Table 6- 59 Default output process image (master to slave) - Dual slave mode
DO0 Motor control bit 0
0 0 0 OFF1
0 0 1 Fixed frequency 1 (default 50 Hz)
0 1 0 Fixed frequency 2 (default -50 Hz)
0 1 1 Fixed frequency 3 (default 10 Hz)
1 0 0 Fixed frequency 4 (default 15 Hz)
1 0 1 Fixed frequency 5 (default 20 Hz)
1 1 0 Fixed frequency 6 (default 25 Hz)
1 1 1 With active trip: Fault ACK (1)
DO2 Motor control bit 2
DO3 A / B select 0: 'A' slave active
Slave 1
Clock signal for CTT2 data transfer from AS-i master
Data signal for CTT2 data transfer from AS-i master
DO2 Quickstop override 0: Quick stop active
1: Quick stop override: allow Inverter to ignore quick stop
DO3 A / B select 0: 'A' slave active
(1) The AS-i specification mandates the simultaneous use of ‘Motor Left’ and ‘Motor Right’ as fault acknowledge, particu-
larly if there is no spare input available for this function.
(2) If no fault is active then simultaneous operation of ‘Motor Left’ and ‘Motor Right’ constitutes a process image error. In
this state both the inverter motor outputs and the motor holding brake outputs are inactive, causing the motor to coast to a
halt and engaging the motor holding brake in exactly the same way as an OFF2 command. This state is maintained until
both ‘Motor Left’ and ‘Motor Right’ are deactivated at the same time.
Table 6- 60 Default input process image (slave to master) - Single slave mode
DI0 Ready 0: Inverter is not responsive to AS-i master
1: Inverter is ready to respond to commands from the AS-i master
DI1 Motor active 0: Inverter motor outputs are high impedance
1: Inverter motor outputs are active
DI2 Digital input 1 0: Input 1 is inactive
DI3 Digital input 2 0: Input 2 is inactive
