4.2 Modes
This section describes the VS-616G5’s monitor modes, switching between modes, and accessing/setting user
constants.
4.2.1 Inverter Modes
The VS-616G5 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 VS-616G5 is equipped with 5 modes, as shown in the Table 4.2.
Table 4.2 Modes
Mode Primary function(s)
Operation mode
The Inverter can be run in this mode.
Use this mode when monitoring values such as frequency references or output cur-
rent, displaying fault information, or displaying the fault history.
Initialize mode
Use this mode when selecting the language displayed on the Digital Operator, select-
ing the access level for reading/setting user constants, selecting the control mode, or
initializing the user constants.
Programming mode
Use this mode when reading/setting the user constants required for operation.
The program-mode functions are subdivided into the following groups:
S Application: Operation mode selection, DC control, speed search, etc.
S Tuning: Acceleration/deceleration times, S-curve characteristics, carrier fre-
quencies, etc.
S Reference: Settings related to frequency control
S Motor: V/f characteristics and motor constants
S Option: Settings for Optional Cards
S Terminal: Settings for sequential I/O and analog I/O
S Protection: Settings for the motor and inverter protection functions
S Operator: Selects the Digital Operator’s display and Key functions
Autotuning mode
(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.
Perform autotuning for motor unit separately before vector control operation.
Modified constants
mode (See note)
Use this mode to read/set user constants that have been changed from their factory-
set values.
Note Always perform autotuning for motor unit separately bofore vector control operation.
