Programming
P0311 – SERIAL INTERFACE BYTE CONFIGURATION
Range:
0 = 8 data bits, no parity, 1 stop bit
Default: 1
1 = 8 data bits, even parity, 1 stop bit
2 = 8 data bits, odd parity, 1 stop bit
3 = 8 data bits, no parity, 2 stop bits
4 = 8 data bits, even parity, 2 stop bits
5 = 8 data bits, odd parity, 2 stop bits
Properties:
CFG
Description:
It allows programming the number of data bits, parity and stop bits of the serial interface bytes. This
configuration must be identical for all the devices connected to the network.
P0313 – COMMUNICATION ERROR ACTION
Range:
0 = Inactive
Default: 1
1 = Disable via Run/Stop
2 = Disable via General Enable
3 = Change to Local
4 = Change to Local keeping commands and reference
5 = Causes a Fault
Properties:
CFG
Description:
It allows the selection of the action to be executed by the device, if it is controlled via network and a
communication error is detected.
Table 3.1: P0313 options
Options
Description
0 = Inactive
No action is taken and the drive remains in the existing status.
1 = Disable via Run/Stop
A stop command with deceleration ramp is executed and the
motor stops according to the programmed deceleration ramp.
2 = Disable via General Enable
The drive is disabled by removing the General Enabling and the
motor coasts to stop.
3 = Change to Local
The drive commands change to Local.
4 = Change to Local keeping
commands and reference
The drive commands change to Local, but the status of the
enabling and speed reference commands received via network
are kept, providing that the drive has been programmed to use in
Local mode the commands via HMI.
5 = Causes a Fault
Instead of an alarm, the communication error causes a drive fault,
so that a drive fault reset becomes necessary in order to restore
normal operation.
The following events are considered communication errors:
Serial communication (RS485):
A128 alarm/F228 fault: Serial communication timeout
The actions described in this parameter are executed by means of the automatic writing of the selected actions
in the respective bits of the interface control words. Therefore, in order that the commands written in this
parameter be effective, it is necessary that the device be programmed to be controlled via the used network
interface (with exception of option “Causes a Fault”, which blocks the equipment even if it is not controlled by
network). This programming is achieved by means of parameters P0220 to P0228.
