Description
(Visible when 14.1 Module 1 type
Defines the deactivation delay for digital input/output
DIO2.
See parameter 14.12 DIO1 ON
Deactivation delay for DIO2.
(Visible when 14.1 Module 1 type
Selects how the drive reacts when an analog input
signal moves out of the minimum and/or maximum
limits specified for the input.
The inputs and the limits to be observed are selected
by parameter 12.4 AI supervision
No action taken.

Drive generates a warning
Warning) and freezes the speed (or frequency) to the
level the drive was operating at. The speed/frequency
is determined on the basis of actual speed using
850 ms low-pass filtering.

Make sure that it is safe to continue operation
in case of a communication break.
Drive generates a warning

Selects whether DIO3 of the extension module is used
as a digital input or output.
DIO3 is used as a digital output.
DIO3 is used as a digital input.
(Visible when 14.1 Module 1 type
Specifies the analog input limits to be supervised. See
parameter 14.19 AI supervision
Note: The number of active bits in this parameter
depends on the number of inputs on the extension
module.
1 = Minimum limit supervision of AI1 active.
1 = Maximum limit supervision of AI1 active.
