Connection of the converter and the inverter
40
2.5.2
Switching between the common bus
regeneration mode and the power regeneration
mode
• Switch the converter connection mode between the common bus regeneration mode
and the power regeneration mode by changing the position of switch 1 in the function
selection switch assembly (SW2).
NOTE
• The new setting of the switch is applied at the next power-ON or converter reset.
• If the switch 1 setting (the connection mode setting) does not match the actual wiring of the main circuit terminals, the
connection mode fault "E.T" occurs.
2.5.3
Function enable/disable selection (Pr.416)
• Select the function status by setting
Pr.416
.
NOTE
• The change of the
Pr.416
setting is applied at the next power-ON or converter reset.
• If the harmonic suppression function is attempted to be enabled in the FR-XC-15K or lower, the fault "E.U" (Unsupported
function selected) occurs.
2.5.4
Inverter parameter settings
To use the converter with the inverter,
Pr.30 Regenerative function selection
in the inverter parameters must be set. The
parameter setting differ by the inverter series.
Refer to the Instruction Manual of the Inverter.
• To use the converter in the common bus regeneration mode, select the setting for a power regeneration common converter
or high power factor converter (Example:
Pr.30
in the FR-A800 = "2"). When
Pr.416
= "1", set the rated motor voltage in
Pr.19 Base frequency voltage
(under V/F control) or
Pr.83 Rated motor voltage
(under control other than V/F control).
• To use the converter in the power regeneration mode, set "0" in
Pr.30
in any inverter irrespective of model and capacity.
NOTE
• Set
Pr.30
in the inverter parameters correctly according to the converter operation mode (common bus regeneration mode or
power regeneration mode). Incorrect setting may disrupt normal operation.
2.5.5
Temperature derating selection
The temperature rating changes according to the setting position of the switch 3 in the function selection switch assembly
(SW2).
When the 40°C rating is selected, the rated current and the applied current can be increased.
When the 40°C rating is selected, the surrounding air temperature must be between -10 and +40°C (non-freezing).
NOTE
•
The new setting
of the
switch
is applied at the next power-ON or converter reset.
