IONI LED indicators

From Granite Devices Knowledge Wiki
Jump to: navigation, search
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[edit | edit source]

  • 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[edit | edit source]

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[edit | edit source]

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

Motor control states[edit | edit source]

Only LED1 is being controlled by these states.

Status LED sequence LED sequence as text Motor output powered
Permanent stop (need device reset) 4LLS.gif LLS No
Fault stop (observe LD3 for reason) 4OFF.gif Off Depends on fault
Follow error recovery motion 4LS.gif LS Yes
Initializing 4SL.gif SL Yes
Homing 4LSS.gif LSS Yes
Run 4ON.gif On yes
Drive disabled (enable signal/command missing) OR other/uncategorized (not any of above). For clarity, connect with Granity and see status bits. 4LLSS.gif LLSS Yes or No

IONICUBE LED indicators[edit | edit source]

IONICUBE has four LED indicators that will are dedicated to:

Power on (24V supplied)
GPO1_X (LED on when GPO1_X is high)
Fault stop state (LED on when any of drives has fault stop state on)
Regenerative resistor is being driven
