6.1 Basic settings
The NORDAC trio SK 300E is already set up so that the assigned 4-pole standard motor can be operated
without further presetting.
The frequency inverter is not equipped with a line main switch and is therefore always live when connected to
the power supply. It waits with a blocked output until an enable signal occurs.
Attention
If a digital input is not programmed for enable and the parameter P428 is changed to 2 (=
"Immediate with mains“), the motor will start immediately, as all enable conditions have been met.
The following options for an enable signal are available:
1) An enable signal is generated by pressing the start key when a ParameterBox is connected.
See "Initial check with ParameterBox“on Page 73 .
2) When connected to a PC, an enable can be generated with the START key in the "NORD CON" control
software (see Chapter 5 "NORD CON software", Page 70).
3) An "Enable right" is implemented with the factory setting if a control input is configured, e.g. digital input
2 on the CU Basic I/O or Standard I/O (terminal 22), with the internal 15V supply voltage (terminal 42).
4) By changing the "Automatic start up" parameter P428 to 2 (= "Immediate with mains"), this enable
occurs as soon as the mains voltage is switched on. The requirement for this is that no digital input has
been parameterised for Enable.
Note
In delivery condition, only the most important parameters are visible for eventual parameter
changes. Should it be necessary to change other parameters as well, such as e.g. motor data when
using a different motor, then parameter P003 "Supervisor Mode" must be set to 1, so that all
parameters are visible (see also parameter P003 Æ, Page
78 )!!!
Visible parameters in delivery condition:
Supervisor mode switched off (P003 = 0), i.e. only a limited number of parameters are visible, all other
parameters are hidden:
