DESCRIPTION
1356 /1356P in corrupted state.
Encryption failure.
Flash did not properly write or
Checksum did not match.
Battery over limit.
Limit = (Nominal Voltage * 1.25) + 5V.
Battery under limit.
Limit = (Nominal Voltage * 0.7)
- 5V when Nominal Voltage ≥24V.
Limit = (Nominal Voltage * 0.7)
- 0.6V when Nominal Voltage =12V.
Driver 1 is in overcurrent (>3.5 amps).
Driver 2 is in overcurrent (>1.5 amps).
Driver 1 output pin is low when driver
is Off. This implies the pin has been
left open.
Driver 2 output pin is low when driver driver not functional.
is Off. This implies the pin has been
left open
PDO from master has not been
received within the time-out period.
Too many CAN bus errors detected.
Encoder wire open.
The EEPROM did not properly write.
Analog input exceeds 15.5V (voltage
input) or 7.5kΩ (resistance input).
External load impedance on
+5V Supply is too low.
External load impedance on
+12V Supply is too low.
External load on +5V and +12V
exceeds 200 mA.
