extended by selection of either of the S-ramps:
1 = Accel./decel. time extended by 10%
approx.
2 = Accel./decel. time extended by 20%
approx.
The inverter holds the trip codes of the last four
trips in memory. These are accessed as shown
in the diagram above. When a new trip occurs,
the previous last (fourth) trip is deleted.
For trip codes refer to page 44.
Starting frequency can be set at any value
from 0 up to 15Hz in steps of 1Hz.
NOTE Function 30 = 0 gives 0.2Hz.
Factory-set default is 1.
Torque limitation is set as a percentage of rated
torque computed from Functions 70, 71 and 72.
Setting ranges
0 = No limit (except overcurrent protection)
20 = 20% increasing in steps of 1% to…
180 = 180%
The purpose of this Function is to prevent over-
loading of the braking circuit. Set as follows:
0 = When an external braking circuit is not
used or is not available.
1 = Set to this value when installing an exter-
nal braking circuit.
NOTE External braking is not available with
the VXS20-1 inverter.

WARNING Accel./decel. times and
speed settings may be altered by
inappropriate settings of the torque

commissioned with care if torque
