Danfoss VLT Midi Drive FC-280P4K0 [87/136] Notice

Danfoss VLT Midi Drive FC-280P4K0 [87/136] Notice
14-21 Automatic Restart Time
Range: Function:
10 s* [0 - 600
s]
Enter the time interval from trip to start of the
automatic reset function. This parameter is
active when parameter 14-20 Reset Mode is set
to [1]–[13] Automatic reset.
14-22 Operation Mode
Option: Function:
Specify normal operation, perform tests, or
initialize all parameters except for
parameter 15-03 Power Up's,
parameter 15-04 Over Temp's, and
parameter 15-05 Over Volt's. This function is
only active when the power is cycled to the
frequency converter.
[0]
*
Normal
operation
Normal operation with motor selected.
[2] Initiali-
sation
Reset all parameter values to default settings,
except for parameter 15-03 Power Up's,
parameter 15-04 Over Temp's, and
parameter 15-05 Over Volt's. The frequency
converter resets during the next power-up.
14-24 Trip Delay at Current Limit
Range: Function:
60 s* [0 -
60 s]
Enter the current limit trip delay in seconds. When
the output current reaches the current limit
(parameter 4-18 Current Limit), a warning is
triggered. When the current limit warning has
been continuously present for the period specied
in this parameter, the frequency converter trips. To
run continuously in current limit without tripping,
set the parameter to 60 s=O. Thermal monitoring
of the frequency converter remains active.
14-25 Trip Delay at Torque Limit
Range: Function:
60 s* [0 -
60 s]
Enter the torque limit trip delay in seconds. When
the output torque reaches the torque limits
(parameter 4-16 Torque Limit Motor Mode and
parameter 4-17 Torque Limit Generator Mode), a
warning is triggered. When the torque limit
warning has been continuously present for the
period specied in this parameter, the frequency
converter trips. Disable the trip delay by setting
the parameter to 60 s=O. Thermal monitoring of
the frequency converter remains active.
14-27 Action At Inverter Fault
Option: Function:
Select how the frequency converter reacts when
an overvoltage or grounding fault occurs.
14-27 Action At Inverter Fault
Option: Function:
[0] Trip Disables the protection lters and trips at the rst
fault.
[1] * Warning Runs the protection lters normally.
14-28 Production Settings
Option: Function:
[0] * No action
[1] Service reset
[3] Software Reset
14-29 Service Code
Range: Function:
0* [0 - 0x7FFFFFFF ] For internal use only.
14-30 Current Lim Ctrl, Proportional Gain
Range: Function:
100 %* [0 - 500 %] Enter the proportional gain value for the
current limit controller. Selection of a high
value makes the controller react faster. Too
high a setting leads to controller
instability.
14-31 Current Lim Ctrl, Integration Time
Range: Function:
0.020 s* [0.002 - 2 s] Controls the current limit control
integration time. Setting it to a lower
value makes it react faster. A setting too
low leads to control instability.
14-32 Current Lim Ctrl, Filter Time
Range: Function:
5 ms* [1 - 100 ms] Sets a time constant for the current limit
controller low-pass lter.
14-40 VT Level
Range: Function:
66 %
*
[40 -
90 %]
NOTICE
This parameter cannot be adjusted while
the motor is running.
NOTICE
This parameter is not active when
parameter 1-10 Motor Construction is set to
options that enable PM motor mode.
Enter the level of motor magnetization at low
speed. Selection of a low value reduces energy
loss in the motor, but also reduces load
capability.
