Introduction

1-3-2 Software Ver. VSG101043

H CompoBus/D Communications Improved
The following functions were added for DeviceNet communications using a CompoBus/D Communica-
tions Card.
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.
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.
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 Vector 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.
