IONI LED indicators

IONI has two on-board led indicators which have dedicated indicating tasks:

• LED1 Motor control state indicator (green)
• LED2 Fault indicator (orange)

How to read indications

• LED1 and LED2 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.
• LED1 and LED2 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.
• LED2 and shows the first fault occurred if multiple fault states are active simultaneously.
• LED1 and LED2 are flashing together if device is in a firmware upgrade mode (DFU).

List of all LED1 and LED2 sequences

To see animated images, view this Wiki page in a web browser with animations enabled. The animations show Argon front panel, but the blinking sequences of IONI are equivalent when LED1=LD4 and LED2=LD3.

Faults

Only LED2 is being controlled by these faults, except in DFU mode when both leds blink together.

Fault reason	LED sequence	LED sequence as text
Hardware		LLSS
Progral or memory		LSLL
Internal comm error (CRC)		LSL
Initialization		LSS
Over current		SLL
Over temperature		LSLS
Over voltage		SLS
Following error		LS
Under voltage		SL
Motion blocked or motor runaway		SSL
Setpoint range exceeded		LSSL
SimpleMotion communication error		LSSS
Other/unknown, possibly configuration error such as motor mode Motor typeMT not selected		SSSL

Motor control states

Only LED1 is being controlled by these states.

Status	LED sequence	LED sequence as text	Motor output powered
Permanent stop (need device reset)		LLS	No
Fault stop (observe LD3 for reason)		Off	Depends on fault
Follow error recovery motion		LS	Yes
Initializing		SL	Yes
Homing		LSS	Yes
Run		On	yes
Drive disabled (enable signal/command missing) OR other/uncategorized (not any of above). For clarity, connect with Granity and see status bits.		LLSS	Yes or No

IONICUBE LED indicators

IONICUBE has four LED indicators that will are dedicated to:

LED1

Power on (24V supplied)

LED2

GPO1_X (LED on when GPO1_X is high)

LED3

Fault stop state (LED on when any of drives has fault stop state on)

LED4

Regenerative resistor is being driven
