7.2.1.6 Controlword in Gear Mode

Table 7.17 shows the structure of the Controlword. Table 7.18 defines the values for the available synchronization modes (bits
5 and 6). Table 7.19 defines the values for bit 9 of the Controlword.

7.2.1.7 Controlword in ISD Inertia Measurement Mode

Table 7.17 shows the structure of the Controlword. A value of 1 in bit 4 starts the inertia measurement procedure. It must
remain high as long as the procedure is running, otherwise it is aborted. Table 7.21 defines the values for bits 4 and 8 of the
Controlword.

7.2.1.8 Controlword in Cyclic Synchronous Position Mode

The operation mode-specific bits and the Halt bit in the Controlword are ignored by the servo drive. The Halt function is
controlled by the control device.
