1) R/W = read and write, R = read only, W = write only
2) Force is controlled and evaluated by closed-loop control of the motor current. A torque level or a linear force can be determined from
the level of current measured depending on the mechanism of the drive. The target is set as a percentage of the rated motor current
and may deviate from the actual force on the drive unit. If force levels are set low, the influence of friction in the system on the
running behaviour and the actual force on the drive unit must also be taken into account.
3) This value is transferred to the memory every 15 minutes. After a restart, the value corresponds to the status of the last save process.
Changes to the cycle counter that have started since the last saving process are lost with on restart or power off.
4) This value is transferred to the memory every 15 minutes. After a restart, the value corresponds to the status of the last save process.
Changes that have started since the last saving process are lost with on restart or power off.

Process data
The process data contain all control and status data (e.g. commands, status information) required
to operate the drive system. The process data are cyclically exchanged between IO-Link master and
EMCS-ST.
