A fault is generated if the input is low when the drive is in
RUN
state. If the drive is in
STOP
state, only warning is generated. See
VACON

NXP Liquid-Cooled Drives User Manual.
10.374 (ID 751) Cooling Fault Delay
Location in the menu:
P2.7.32
(Multi-purpose Control Application)
Use this parameter to set the delay after which the AC drive goes to
FAULT
state when there is no 'Cooling OK' signal.
10.375 (ID 752) Speed Error Fault Function
Location in the menu:
P2.7.33
(Multi-purpose Control Application)
Use this parameter to select the fault response when the speed reference and the encoder speed exceed the set limits.
10.376 (ID 753) Speed Error Maximum Difference
Location in the menu:
P2.7.34
(Multi-purpose Control Application)
Use this parameter to set the maximum difference between the speed reference and the encoder speed. When the difference goes
outside this limit, a fault occurs.
The speed error refers to the difference between the speed reference and the encoder speed. This parameter defines the limit when
a fault is generated.
10.377 (ID 754) Speed Error Delay
Location in the menu:
P2.7.35
(Multi-purpose Control Application)
Use this parameter to set the delay after which the AC drive goes to
FAULT
state when there is a speed error.
10.378 (ID 755) Safe Disable Mode
Location in the menu:
P2.7.36
(Multi-purpose Control Application)
Use this parameter to select the response to an activated safe disable mode.
See separate VACON
®
NX OPTAF (STO) Board Manual for detailed information on the Safe Disable function. This function is available
only if the drive is equipped with VACON
®
option board OPTAF.
With this parameter, it is possible to select whether the activated safe disable function is responded as fault or warning. The safe
disable input stops the drive modulation regardless of this parameter value.
10.379 (ID 756) Safe Disable Active
Location in the menu:
P2.3.3.30
(Multi-purpose Control Application)
Use this parameter to select the digital output signal that shows the status of the Safe Disable.
10.380 (ID 762) Cooling Fault Response
Location in the menu:
P2.7.48
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to select the response to a cooling fault.
Sometimes it is more important to allow the drive to run even if the coolant is not circulating. In this case select warning as the
response. The drive will continue running until its internal protection stops it. If cooling signal loss happens in Stop state, the indica-
tion is not stored in fault history if the previous fault is already a Cooling Fault. In Run state, the indication is always stored in fault
history.
