Argon user guide/LED indicators
Argon has four front panel led indicators which have dedicated indicating tasks:
- LD1 SimpleMotion transmit led. Blinks when drive transmits data to bus.
- LD2 SimpleMotion receive led. Blinks when drive receives data from bus.
- LD3 Fault indicator
- LD4 Motor control state indicator

How to read indications
- LD1 and LD2, blink very briefly during data transmission. Due to short light pulses, these lights appear dimmer than other leds.
- LD3 and LD4 have programmed blinking sequences. Sequences consists series of short (S) and long (L) light pulses. For example LLS means the led will blink two long flashs and then one short flash. After sequence there will be a pause before the sequence repeats.
- LD3 and LD4 are independent and can show fault and motor state simultaneously. To easier reading sequence, cover one led with a thumb to be able to concentrate to one led.
- LD3 and shows the first fault occurred if multiple fault states are active simultaneously.
