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.
H 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.
