ACS 600 Master/Follower Application Macro 4-3
11.03 EXT REF1
SELECT
External reference 1 is the speed reference. This parameter chooses
the signal source of External reference 1. The selection is illustrated in
the control connection diagrams (see Appendix A – Control Signal
Connections ).
KEYPAD; ... ; DI5U,6D
See the
Firmware Manual .
COMM. REF
Overriding system via channel CH0 or CH2 of the NAMC board is the
source of External reference 1. In the Follower,
Reference 1 received
from the Master is External reference 1.
COMMREF+AI1
Overriding system via channel CH0 or CH2 of the NAMC board
together with Analogue input AI1 are the sources of External reference
1. In the Follower,
Reference 1 received from the Master is added to
the rpm value converted from the analogue signal connected to AI1.
COMMREF*AI1
Overriding system via channel CH0 or CH2 of the NAMC board
together with Analogue input AI1 are the sources of External reference
1. In the Follower,
Reference 1 received from the Master is multiplied
with the rpm value converted from the analogue signal connected to
AI1.
11.06 EXT REF2
SELECT
External reference 2 is the torque reference. This parameter chooses
the signal source of External reference 2. The selection is illustrated in
the control connection diagrams (see
Appendix A – Control Signal
Connections) . For selections KEYPAD; ... ; DI5U,6D see the Firmware
Manual .
COMM. REF
Overriding system via channel CH0 or CH2 of the NAMC board is the
source of External reference 2. In the Follower,
Reference 2 received
from the Master is External reference 2.
COMMREF+AI1
Overriding system via channel CH0 or CH2 of the NAMC board
together with Analogue input AI1 are the sources of External reference
2. In the Follower,
Reference 2 received from the Master is added to
the % value converted from the analogue signal connected to AI1.
COMMREF*AI1
Overriding system via channel CH0 or CH2 of the NAMC board
together with Analogue input AI1 are the sources of External reference
2. In the Follower,
Reference 2 received from the Master is multiplied
with the % value converted from the analogue signal connected to AI1.
