5 Parameter
WARNING Unexpected movement due to parameter changes
Parameter changes become effective immediately
. Dangerous situations can occur under certain conditions,
even when the drive is stationary. Functions such as P428 "Automatic Start" or P420 "Digital inputs" or the
"Release Brake" setting can put the drive in motion and put persons at risk due to moving parts.
Therefore:
• Changes to parameter settings must only be made when the frequency inverter is not enabled.
• During parametrisation work precautions must be taken to prevent unwanted drive movements (e.g. lifting
gear plunging down). The danger area of the system must not be entered.
The relevant parameters for the device are described in the following. The parameters are accessed
using a parametrisation tool (e.g. NORDCON software or control and parametrisation unit, see also
(

Section 3.1 "Control and parametrisation options ") and therefore makes it possible to adapt the
device to the drive task in the best possible way. Different device configurations can result in
dependencies for the relevant parameters.
The parameters can only be accessed if the control unit of the device is active.
The device must be provided with a 24 V DC control voltage to do this (

Section 2.3.3 "Electrical
connection of the control unit").
Connections and possible priority switching with the potentiometers (
P1 …) and the DIP switch ( S1 )
are described in a suitable location and must be taken into consideration (pay attention to
P130
).
Parameter changes only have a direct influence on the RAM memory of the device and are therefore
volatile. In order to retain these changes, a copy job ( P550 ) must be triggered after completing the
parameter changes. This causes the data to be transferred to the permanent memory (Flash memory)
of the device.
The individual parameters are functionally combined in groups. The first digit of the parameter number
indicates the assignment to a
menu group
:
Menu group No. Master function
Operating displays (P0--) Display of parameters and operating values
Basic parameters
(P1--) Basic device settings such as behaviour when switching on/off
Motor data (P2--) Electrical settings for the motor (motor current or starting voltage (start-off
voltage))
Control terminals
(P4--) Assignment of functions for the inputs and outputs
Additional parameters (P5--) Priority monitoring function and other parameters
Information (P7--) Display of operating values and status messages
Information
Factory setting P523
The factory settings of the entire parameter set can be loaded at any time using parameter P523 . For example,
this can be useful during commissioning if it is not known which device parameters have been changed earlier,
and could have an unexpected influence on the operating behaviour of the drive.
Restoring the factory settings (
P523
) affects all parameters. This means that all motor data must subsequently be
checked or reset.
The potentiometers
(P1-P4)
and DIP switches
(S1)
are also reactivated.
