Error Status Indicator
Error Status Retention
Motor Shaft Rotation
When the motor software detects a fault, LED will flash to indicate the fault code. Fault code below:
NOT USED
5V Low
IPM Over Current Fault
High DC Bus Voltage
Washer Communication
Timeout
DC Bus Transient
Micro Watchdog Timeout
Locked Rotor/Stalled Rotor
Error
Speed Sensor Error
Has LED Indicator
No Error status is only available until the motor power is
cycle.
Bi-direction, CW or CCW: looking at the Pulley End
1
There is no single flash error since it is hard to distinguish from normal
operation.
2
The microprocessor has detected a low voltage condition on the 5V power
supply, but not on the DC Bus. This error clears when the 5V power is
restored.
3
The MCU detected an over current fault with the IPM. The MCU will shut
down when this condition is detected.
8
The MCU detected a high DC Bus voltage condition. The MCU will stop
decelerating during this condition, but will not shut down. This error clears
when the DC Bus voltage falls within in acceptable range.
9
The MCU lost communication with the machine control. The MCU will shut
down when this condition is detected. This error automatically clears when
communications are restored.
10
The MCU detected a transient condition on the DC bus. The transient could
be could be caused by dropouts or spikes on the line. When this error is
detected, the MCU will shed the load and coast for a predetermined amount
of time. After coasting, the MCU will "soft start" and try to achieve the
target speed again. This error automatically clears when the transient
condition is resolved.
11
The watchdog timer in the microcontroller has reset the software. This error
indicates that the software stopped running. The MCU will shut down when
this condition is detected.
12
The MCU has detected a locked or stalled rotor condition. The MCU will shut
down for 20 seconds then retry. If it does not resume, this process will
repeat continuously.
15
The MCU has detected a speed sensor error (hall). The MCU will shut down
for 20 seconds then retry. If it does not resume, this process will repeat 6
times and then shut down.
