PARAMETER DESCRIPTIONS
750 COOLING MONITOR 6 (2.2.7.23)
Use this parameter to select the digital input signal that shows the state of the used cooling
unit. This parameter is used for liquid-cooled AC drives.
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 the VACON
751 COOLING FAULT DELAY 6 (2.7.32)
Use this parameter to set the delay after which the AC drive goes to FAULT state when there
is no 'Cooling OK' signal.
752 SPEED ERROR FAULT FUNCTION 6 (2.7.33)
Use this parameter to select the fault response when the speed reference and the encoder
speed exceed the set limits.

753 SPEED ERROR MAXIMUM DIFFERENCE 6 (2.7.34)
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.
754 SPEED ERROR DELAY 6 (2.7.35)
Use this parameter to set the delay after which the AC drive goes to FAULT state when there
is a speed error.
755 SAFE DISABLE MODE 6 (2.7.36)
Use this parameter to select the response to an activated safe disable mode.
NOTE!
See separate VACON
the Safe Disable function. This function is available only if the drive is equipped with
VACON option board OPTAF.
