H CompoBus/D Communications Improved
The
following functions were added for DeviceNet communications using a CompoBus/D
Communica
-
tions Card.
D Network Reference/Network Control Support (CompoBus/D Communications
Remote I/O)
A
function was added to switch between inputting the Inverter frequency reference and a run command
using CompoBus/D communications from remote I/O. The Network Reference Bit can be turned ON
and OFF to switch between the method set for the frequency reference selection (b1-01) and a fre-
quency reference from communications. In the same way, the Network Control Bit can be turned ON
and OFF to switch between the method set for the run source selection (b1-02) and a run command
from communications.
D Selection of Operation for Communications Errors (Parameter F9-06)
A setting
was added to select the operation of the Inverter when a communications error is detected.
The
selection can be made according to the application, e.g., a deceleration stop,
free-run stop, contin
-
uing operation, etc.
D Torque Limit/Torque Reference Operation Selection via Communications
(Parameter F9-05)
A
function was added to set the torque limit and torque reference (for torque control) from communica
-
tions.
This enables controlling torque operation from
communications when the vector with PG control
mode is used.
Note The
CompoBus/D Communications Card does
not support the torque limit/torque reference func
-
tion. Leave this function disabled.
H V/f Control with PG and Flux Vector Control for Two-motor Switching
Control (Parameter E3-01)
Settings
were added for V/f Control with PG and Flux V
ector Control to the control modes
for the second
motor, enabling feedback control of 2 motors with 1 Inverter.
Note 1. Wiring for the pulse generator or encoder must be switched between the two motors.
Note 2. Use
a pulse generator with the same specifications for both motors. (There is only one group
of parameters for the pulse generator.)
H Motor Parameter Autotuning (Parameter C8-30)
An autotuning function was added to autotune the motor parameters for special motors.
H Ground Fault Protection Operation Selection (Parameter: L8-10)
A setting was added to enabled and disable ground fault protection so that it can be disable when
required by the application.
