8 Diagnostics
8.1 Diagnostic LED’s
The SimpleServo has five diagnostic LEDs mounted on the front panel and two LEDs located
on the bottom side near RS485 connector. These LEDs are designed to help you monitor
system status and activity as well as troubleshoot any faults.
8.1.1 Front panel LEDs
READY (Green)
Green LED lights when drive is enabled and there is no fault. If drive is disabled by the
ENABLE input, or because any fault occurs, this light will turn off.
Fault (Red)
Red LED lights when drive detects fault. The LED will flash once or multiple times according to
Table 15 below, than pause for about 1.5 Sec then start over again until fault is reset.
Note
SSi drives have more then 9 faults. If the fault LED turns on permanently then the fault
code is higher then 9. In this case you need to use MotionView to retrieve the fault code.
Refer to Programmer’s manual for details on fault codes for SSi drives.
OVER-CURRENT (O/C)
Red LED lights when drive’s current limiting is active.
OVER-VOLTAGE (O/V) (Red)
Red LED lights when the drive bus exceeds threshold limit caused by motor regeneration
energy flowing back into the drive. If this LED lights frequently, you will need to connect a
dumping resistor.
POWER (Green)
Green LED lights when power is applied to the drive.
8.1.2 Bottom side LEDs
Green LED
This LED lights up when drive receive data over any interface (RS232/485 or Ethernet).
Red LED
This LED shows state of the user program.
Steady ON
no valid user program in the drive’s memory
Blinking user program is running
Off program in memory and valid but not running
