ru - Parameter
21
Display Value Significance
rcon 69 Reverse Constant: drive runs with constant speed in reverse
LS 70 Low Speed: Control release is activated, no direction of rotation is
preset, modulation is switched off, output voltage = 0, drive is not
guided
SLL 71 Stall function is active
LAS 72 LA - Stop is active (acceleration ramp stopped)
LdS 73 LD - Stop is active (deceleration ramp stopped)
SSF 74 Speed - Search - function is active
dcb 75 DC - braking is active
bbl 76 Base - Block time runs out, d.c. to a.c. switched off
dLS 77 Low Speed according to DC - braking
In ru. 3 the actual output frequency of the inverter with a resolution of 0.1 Hz is shown.
A reverse rotating field at the output (Reverse) is represented by a display of negative
frequencies.
Examples: Display: 18.1 => Output frequency 18.1 Hz, forward
Display: -18.1 => Output frequency 18.1 Hz, reverse
Attention: The display of ru.3 and ru.6 have a resolution of 0,0125 Hz via bus.
ru. 6 shows the actual set frequency. The resolution and the display of different
directions of rotation correspond to ru. 3. If no direction of rotation is selected, then the
set value is displayed which would result from a forward direction of rotation. It is
possible to check the given set value before the direction of rotation is enabled.
Parameter ru. 7 specifies the actual utilization of the inverter in %. 100% means the
output current is equal to the rated current of the inverter. Only positive values are
displayed, i.e. you cannot determine whether the drive is motor-driven or in
regenerative operation.
