 Inter-
lock state
indicator
OFF: Inter-lock disabled.
ON: Inter-lock enabled.
LED4 System
state indicator
OFF: The system is not operating or abnormal.
Flash: The encoder cable breaks.
ON: Normal.
