Now, let’s look at the Control Word bit structure. These are the bits we will turn on and off to control the drive:
Control Word Bit # Function
Decimal number to write into
control word to turn this bit “ON”
0 Trickle Heating 1
1 De-Ice Mode 2
2 Start Forward 4
Turning a bit ON will cause that function to start. Only one function should be ON at a time.
So, let’s tell the drive to start and run at 100rpm:
Write a value of 100 to REF1 for the speed reference. (100rpm)
Set CW bit 2=1 by writing a decimal value of 4 to the CW. (drive should start)
Note! If you have set par 53.01 = 23.12, then make sure to also write a value into register 40004 for the Accel Time 1.
Try “300” for 30 seconds. If left empty, Modbus Poll will write a value of zero into this parameter. An accel time of zero is
unreasonable and may cause a drive fault.
For the CTD rmware 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)
