Table 4.1: 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 and speed reference 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.
P0314 – SERIAL WATCHDOG
Range:
0.0 to 999.0s
Default: 0.0
Properties:
CFG
Access groups via HMI:
NET
Description:
It allows programming a time limit for the detection of serial interface communication error. If the frequency
inverter remains without receiving valid telegrams longer than the time programmed in this parameter, it will be
considered that a communication error has occurred, the alarm A128 will be showed on the HMI and the option
programmed in P0313 will be executed.
After being powered up, the frequency inverter starts counting this time from the first received valid telegram.
The value 0.0 disables this function.
P0316 – SERIAL INTERFACE STATUS
Range:
0 = Inactive
Default: -
1 = Active
2 = Watchdog error
Properties:
RO
Access groups via HMI:
NET
Description:
It allows identifying whether the serial communication presents errors.
Table 4.2: P0316 options
Options
Description
0 = Inactive
Not used for CFW701.
1 = Active
Interface RS485 ativa.
2 = Watchdog error
The serial interface is active, but a serial communication error has been
detected - A128 alarm/F228 fault.
