Epsilon EP-P Drive and FM-3/4 Module Reference Manual

Cn Tmout

A connection time-out occurs when a FM-3/4DN or any other device on the network does not receive a packet of information

that it was expecting. Connection time-out faults are self-resetting unless ten are received in a row causing a buss-off

condition.

BusOff

This fault occurs when the FM-3/4DN experiences ten connection time-outs in a row. This situation forces a buss-off fault

that is resettable only by cycling logic power on the FM-3/4DN. Buss-offs are generally caused by either DeviceNet wiring

issues, or devices with different baud rate settings residing on the same network.

DupMacID

This fault occurs when the FM-3/4DN's MacID is the same as another MacID on the network. Logic power must be cycled

or an appended program downloaded via PowerTools Pro to the FM-3/4DN.

Drive Over Temp

This fault is for the MDS only and is generated when the drive thermal switch is open due to drive over-temperature. Check

temperature in the enclosure and drive sizing.

Drive Faults

The Active Drive Faults dialog box is automatically displayed whenever a fault occurs. There are two options in this dialog

box: Reset Faults and Ignore Faults.

Resetting Faults

Some drive faults are automatically reset when the fault condition is cleared. Others require drive power to be cycled or the

drive to be “rebooted” to be cleared. If you wish to continue working in the PowerTools Pro software without resetting the

fault, click the Ignore Fault button.

To reset faults that can be reset with the Reset Faults button, simply click the Reset Faults button in the Drive Faults Detected

dialog box or push the Reset button on the front of the drive where the fault occurred.

Viewing Active Drive Faults

To view all active drive faults, select the View Faults command from the Device menu. The dialog box displayed is the same

as Active Drive Faults dialog box described above.

Rebooting the Drive

To reboot the drive, cycle power or select Reboot Drive from the Device menu. This command reboots the drive attached to

the active Configuration Window.

Error Messages

PowerTools Pro will pop-up an error message box to alert the user to any errors it encounters. These message boxes will

describe the error and offer a possible solution.

The terms below appear in a list of common problems you might encounter when working with PowerTools Pro software

along with the error message displayed, the most likely cause and solution.

Assign means to set a value using an equation. For example, x = 2, you are assigning the value of 2 to x.

A Boolean value is a value that represents two states such as On or Off. In the FM-4 there are three variable types that have

Boolean values. They are Boolean Variables, Input Event Variables and Output Event Variables. They all have a Boolean

Value and can be used in equations to assign their Boolean value to another variable or in a conditional test.

In an equation, conditional tests such as (vel > 3.1) become Boolean values.

In FM-4 Programming, unquoted text names are used to represent Boolean constants. Several different names are available.

They all represent the two Boolean states and therefore are interchangeable.

An Expression is a collection of mathematical operands (variables, constants and numbers) and operators( +, -, *, <, >, etc.)

that form a value. The right hand side of an equation (to the right of the =) is an expression.
