6.2.2 Controlling operating
Overview
Control/checkback signals are required in order to control the axis in the indi-
vidual operating modes.
The operating modes are described in Section 9.2. The control/checkback
signals and their handling are described in Section 9.1.
The user must enter the control signals in the user DB. FC MODE_WR trans-
fers the control signals from the user DB to the FM 354 and transfers the
checkback signals from the FM 354 to the user DB.

Checkback signals:
Single settings (in the user DB starting at address 40) and single commands
(in user DB starting at address 42) are also required in order to control the
FM 354. These are transferred by means of write jobs (system data).
