11.1.6 Six blinks alarms
1)
STBY I HIGH
Cause:
It occurs if the rest state current signals (measured on the phases U
and W) are not in the window 2.5±0.3Vdc after switching on the key
and 2.5±0.15Vdc when in the steady state. These voltage are
measured between D46 and D45 anodes and gnd.
Remedy:
The 2.5Vdc rest state values should be TM3 (for D46) and TM2 (for
D45) factory adjusted. If the problem is not due to TM3 or TM2
settings, to try a logic substitution.
2)
VMN NOT OK
Cause:
It occurs when in the initial rest state at least one of the phases of
the motor voltage is high: that means the voltage between D47 and
D48 anodes and gnd are not in the window 2.5±0.3Vdc (see Fig.
11.1.6.2).
Remedy:
If the alarm occurs permanently, it is necessary to substitute the
logic.
3)
LOGIC FAILURE #3
Cause:
It occurs when in the rest state the Vv-Vu phase motor voltage is
high: that means the voltage between D47 anode and gnd is not in
the window (Vv-Vu)0±0.25Vdc (see Fig. 11.1.6.2).
Remedy:
If the alarm occurs permanently, it is necessary to substitute the
logic.
