Introduction
Parameter Settings for Second Motor (Parameters E5-01 to E5-06)
Parameter settings were added so that different parameters can be set for the second motor.
H Inverter Output Noise Reduction
The noise output by 400-V class Inverters was reduced to reduce the affect on peripheral devices and
conform to EN standards. The following function improvements were added to support noise reduction.
Default Setting Change for Carrier Frequency (Parameters C6-10 to C6-03)
The default carrier frequency setting for 400-V class Inverters was changed for the reduction of output
noise.
Inverter Overload Function Change (OL2 Detection)
The Inverter overload detection function was changed because the Inverter's rated output current
would be reduced if it was set higher than the carrier frequency.
Note If an Inverter overload is detected before a motor overload (0L1), lower the Inverter's carrier fre-
quency setting.
H Operation Selection after Switching to Remote Mode (Parameter b1-07)
Operation can be switched between Digital Operator and the frequency reference (b1-01) and between
Digital Operator and the run command (b1-01) by setting the local/remote selection using the Digital
Operator's operation mode selection key or multi-function inputs (H1-01 to H1-06). The new function
can be used to enable or disable run commands when switching between the two forms of operation.
Note If the run command is enabled when switching operation, the Inverter can start operation immedi-
ately after switching operation. You must take appropriate safety measures when using this func-
tion.
H PG Disconnection Detection (PGO) Detection Time Setting (Parameter
F1-14)
A setting for PG disconnection (PGO) was added so that the detection time can be adjusted.
H New Functions for Multi-function Inputs 1 to 6 (H1-01 to H1-06)
The following functions were added to the multi-function inputs.
Sample/hold function for the analog frequency reference (setting: 1E)
PID control integral reset (setting: 30)
H Constant Output Area Settings for Flux Vector Control (E1-11 to E1-13)
Settings were added to enable controlling V/f characteristics to compensate voltage increases caused
by motor impedance when special motors, such as constant power-output motors and machine tool
shaft motors, are used in the constant output area.
H Vector Control Adjustment Settings (C3-05, C5-08, C8-09, C8-30)
Adjustment functions were added for vector control.
