Note:
 After commissioning is completed, to conveniently record and query the modified parameters.
 When perform on-site maintenance, to conveniently record and query the modified parameters.
3: Last changed T0 parameters menu mode: The last changed T0 parameters can be inquired.
Note:
 Both P0.00 and P0.0T are visible in all menu modes for the convenience of menu mode switched.
 Press ESC key and hold for over 5 seconds, it will restore to basic menu mode, and P0.0T is
automatically restored to 0.
 In non basic menu mode, the >> key cannot be used to switch the parameter and group number. The
−
current menu mode will be displayed after pressing the >> key for 5 times.
P0.03
The parameter is used to set the motor control mode.
0: Process open loop control:
It is applicable to most applications, including the application of multiple motor with a single inverter
(the motors are in the same work conditions, such as gantry of crane).
T: Analog feedback process close loop control:
This function can be used for closed loop control of system variables such as pressure, temperature,
etc. The difference between the reference and the feedback value is fed into the PID controller. The
PID controller adjusts the output frequency in order to minimize the deviation of reference and
feedback, providing accurate control of system variables.
For the reference setting and feedback setting of the analog feedback process close loop control,
refer to the descriptions of PT.0T~PT.07.
AIT and AIT analog input specification: 0~T0V or 0~T0mA.
AI3 analog input specification: −T0~T0V.
X7TDI pulse input specification: 0~ maximum input pulse frequency P5.T0.
For the setting of the process PID close loop, refer to parameter descriptions in Group P8 .
T: Single-phase pulse feedback process close loop control:
It is applicable to applications with higher speed control precision, and pulse encoder shall be installed.
Single-phase pulse feedback channel is X7TDI terminal, The X7TDI terminal function must be set to
process close loop control single-phase pulse input (P5.06=47) .
3: Composite control:
The composite control of process open loop and analog feedback closed loop is suitable for special
applications. When the inverter running in setting frequency of open loop, and it is necessary to use
process close loop control in the system, and the process close loop adjustment result will be added
to the open loop frequency reference of the inverter, so as to ensure the constancy of the physical
parameter through speed control. Refer to parameter PT.08.
Note:
 AI3 is only available for "E5−H−4T**G−63", "E5−H−4T**G−34" non−standard series and E5−A series.
 Pulse input X7TDI is only available for "E5−H−4T**G−63" non-standard series and E5−A series.
