Table 8: Control Word Bits in PROFIdrive Standard Telegram 1
(continued)
Bit number Name Description
3 Operation 1: Enable operation.
0: Disable operation.
4 Ramp generator 1: Enable ramp generator (RFG).
0: Reset ramp generator. Output of the RFG is set to 0. The drive deceler-
ates along the current limit or along the voltage limit of the DC link.
5 Freeze 1: Unfreeze ramp generator.
0: Freeze ramp generator. Freezes the present output frequency (in Hz).
6 Enable setpoint 1: Enable setpoint.
0: Disable setpoint.
7 Fault acknowledge 0
⇒
1: Acknowledge faults.
Acknowledging is edge-triggered, when changing from logic 0 to logic
1.
0: No function.
8 Jog 1 1: Jog 1 on.
0: Jog 1 off.
Operation is enabled, drive is at standstill, and STW1 bit 4, 5, 6: 0. The
drive runs up along the ramp to jogging setpoint 1.
9 Jog 2 1: Jog 2 on.
0: Jog 2 off.
Operation is enabled, drive is at standstill, and STW1 bit 4, 5, 6: 0. The
drive runs up along the ramp to jogging setpoint 2.
10 Control by PLC 1: Uses process data (control by PLC).
0: Ignores the current process data. This is linked to a submodule where
the CTW is present. If signals are to be covered, the CTW/STW profile (for
example, the iC Speed Profile) must be part of the signals list.

These bits enable the mapping of application functionality of the drive
to the control word. Mapping is done through parameters. For more in-
formation, refer to the
