H
Protection Setting for Motors for Vector Control (Parameter E1-02)
A special protection setting has been provided for vector-control motors, which have high resistance to
overloads even at low speeds.
H
Bias Function for Analog Monitor Cards (Parameters F4-05 and F4-06)
A bias function has been added to the analog output from Analog Monitor Cards to enable adjusting the
offset voltage.
H
NC Contact Emergency Stop Function for Multi-function Inputs
(Parameters d3-01 to d3-04)
An NC contact emergency stop function has been added to the previous NO function.
H
Bias Function for Reverse Motor Control for Multi-function Inputs
(Parameters H3-05 and H3-09)
A function has been added for reverse motor operation by establishing a frequency bias 2 (setting: D)
for the multi-function inputs that causes reverse operation when the sum of the bias values is negative.
H
Run Command Selection Outside of Drive Mode (Parameter b1-08)
A function has been added to enable or disable run command inputs in mode other than Drive Mode,
e.g., Program Mode or Initialize Mode.
Note If this function is used, a run command can be input and Inverter operation stared even when
adjusting parameters in Program Mode. Proper safety measures must be taken to prevent dan-
gerous situations.
H
Motor Core Loss Adjustment for Torque Compensation (Parameter
E2-10)
A motor core loss setting has been added to enable fine adjustment of torque compensation (totally
automatic torque boast) in V/f control without PG and V/f control with PG control modes.

Changes in Default Settings and Setting Ranges
The defaults and setting ranges for the following parameters have been changed for applications.
D
Cumulative Operation Time Display Change (Parameter o2-07)
Previously 0 was display when the default value was set for the cumulative operation time, but this has
been changed to display the current cumulative operation time as the default.
