Error (RD)
Excess current or inadmissible rotor position sensor condition
n2 (YE)
Fixed speed n2 was selected
SET-ACTUAL (YE)
The difference between set to actual speed is smaller than 20% of
the currently specified set value speed. In the lower speed range (<
0,25 n-max.) this threshold increases.
The monitoring function is time-delayed.
With deviation 1% above/below threshold approx. 10 sec.
With deviation 100% above/below threshold approx. 0,5 sec.
Stand-by (GN)
ON = Control device ready for operation
OFF= Control device collective failure
- Intermediate circuit voltage > 420 V
- Intermediate circuit voltage < 95 V
- Heat sink temperature > 80°C
If there is a failure the power amplifier is immediately cut-off. The
failure remains filed until it is acknowledged. The acknowledgement
of the failure signal is conducted by removing the regulator release.
M2 (GN)
Input thermal circuit breaker motor is on High-Potential.
