J Monitor Function
The following items can be monitored with the Digital Operator: Frequency reference, output frequency,
output current, motor speed, output voltage reference, main-circuit DC voltage, output power, torque ref-
erence, status of input terminals, status of output terminals, operating status, total operating time, software
number, speed deviation value, PID feedback value, fault status, fault history, etc.
All types of data can be monitored even with multi-function analog output.
J Bilingual Digital Operator
The Digital Operator can display either English or Japanese. The Digital Operator’s liquid crystal display
provides a 16-character x 2-line display area.
Easy-to-read displays allow the advanced functions of the Inverter to be set in interactive operations to
input constants, monitoring items, etc. Change the constant setting to select the English display.
J Harmonic Countermeasures (0.4 to 160 kW Models)
The VS-626MC5 Inverters support DC reactors to easily handle high-frequency control guidelines.
D DC reactors (optional) can be connected to 0.4 to 15 kW models.
D Models from 18.5 to 75 kW have a built-in DC reactor.
J User Constant Structure and Three Access Levels
The VS-626MC5 has a number of user constants for setting various functions. These user constants are
classified into a hierarchy to make them easier to use.
The levels are as follows from top to bottom: Modes, Groups, Functions, and Constants. The access levels
for the user constants are shown in Table 1.3.

1.3 Access Levels for User Constants
Level Contents
Mode Classified according to operation
Operation:
For operating the Inverter. (All kinds of monitoring are possible.)
Initialize: For selecting the language displayed at the Digital Operator, set-
ting access levels, initialization, and the control modes.
Programming: For setting user constants for operation.
Autotuning: For automatic calculation or setting motor constants. (Only under
the vector control mode.)
Modified constants: For referencing or changing user constants after shipping.
Groups Classified by application.
Functions Classified by function. See user constants.
Constants Individual user constant settings.
The VS-626MC5 allows the following three access levels to be set in order to further simplify setting user
constants. (An access level is a range of user constants that can be referenced or set.)
Quick-Start Reads/sets user constants required for trial operation. [Factory setting]
Basic Reads/sets user constants that are commonly used.
Advanced Reads/sets all the user constants that can be used.
