5.2.5 Motor Parameter Autotune
The procedure of motor parameter autotune is as follows:
At first, choose the keyboard command channel as the operation command channel
(P0.01).
And then input following parameters according to the actual motor parameters:
P2.01: motor rated frequency;
P2.02: motor rated speed;
P2.03: motor rated voltage;
P2.04: motor rated current;
P2.05: motor rated power.
Important note: the motor should be uncoupled with its load; otherwise, the motor
parameters obtained through autotune may be not correct. Set P0.17 to be 1, and for the detail
process of motor parameter autotune, please refer to the description of Function Code P0.17.
And then press Button RUN on the keyboard panel, the inverter will automatically calculate
following parameter of the motor:
P2.06: motor stator resistance;
P2.07: motor rotor resistance;
P2.08: motor stator and rotor inductance;
P2.09: motor stator and rotor mutual inductance;
P2.10: motor no-load current; then motor autotune is finished.
5.2.6 Password Setting:
CHV series inverter provides user’s cryptoguard function. When P7.00 is set to be nonzero,
it is the user’s password, and exiting function code edit mode will make the password become
effective. If pressing Button PRG/ESC again to try to access the function code edit mode,
“-----”will be displayed, and the operator must input correct user’s password, otherwise will be
unable to access it.
If it is necessary to cancel the cryptoguard function, just set P7.00 to zero. User’s
cryptoguard has no protection to the parameters in shortcut menu.
5.3 Running State
5.3.1 Power-on Initialization
The system first conducts initialization during the inverter power-on, and LED displays
“-CHV-”. After the initialization is completed, the inverter is on stand-by status.
5.3.2 Stand-by
At stop or running state, parameters at multiple states can be displayed. Whether or not to
display this parameter can be chosen through Function Code P7.06 (running parameter) and
P7.07 (stop parameter) according to binary bits, which definitions can be seen in
function-code-description of P7.06 and P7.07.
Under stop state, there are total sixteen stop state parameters which can be chosen
whether to display or not. They respectively are: set frequency, bus voltage, on-off input status,
open collector output status, PID setting, analog input AI1 voltage, analog input AI2 voltage,
analog input AI3 voltage, analog input AI4 voltage, high speed pulse input 1 (HDI1), high
