„
After detecting a start control through the start control bit of the control word (or system marker),
transition of the signal (0
→
1) by the rising edge, the Control Unit (UC), according to the operation
mode (P202), enables the digital output(s), driving the motor
„
The motor remains driven, while the start control bit of the control word (or system marker) is on
level 1 (active); if a transition occurs (1
→ 0), a stop control will be set
Impulsive (pushbutton)

NOTE!
The “Reset” button in the monitoring dialog box “control/signals” works always, regardless of the
P229, P232 or P601 programming.
NOTE!
The user must select different command options at P229 and P232. If local and Remote commands
are selected as digital inputs (Ix), then the Control Unit (UC) signalizes it through the status led and
through the HMI E0025 error message.
If the user selects Local or Remote commands using the HMI, P229 or P232 = 1, then the action for an HMI
communication error can be selected through the parameter P311.
P311 – Action for HMI Communication Error
Adjustable
Range:
0 = It Only Indicates Fault
1 = It Turns the Motor Off Factory
Setting:
0
Proprieties: Sys, rw
Description:
This parameter allows selecting which action must be executed by the relay in the event of HMI communication
error detection.
Table 5.2: Parameter P311 options
Options Description
0 = it only indicates fault
It only indicates a fault; it does not turn the motor off. If the communication is reestablished and
the relay is not in Trip or error status, the indication is automatically removed from the display. If the
relay is in Trip or error status, then it is necessary to execute the error reset to remove the indication
1 = It turns the motor off
It turns the motor off, for the operation modes where this command exists. It is necessary to
execute the error reset to remove the indication.
NOTE!
If the HMI is not communicating with the Control Unit (UC), the Control Unit signalizes this condition
through the status led and through the HMI E0031 message. The error code E0031 is only stored in
the UC if either P229 or P232 = 1. When the Local or Remote commands are not being executed by
the HMI (P229 or P232 ≠ 1), then E0031 is only presented on the HMI, it is not stored in the UC, and
the error message is removed as soon as the communication is reestablished.
