Set the following:
– (A) Delay time actual value sensing:
In most cases you do not have to change this value. If you switch on the motor with the
safety functions active (SLS, SDI or SSM) and the inverter responds when switching on
with a safety fault, increase this value in the range 50 % … 100 % of the motor excitation
build-up time (p0346).
– (B) Minimum current actual value sensing:
In most cases you do not have to change this setting. If the inverter responds with a
fault when the current drawn by the motor is low, then reduce these values in 1 %
increments until the fault no longer occurs.
– (C) Voltage tolerance acceleration:
In most cases you do not have to change this parameter. During acceleration with very
short ramp-up and ramp-down times, if the inverter responds with a safety function fault,
increase this value step-by-step by approx. 10%.
– (D) Fault tolerance:
In most cases you do not have to change this parameter. This parameter can suppress
sporadic faults of the safety functions. The parameter defines how often the inverter
tolerates its internal plausibility monitoring per second.
6. Close the screen forms.
You have set the encoderless actual value sensing.
