Example Sequence
To start the velocity mode, the correct sequence has to be sent from the PLC.
1 Control word =
0x0000
Disable voltage
1 Status word =
0x0050 Switch On Disabled
2 Modes of Operation = 2
(Velocity mode)
3 Control word =
0x0006
Shutdown
Status word =
0x0031 Ready to switch on
4 Control word =
0x0007
Switch On
Status word =
0x0033 Switched On
5 Control word =
0x000F
Enable Operation, no change to previous
state if already enabled.
Status word =
0xnn37 Operation enabled
6a Control word =
0x007F
Start Velocity mode with Reference speed
Status word =
0xnn37 Operation enabled
6b Control word =
0x006F
1299
Q. Special Function Generator
:
= “9-Zero“
Starts “Velocity mode” with reference

Q. Special Function Generator
:
unequal “9-Zero“
Starts with reference value from source from

6e Control word =
0x005F
Start Velocity mode with actual speed – a
ramping process is cancelled.
Status word =
0xnn37 Disable voltage
6f Control word =
0x004F
1299
Q. Special Function Generator
:
= “9-Zero“
Starts “Velocity mode” with actual speed
– a running ramp is interrupted.
