Using the Digital Operator
The YD5000 Inverter’s user constants and monitoring functions have been organized in groups
called
modes that make it easier to read and set user constants.
The Yd5000 is equipped with 5 modes, as shown in the Table 4.2.

mode
The Inverter can be run in this mode.
Use this mode when monitoring values such as frequency references or output
current, displaying fault information, or displaying the fault history.
Use this mode when selecting the language displayed on the Digital Operator, se
lectingthe access level for reading/setting user constants, selecting the control
mode, or initializing the user constants.
Use this mode when reading/setting the user constants required for operation.
The program-mode functions are subdivided into the following groups:
Application:
Operation mode selection, DC control, speed search, etc.
Tuning:
Acceleration/deceleration times, S-curve characteristics, car
rierfrequencies, etc.
Reference:
Settings related to frequency control
Motor:
V/f characteristics and motor constants
Option:
Settings for Optional Cards
Terminal:
Settings for sequential I/O and analog I/O
Protection:
Settings for the motor and inverter protection functions
Operator:
Selects the Digital Operator’s display and Key functions
(
Usable only with in vector control mode
)
Use this mode when running a motor with unknown motor constants in the vector
control mode. The motor constants are calculated and set automatically.
Use this mode to read/set user constants that have been changed from their factor
ysetvalues.
Note Always perform autotuning before operating in vector control mode. Refer to5.2.5 Autotuning
and 6.4.3 Autotuning for details.
4.2.2 Switching Modes
4.2.2 Switching Modes
Once the Inverter has been put into operation mode by pressing the Menu Key, the Increment
and Decrement
Keys can be pressed to switch to other modes. Press the DATA/ENTER Key
to read/set the userco
nstants in each mode.
Press the ESC Key to return to the mode display from the user constant display.
Press the DATA/ENTER Key twice to write a constant and then press the ESC Key to return
to the modedisplay. This is the most Basic operation, so you should remember it.
