Remedy
After the setting value is set to equal to or less
than "[Pr.8] Speed limit value", turn the PLC
READY signal [Y0] from OFF to ON.
After the setting value is set to equal to or more
than "[Pr.7] Bias speed at start", turn the PLC
READY signal [Y0] from OFF to ON.
Correct the setting value, turn the PLC READY
signal [Y0] from OFF to ON.
Correct the setting value, turn the PLC READY
signal [Y0] from OFF to ON.
Correct the setting value, turn the PLC READY
signal [Y0] from OFF to ON.
Set the station number of the slave station to be
connected to the network to be less than or
equal to the total number of slave stations.
• When a stop error of the CPU module is
detected, check the details of the CPU
module error and take actions.
• Review the communication cycle.
• Check for abnormalities in the surrounding
environment, such as noise, and remove the
cause.
• After taking the above measures, switch the
power on again or reset the CPU module.
Connect a supported driver.
• Review the slave object setting.
• Check the manual of the driver.
Set the station numbers of the slave stations to
connect to the network in ascending order.
Review the transient transmission time. It is
obtained by the following equation.
(Transient transmission time = Communication
period interval setting - Cyclic transmission time
- System reservation time)
• Shorten the communication cycle.
• Check for abnormalities in the surrounding
environment, such as noise, and remove the
cause.
• Connect only to the stations for which the
network configuration has been set.
