6. Motor Current:
This position indicates de P003 Parameter content, disregarding the decimal
point. A lowpass filter with a time constant of 0.3 s filters this variable.
The variables are written in the following order:
1 - Logical Control;
2 - Motor speed reference,
for option P309 = 1 or 4 (2I/O) - it writes in 1 and 2;
3 - Status of the Digital Outputs;
4 - Number of the Parameter to be read,
for option P309 = 2 or 5 (4I/O) - it writes in 1, 2, 3 and 4;
5 - Number of the Parameter to be changed;
6 - Content of the Parameter to be changed, selected in the previous position,
for option P309 = 3 or 6 (6I/O) - it writes in 1, 2, 3, 4, 5 and 6.
1. Logical Control (C.L.):
The word that defines the C.L. is formed by 16 bits, being 8 bits of high orders
and 8 bits of low orders and having the following construction:
High-Order Bits - they select the function that shall be driven when the bit is set
to 1.
CL.15 - Inverter fault reset;
CL.14 - Without function;
CL.13 - To save the changes of the parameter P169/P170 in the EEPROM;
CL.12 - Local/Remote control;
CL.11 - Jog control;
CL.10 - Direction of rotation;
CL.09 - General enabling;
CL.08 - Start/Stop.
Low-Order Bits - they determine the status that is wanted for the function selected
in the high-order bits.
CL.7 - Inverter fault reset: always it varies from 0  1, an inverter reset is caused,
with the presence of faults (except E24, E25, E26 e E27);
CL.6 - No function / STOP detection. It is not necessary to activate the
correspondent upper bit (refer to the description of parameter P310);
CL.5 - To save P169/P170 in the EEPROM: 0 = to save, 1 = to not save;
CL.4 - Local/Remote control: 0 = Local, 1 = Remote;
CL.3 - Jog control: 0 = Inactive, 1 = Active;
CL.2 - Direction of rotation: 0 = counter-clockwise, 1 = clockwise;
CL.1 - General enabling: 0 = Disabled, 1 = Enabled;
CL.0 - Start/Stop: 0 = Stop, 1 = Start.
NOTE!
The inverter will execute only the command indicated in the low-order bit, when
the corresponding high-order bit has the value 1 (one). When the high-order bit
has the value 0 (zero), the inverter will disregard the value of the corresponding
low-order bit.
