Alarm
SELFCHECK #1
after a while turns to:
CHECK #1 OK:
occurs when the system passes the SELFCHECK #1. To pass
SELFCHECK #1 following conditions must be matched (AND logic):
Current from V to W to 14 or 15
AND
Current from W to V to -14 or -15
AND
Current from W to U to 14 or 15
AND
Current from U to W to -14 or -15
AND
Motor Resistance V to W in the window 180 to 380
AND
Motor Resistance W to U in the window 180 to 380
SELCK 1.1 VBATT:
occurs in case the rail voltage (battery voltage) is lower than
29V (for 48V battery) and 19V (for 24V battery). It reports a failure on the cable
between plus or minus battery and the controller.
SELCK 1.2 MOT VW:
occurs in case the linked voltages between terminal V and
W (Vvw and Vwv) to get the expected current (14.7Adc) are both higher than
10Vdc. It reports a failure with terminal W or terminal V of the motor (interrupted).
SELCK 1.3 MOT WU:
occurs in case the linked voltages between terminal W and
U (Vwu and Vuw) to get the expected current (14.7Adc) are both higher than
10Vdc It reports a failure with terminal U or terminal W of the motor (interrupted).
SELCK 1.4 CTL VW:
occurs in case only one between the linked voltages at
terminals V and W (Vvw or Vwv) to get the expected current (14.7Adc) is higher
than 10Vdc. It reports a failure in a power mosfet in the half bridges of terminals V
or W.
SELCK 1.5 CTL WU:
occurs in case only one between the linked voltages at
terminals W and U (Vwu or Vuw) to get the expected current (14.7Adc) is higher
than 10Vdc. It reports a failure in a power mosfet in the half bridges of terminals W
or U.
SELCK 1.6 CTL KO:
occurs in case none of the above failures has been detected
but at least one between the injected currents (Ivw, Iwv, Iwu, Iuw) is lower than
10Adc (when 14.7Adc are expected instead). It reports a generic failure in the
controller (power or logic).
SELCK 1.7 STA #1:
occurs in case none of the above conditions has been
detected. So reading and deepen analysis of STATUS#1 information is needed for
deciding the proceeding.
