448
Torque, speed feedback Gear ratio with
encoder
(TOR-SF GEARRATIO)
Value:
0.001 - 100.000
1.000
Function:
This parameter is only used if
Torque control, speed
feedback
[5] has been selected in parameter 100. If an
encoder has been fitted to the gearshaft, a gear ratio
must be set - otherwise the adjustable frequency drive
will not be able to calculate the output frequency cor-
rectly.
For a gear ratio of 1:10 (gearing down of motor rpm),
set the parameter value to 10.
If the encoder has been fitted directly on the motor
shaft, set the gear ratio to 1.00.
Description of choice:
Set the required value.
449
Torque, speed feedback Friction loss
(TOR-SF FRIC. LOSS)
Value:
0.00 - 50.00% of rated motor torque
0.00%
Function:
This parameter is only used if
Torque control, speed
feedback
[5] has been selected in parameter 100.
Set the friction loss as a fixed percentage loss of rated
torque. In motor operation, the friction loss will be add-
ed to the torque, while in generating operation it will be
deducted from the torque.
See section
Setting of parameters, torque regulation,
speed feedback
.
Description of choice:
Set the required value.
450
AC line voltage at AC line fault
(MAINS FAIL VOLT.)
Value:
180-240 V for 200-240 V units
180
342-500 V for 380-500 V units
342
473-600 V for 525-600 V units
495
473-690 V for 525-690 V units
495
Function:
Set the voltage level at which parameter 407 AC Line
fault is to be activated. The voltage level for activating
the AC line fault functions must be lower than the rated
AC line voltage supplied to the adjustable frequency
drive. As a rule of thumb, parameter 450 can be set to
10% below the rated AC line voltage.
Description of choice:
Set the level for activating AC line fault functions.
NOTE
If this value is set at too high a level, the
AC line fault function set in parameter 407
can be activated, even if the AC line volt-
age is present.
453
Speed closed loop gear ratio
(SPEED GEARRATIO)
Value:
0.01 - 100.00
1.00
Function:
This parameter is only used if
Speed control, closed
loop
[1] has been selected in parameter 100
Config-
uration.
If the feedback has been fitted to the gearshaft, a gear
ratio must be set - otherwise the adjustable frequency
drive will not be able to detect an encoder loss.
For a gear ratio of 1:10 (gearing down of motor rpm),
set the parameter value to 10.
If the encoder has been fitted directly on the motor
shaft, set the gear ratio to 1.00.
Please note, that this parameter only has influence on
the encoder loss function.
Description of choice:
Set the required value.
