Communicate errors.
►
If it is the first time to use this EtherCAT drive,check whether the version of XML file is
correct. Most masters support scanning slave, it is recommended to create configuration
in scanning way.
►
Some masters require the connection of the network cable according to the ECAT IN
and ECAT OUT.
►
Check whether the PDO synchronization period set by master and slave is the same.
►
The PDO synchronization period (Ethercat communication period) not supported by
EM3E, such as 1.1ms,0.9ms,etc. The common PDO synchronization period is 250us/500us/
1ms/2ms/4ms,etc.
►
Some masters require DIP switches to be set to the same node ID as the configuration
setting.
►
The network cable is faulty or has poor contact,replace the cable. Or check the problem
by swapping it with the network cable on a normally connected node.
►
The EtherCAT drive is faulty,replace the cable. Or check the problem by swapping it
with a normally worked drive.
Drive cannot be enabled
►
Check the status of the drive. Under normal conditions,the PWR green light of the
driver is on for a long time and the ALM red light is off. the L/A green light of the ECAT IN
and ECAT OUT network ports blinks rapidly,the run green light is on for a long time and
the Err red light is off.
►
PDO configuration or PDO mapping error. It needs to configure PDO or PDO mapping
correctly.
►
Check if the value of object 0x6040 is 16#F and if bit0~bit3 of object 0x6041 is 0111.
►
Check the master for warnings or errors. Clear the master station alarm or warning.
►
If the master station shows enable complete,but the motor is not enabled. Check
whether the motor wire is connected wrongly or disconnected. Or check if the output
current of drive is set correctly.
Alarm when send instruction to slave
►
Check the drive for alarms. Check if the drive ALM red light and ERR red light are
flashing,if there is an alarm,check the drive instruction manual and locate the problem
according to the alarm instructions.
►
The operation mode is not correct. Check if object 0x6060 is 8 (CSP mode).
►
PDO configuration exception. Some masters need to check if the slave's object 0x6061
returns the correct value. If 0x6061 is not configured,the slave may not work or the
master may alarm.
►
The limit switch is activated. Check that the limit switch input is the same as the logic
set by the master. Is the polarity of the slave input port the same as the limit switch used.
The limit switch is not damaged. Whether the wiring between the limit switch and the
slave is correct. The bit bit of object 0x60FD is mapped incorrectly with the master.
