Unit Description / Notes
0.0 to 1235
Indicates the inverter DC Link voltage in volt (V).
[ - ]
1 V
0.0 to 1020 Indicates the inverter output frequency in hertz (Hz).
[ - ]
0.1 Hz
Indicates the inverter status:
[ - ]
rdy- inverter is ready to be started or enabled;
-
run- inverter is enabled;
Sub- inverter is disabled and line voltage is too low for operation
(undervoltage);
Exy- inverter is in a fault condition, 'xy' is the number of the Fault code,
example: E06.
0 to 800 Indicates the inverter output voltage in volt (V).
[ - ]
1 Vac
Indicates the torque developed by the motor. It is determined as follows:
0.0 to 150.0
[ - ]
0.1 %
Where:
Tm = Measured motor torque current
I = Nominal motor torque current given by:
Tm
N = Speed
I =
Tm
X = P410 x
0.0 to 3276
Indicates the instantaneous output power in kilowatt (kW).
[ - ]
0.1 kW
Indicates on the Keypad LCD display the status of the 6 digital inputs of
LCD = 1 or 0
the control board (DI1 to DI6), and the 2 digital inputs of the I/O Expansion
Board (DI7 and DI8). Number 1 stands for Active (DIx closed) and number
[ - ]
0 stands for Inactive (DIx open), in the following order:
-
DI1, DI2, ... , DI7, DI8.
The LED display shows a decimal value related to the 8 Digital Inputs,
where the status of each input is considered one bit of a binary number
