F-6 ModbusRTU Setup
3AXD50000011888
For the CTD firmware only, a few additional bits have been added to the Main Status Word (SW) in par 6.11:
Status Word Bit #
Function
10
Trickle Heating Active (on during delay and heating)
11
De-Ice Mode Active
12
CTDD Running (motor actually turning – ***not active in de-ice mode***)
13
CTDD Hold (autophasing in progress)
The rest of the usual SW bits still work, although they should be carefully interpreted. For example, the running bit will come
on during motor trickle heating even though the motor isn’t actually turning (drive is modulating though!). The most useful
bits to the customer will be:
Bit 1: Drive Ready
Bit 3: Drive Faulted
Bit 7: Drive Warning
Bit 9: Drive Keypad in Remote mode
