1-2-1 Model-specific tables for 200 V and 400 V class inverters
The following tables are specific to MX2 inverters for the 200 V and 400 V
class model groups. Note that General Specifications on page 7 in this chap-
ter apply to both voltage class groups. Footnotes for all specification tables fol-
low the table below.
Footnotes for the preceding table and the tables that follow:
Note 1 The protection method conforms to JEM 1030.
Note 2 The applicable motor refers to a standard 3-phase motor (4p). When using
other motors, care must be taken to prevent the rated motor current (50/
60 Hz) from exceeding the rated output current of the inverter.
Note 3 The output voltage decreases as the main supply voltage decreases (except
when using the AVR function). In any case, the output voltage cannot exceed
the input power supply voltage.
Note 4 To operate the motor beyond 50/60 Hz, consult the motor manufacturer for the
maximum allowable rotation speed.
Note 5 For achieving approved input voltage rating categories:
• 460 to 480 VAC - Over-voltage category 2
• 380 to 460 VAC - Over-voltage category 3
To meet the Over-voltage category 3, insert an EN or IEC standard compliant
isolation transformer that is earth grounded and star connected (for Low Volt-
age Directive).
Note 6 At the rated voltage when using a standard 3-phase, 4-pole motor.
Note 7 The braking torque via capacitive feedback is the average deceleration torque
at the shortest deceleration (stopping from 50/60 Hz as indicated). It is not
continuous regenerative braking torque. The average deceleration torque var-
ies with motor loss. This value decreases when operating beyond 50 Hz. If a
