Parameter Description
LF.43 Level overspeed
Value range
0,000...18,000 m/s
LF.44 Deceleration check level
Value range
0,000...15,000 m/s
LF.45 Level „running open doors"
Value range
0,000...0,300 m/s
LF.46 Speed deviation mode
This parameter serves as control, whether the motor speed can follow the actual speed. Die monitoring is active
only in closed-loop operation with motor encoder. The tripping level is adjusted with LF.47 . If the function is assi-
gned to a digital output, a warning is given.
Value range
off
on
LF.47 Speed deviation level
Value range
0...30 %
LF.48 Speed deviation tripping time
Value range
0,000...10,000 s
LF.49 Motor + Inverter OH-function
This parameter activates the temperature monitoring of motor and inverter. Precondition for the motor monitoring
is the connection of a motor temperature sensor to the terminals T1/T2. When the heat sink of the inverter reaches
a temperature of 90°C, the error E.OH is triggered and the drive is stopped. If the function is assigned to a digital
output, a warning is given. At a temperature of 75°C the output is reset and the drive continues to run. The display
shows the warning message „OH".
Value range
off
on
Setting Description
auto The displayed value is 110 % of the maximum speed (LF.01).
Setting Description
auto The displayed value is 96 % of the rated speed LF.22).
Setting Description
0,250 m/s Defines the maximum approach speed, on falling below this speed the doors
can open.
Setting Description
x No error switch off. The output condition. The output condition „speed devia-
taion warning" is set.
Inverter switches off the modulation with error E.hSd (high speed difference).
The output condition „speed deviataion warning" is set.
Setting Description
10 % The value in percent refers to the selected speed. The detection takes place
at constant run.
Setting Description
3,000 s Adjustment of the time between detection of a speed deviation and tripping of
the error E.hSd (LF.46 = 1).
Setting Description
x No error switch-off at overtemperature. The output condition „motor or inverter
excess temperature" is set.
When the heat sink of the inverter reaches a temperature of 90°C, the error
E.OH is triggered and the drive is stopped. At a temperature of 75°C the error
is reset and the drive continues to run. The display shows the warning mes-
sage „OH".
At an excess temperature of the motor the drive behaves according to LF.50.
The output condition „motor or inverter excess temperature" is set immedia-
tely.
