10.67 : User trip 4
Adjustment range : Disabled (0) or Enabled (1)
Factory setting : Disabled (0)
Format: 8 bits
Disabled (0):
The drive has not tripped.
Enabled (1):
The drive trips, decelerates in freewheel mode and generates
a user trip 4 code.
10.68 : Not used
10.69 : TRIP ENABLE TO OFF
Adjustment range : Disabled (0) or Enabled (1)
Factory setting : Disabled (0)
Format: 8 bits
This parameter is used to make drive trips active at standstill.
The trips concerned are: IGBT U, V and W, Autotune, I
IMBALANCED, Encoder break, RECTIFIER Th, Motor PTC,
AI2 loss, AI3 loss, Th IGBT U, V and W, Loss of a motor phase,
UVW invert, Internal ventilation.
10.70 to 10.73 : Not used
10.74 : Preload time
Adjustment range : 1 to 15 s
Factory setting : 1 s
Format: 16 bits
Where the drive manages the preloading of capacitors on the
DC bus ( 10.75 = No (0)), this parameter sets the DC bus
preload time. Used in the specific case of a rectifier supplying
several inverters.
10.75 : Powered by DC bus
Adjustment range : No (0) or Yes (1)
Factory setting : No (0)
Format: 8 bits
No (0):
The drive is connected to an AC supply. The drive manages the
preloading of capacitors on the DC bus.
Yes (1):
The drive is supplied directly on its DC bus. The preloading of
capacitors on the DC bus must be managed externally.
Note:
• When 10.75 = Yes (1), reading of the rectifier temperature is
disabled («RECTIFIER Th» is no longer active).
• 10.75 must be set to Yes (1) for POWERDRIVE Regen
(MD2R) units.
10.76
: Preload contactor closed
Adjustment range : No (0) or Yes (1)
Format: 8 bits
No (0):
Short-circuiting of the DC bus preload system is not permitted.
Yes (1):
Short-circuiting for the DC bus preload system may be
permitted.
Note:
10.76 operates with 10.75 at yes (1). The relay switches
when the bus level has reached approximately 90% of its final
value.
10.77 : 4Q rectifier disable
(
POWERDRIVE FX
drive only)
Adjustment range : No (0) or Yes (1)
Factory setting : No (0)
Format: 8 bits
This parameter is used to disable the 4Q rectifier on
POWERDRIVE FX
drives.
No (0):
The rectifier can restore energy to the mains supply.
Yes (1):
The rectifier works as a simple diode bridge.
10.78 and 10.79 : Not used
10.80 : Auto reset type
Adjustment range :Controlled (0) or Automatic (1),
Auto for 1081, 1082, 1083, 1084 (2),
Auto except 1081, 1082, 1083, 1084 (3)
Factory setting : Controlled (0)
Format: 8 bits
Controlled (0):
Trip reset by a Reset command on the terminals or via the
parameter-setting interface.
Automatic (1):
All trips automatically reset.
Auto for 1081, 1082, 1083, 1084 (2):
Selective reset of trips listed in 10.81 , 10.82 , 10.83 and
10.84 .
Auto except 1081, 1082, 1083, 1084 (3):
Selective reset of all trips except trips listed in 10.81 , 10.82 ,
10.83 and 10.84 .
NB:
For MD2R drives, the regen rectifier automatic reset is only
operational if parameter 18.04 is set to «Synchro x3». The
number of resets is set at 3.
10.81 : Special trip n°1
Adjustment range : 0 to 102
Factory setting : 0
Format: 8 bits
Enter the number of the trip * which should or should not be
reset automatically depending on the setting of 10.80 .
* See the list of trips for parameters 10.20 to 10.29 .
