4-2 Establishing Communications
VS-616G5 Parameter Settings
The drive can be configured to receive operation signals ( Run, Stop, Forward, Reverse, ... ) from
the MB+ network, serial communication, the external drive terminals, or the Digital Operator. VS-
616G5 Drive Register b1-02 (181h) is used to setup the source of the operation signals. The
following table indicates the possible configurations for the origin of the operation signals:
RUN / STOP
b1-02 Commands from:
0 Digital Operator
1 Terminal
2 Serial Communication
3 Option PCB (MB+ board)
The drive can be configured to receive a frequency reference from the MB+ network, serial
communication, the external drive terminals, or the Digital Operator. VS-616G5 Drive Register b1-
01 (180h) is used to setup the source of the frequency reference. The following table indicates
the possible configurations for the origin of the frequency reference:
FREQUENCY REFERENCE
b1-01 Commands from:
0 Digital Operator
1 Terminal
2 Serial Communication
3 Option PCB (MB+ board)
The value of VS-616G5 Drive Register b1-01 (180h) and b1-02 (181h) may be stored in Non-
Volatile RAM memory on the drive by use of the ENTER command. After the value has been
‘entered’, that value will be retained if the drive unit is powered down.
Although the settings of b1-01 (180h) and b1-02 (181h) set the origin of the operation and
frequency reference commands, many commands may still be functional from an alternative
source. Appendix B, Command Priority, illustrates the available command origins for various
functions.
