05.59 : Rotation direction
Adjustment range : Clockwise (0) or C/clockwise (1)
Factory setting : Clockwise (0)
Format: 8 bits
This parameter is used to modify the direction of rotation when
viewed from the drive end, without changing the speed
reference sign.
It is only taken into account when the drive is stopped.
05.60 : Low-speed switching frequency
Adjustment range : 2 kHz (0) to 18 kHz (19)
Factory setting : 3 kHz (2) for the POWERDRIVE MD2
4 kHz (4) for the POWERDRIVE FX
Format: 8 bits
05.60 Frequency 05.60 Frequency
0 2 kHz 10 7 kHz
1 2.5 kHz 11 8 kHz
2 3 kHz
12 9 kHz
3 3.5 kHz 13 10 kHz
4 4 kHz 14 11 kHz
5 4.5 kHz 15 12 kHz
6 5 kHz 16 13 kHz
7 5.5 kHz 17 14 kHz
8 6 kHz 18 16 kHz
9 6.5 kHz 19 18 kHz
Note:
For frequencies higher than 6 kHz, please consult LEROY-
SOMER. For the POWERDRIVE FX , the switching frequency
must be ≥ 4 kHz (4).
Used to set the switching frequency when the motor frequency/
speed is below the threshold defined in 05.61 .
05.61 : Switching frequency threshold
Adjustment range : 0.00 to 590.00 Hz
Factory setting : 0.00 Hz
Format: 32 bits
If the motor frequency (speed) is below the threshold set by
05.61 , the switching frequency selected via 05.60 is used.
Otherwise, the switching frequency 05.18 is used.
Reminder: F = (pp x N)/60, where F is the frequency in Hz, pp
the number of pairs of poles and S the speed in rpm.
Note:
For the POWERDRIVE FX , when 05.60 < 4 kHz, the actual
trip threshold is the smallest value between 05.61 and 1/15 of
the motor rated frequency 05.06
05.62 : Torque/speed optimisation for synchronous
motor
Adjustment range : Standard (0), Fixed (1),
Optimized mode 1 (2), Optimized mode 2 (3)
Factory setting : Standard (0)
Format: 8 bits
This parameter is only active when 11.31 is on Servo (3).
Standard (0):
The drive regulates a zero magnetising current in the motor
(corresponds to the majority of applications).
Fixed (1):
The drive imposes in line with the pole axis a current set by
05.63 (visible in 04.17 ).
Optimized mode 1 (2):
The drive imposes in line with the pole axis a current proportional
to the active current. The proportionality slope is set by 05.63
which corresponds to the demagnetising current desired at the
motor rated current 05.07 .
Optimized mode 2 (3):
The drive imposes in line with the pole axis a current defined
according to the typical motor parameters ( 05.24 , 05.33 ,
05.51 ).
In all cases, when the drive output voltage reaches its limit
(defluxing range), the pole axis current is then imposed by
automatic defluxing.
Note:
Leave 05.62 = Standard (0) and only change after consulting
LEROY-SOMER.
05.63
:
Optimal magnetising current
Adjustment range : 0.00 to 2.2 x 11.32
Factory setting : 0.00 A
Format: 32 bits
CAUTION:
This parameter is only active when 11.31 is on Servo (3).
When 05.62 equals Fixed (1) or Optimized mode 1 (2), 05.63
is used to set the optimum magnetising current for synchronous
motors (see explanations in parameter 05.62 ).
When 05.62 is on Standard (0), the value programmed in
05.63 can be used to brake the motor more quickly by
increasing the losses in the motor during braking phases. To
do this, set 02.04 to Fixed ramp + (3) or Automatic ramp + (2).
05.64 : Starting threshold (synchronous motor)
Adjustment range : 0% to 100% of 05.08
Factory setting : 10%
Format: 8 bits
Used to set the speed at which the injection of a current to help
with starting a permanent magnet synchronous motor is
cancelled (see 05.52 ).
