data (e.g. digital input, encoder value, etc.)   
 
Outputs in Safe-Op state 
The sync manager watchdog expires when the master application does not provide 
new output process data within the configured watchdog time. In this case the slave 
will automatically go from operational state to ERROR-SAFEOP state and set all the 
outputs in a safe state. Will stop the stepper motor and the motor current will be 
adjusted to 0. 
 

Operational (Op) 

Here both the process data object (PDO) and service data object (SDP) are fully 
enabled. Master sends cyclic output data and read input data. This module supports 
two types of Op modes: Free Run mode and Distributed Clock (DC) mode. 
 
 

3.3

 

Synchronization Modes 

 

ECAT-2094P devices support two different modes 

 

Free Run: The master cycle time and slave cycle time is independent and not 
synchronized. 

 

Distributed Clock (DC): The master cycle time and slave cycle time are synchronized. 

 

3.3.1

 

 

Free Run Mode 

 
The slave operates autonomously according to its cycle and is not synchronized with 
the EtherCAT cycle. 

The master cycle time and the slave cycle time are fully independent 

which means each slave device reads/writes its own process data according to its local time, 
independent of the master’s cycle time.
