Understanding the Status LEDs
Understanding the Status LEDs
The Status LEDs provide the same functionality for the D-style and M-style (including IP-sealed)
SmartMotors.
LED Status on Power-up:
• With no program and the travel limit inputs are low:
LED 0 will be solid red indicating the motor is in a fault state due to travel limit fault.
LED 1 will be off.
• With no program and the travel limit inputs are high:
LED 0 will be solid red for 500 milliseconds and then begin flashing green.
LED 1 will be off.
• With a program that disables only travel limits and nothing else:
LED 0 will be solid red for 500 milliseconds and then begin flashing green.
LED 1 will be off.

LED 0: Drive Status Indicator
Off
No power
Solid green
Drive on
Flashing green
Drive off
Flashing red
Watchdog fault
Solid red
Major fault
Alt. red/green
In boot load; needs firmware
LED 1: Trajectory Status Indicator
Off
Not busy
Solid green
Drive on, trajectory in progress
LED 2: CAN Bus Network Fault (Red LED)
Off
No error
Single Flash
At least one error
exceeded limit
Double Flash
Heartbeat or guard error
Solid
Busy off state
LED 3: CAN Bus Network Status (Green LED)
Blinking
Pre-operational state
(during boot-up)
Solid
Normal operation
Single
Device is in stopped state
NOTE:
D-style motors with the CDS CAN connector option use LED 1 to indicate a CAN error. Because this LED also
indicates the trajectory status, it will alternate red/green colors if a CAN error occurs while a trajectory is in progress.
Condition
Bt = 0, CAN bus OK
Bt = 1, CAN bus OK
Indication
Trajectory LED = Off
Trajectory LED = Green
Bt refers to Busy Trajectory
status bit. When the motor is
actively pursuing a trajectory,
that bit will be set to 1.
Bt = 0, CAN bus fault
Bt = 1, CAN bus fault
Trajectory LED = Flashing red
Trajectory LED = Alternating red/green
