Precondition for the cyclic synchronised velocity mode
The following conditions must be fulfilled for the cyclic synchronised velocity mode:
–
Modes of operation display (0x6061) = 9
– Statusword (0x6061) = XX0X XX1X X011 0111

Monitoring
Object 0x6041: Statusword
The following statuses of cyclic synchronised velocity mode can be monitored with the object:
–
Bit 12: drive follows the command value (Drive follows the command value)
Bit
1)
Description
12
Drive follows the command value (Drive follows the command value)
0 Drive does not follow the command value for internal reasons (e. g. because a safety
function is active)
1 Drive is in Operation enabled status and follows the command value.
1) Signal status: 0 = low; 1 = high

4.1.8 Cyclic synchronised force/torque mode (CST)
4.1.8.1 Function
The cyclic synchronised force/torque mode enables command values to be pre-set for the device in a
fixed time grid using the drive profile (SYNC interval). The import of the command values is synchron-
ised with the synchronisation signal of the higher-order controller. The synchronisation signal is gen-
erally slower by a whole number than the cycle of the closed-loop controller. The synchronisation time
is generally set by the higher-order PLC (synchronisation time 1 … 20 ms, step 1 ms,
è
Px.1051). The
integrated fine interpolator therefore calculates intermediate support points and derivations from the
setpoint quantity for the closed-loop controller (interpolation).
