2042 / 3
FrS
R/WS
Nominal motor frequency given on the rating plate
Unit: 0.1 Hz
Factory setting: if bFr = 50: 500 if bFr = 60: 600
Adjustment range: 100 to 5000
Note: The ratio
must not exceed the following values:
ER23-...K: 7 max.
ER23
-.../
3K: 7 max.
ER23

4K: 14 max.

6K: 17 max.

2042 / 4
nCr
R/WS
Nominal motor current given on the rating plate
Unit: 0.1 A
Factory setting: According to drive rating
Adjustment range: 0.25 to 1.5 In (1)
(1) In corresponds to the nominal drive current indicated in the Installation Manual and on the
drive rating plate.
9604
2042 / 5
nSP
R/WS
Nominal motor speed given on the rating plate
Unit: 1 rpm
Factory setting: According to drive rating
Adjustment range: 0 to 32767 RPM
0 to 9999 RPM then 10.00 to 32.76 KRPM
If, rather than the nominal speed, the rating plate indicates the synchronous speed and the slip
in Hz or as a %, calculate the nominal speed as follows:
Nominal speed = Synchronous speed x
or
Nominal speed = Synchronous speed x
(50 Hz motors)
or
Nominal speed = Synchronous speed x
(60 Hz motors)

2042 / 7
COS
R/WS
Motor Cos Phi given on the rating plate
Unit: 0.01
Factory setting: According to drive rating
Adjustment range: 50 to 100

2042 / 2C
rSC
R/WS
Cold state stator resistance
Factory setting: 0
0 = "nO": Function inactive. For applications which do not require high performance or do not
tolerate autotuning (passing a current through the motor) each time the drive is switched on.
1 = "InIt": Activates the function. To improve low-speed performance whatever the thermal state
of the motor.
>1 = "XXXX"
XXXX: Value of cold state stator resistance used, in m
Ω
.
Note:
It is strongly recommended that this function is activated for Lifting and Handling
applications.
The function should be activated (InIt) only when the motor is in cold state.
When rSC = InIt, parameter tUn is forced to POn. At the next run command or the next power-
up, the stator resistance is measured with an auto-tune. Parameter rSC then changes to this
value (XXXX) and maintains it; tUn remains forced to POn. Parameter rSC remains at InIt as
long as the measurement has not been performed.
Value XXXX can be forced or changed using the jog dial (1).
Procedure:
- Check that the motor is cold.
- Disconnect the cables from the motor terminals.
- Measure the resistance between 2 of the motor terminals (U. V. W) without modifying its
connection.
- Use the jog dial to enter half the measured value.
Increase the factory setting of UFr (page
) to 100% rather than 20%.
Note:
Do not use rSC on any other setting than nO or tUn = POn with the flying restart function (FLr
page
).
