#
Speed error VSD
Required speed has not been reached
Bit 0 Valency 1
Lower control range limitation
Speed has not been reached because control range limitation has
become
active
for measures, refer to error code 80
Bit 1 Valency 2...3
Upper control range limitation
Speed has not been reached because control range limitation has
become
active
for measures, refer to error code 80
Bit 2 Valency 4...7
Interrupt shutdown due to electromagnetic interference
Speed has not been reached due to too much electromagnetic int
erference on
the sensor line
for measures, refer to error code 81
Bit 3 Valency ≥ 8
Curve too steep in terms of ramp speed
Check speed differential between the curvepoints and the modulat
ing operating
ramp setting (parameter 544). 1.
Modulating operating ramp 32 seconds Curve slope max. 10% for LMV37.4 ramp of 20 seconds (20% for 10 seconds or 40% for 5 seconds)
2.
Modulating operating ramp 48 seconds Curve slope max. 10% for LMV37.4 ramp of 30 seconds (20% for 15 seconds or 30% for 10 seconds)
3. Modulating operating ramp 64 seconds Curve slope max. 10% for LMV37.4 ramp of 40 seconds (20% for 20 seconds or 40% for 10 seconds)
Between the ignition point (P0) and the low-fire point (P1), the speed
change in modulating mode may be a maximum of 40%, independent of the LMV3… ramp. 2.
The setting of the VSD ramp must be about 20% faster than the ramps in the basic unit (parameters 522, 523).
Bit 4 Valency ≥ 16
Interruption of speed signal
No speed detected in spite of control. 1.
Check if the motor turns.
2.
Check if the speed sensor delivers a signal (LED / check distance
from the
sensor disk).
3. Check wiring of the VSD.
Bit 5 Valency ≥ 32
Quick shutdown due to excessive speed deviation
Speed deviation was for about 1 s >10% outside the anticipated
range.
1. Check ramp times of the LMV37.4... and VSD. 2. Check wiring of the VSD.
