8.2.5 Setting the mode for process data transfer
The process data can be transmitted cyclically (sync−controlled, 86) via CAN1_IN/OUT
or event−controlled/cyclically without sync (
87) via CAN3_IN/OUT.
The configuration is carried out via C0360.

Selection list (Lenze setting printed in bold) Information
0 No response event−controlled/cyclic without sync
1 CAN1_IN/OUT cyclic (sync−controlled)
8.2.6 Setting of boot−up time/cycle time
Boot−up time (C0356/1)
ƒ Delay time (in ms) after the expiration of which the master sends the NMT telegram
for initialising the CAN network after the master has been switched on (mains
switching).
– Only valid if C0352 = 1 (master).
– Normally the Lenze setting (3000 ms) is sufficient.
ƒ In a CAN network without a higher−level host one node (master) must initialise the
CAN network. The master activates the entire network once at a specific instant and
thus starts the process data transfer.
– State change from "Pre−operational" to "Operational".
Cycle time for process output data CAN2_OUT (C0356/2)
Transmission cycle time (in ms) for CAN2_OUT
Cycle time for process output data CAN3_OUT (C0356/3)
Transmission cycle time (in ms) for CAN3_OUT in cyclic operation (without sync)
ƒ Setting "0" = event−controlled data transmission
(The output data will only be sent if they have been changed.)
Activation delay for process output data (C0356/4)
Delay time (in ms) until the first transmission of process data via CAN2/3_OUT
ƒ When the NMT status "Pre−operational" has changed to Operational", the delay
time is started. Only after the delay time has elapsed, the PDO CAN2/3_OUT is
transmitted for the first time.
