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

If using negative values for your OnPosn and OffPosn, the most negative value should go in the OnPosn parameter, and the

least negative value should go in the OffPosn.

If the PLS has a rollover point, and the OnPosn is greater than the OffPosn, the PLS will be active whenever the position

feedback is not between the On and Off positions, and in-active whenever the position feedback is between the two positions.

However, the PLS.#.Status will not turn on until it reaches the OnPosn the first time.All on/off positions are defined in user

units.

Direction

This parameter specifies the direction of motion that a particular PLS output will function. If set to Both, the PLS will activate

regardless of whether the motor (or master motor) is moving in the positive or negative direction. If set to Plus, the PLS will

activate only when the motor is moving in the positive direction. If set to Minus, the PLS will activate only when the motor

is moving in the negative direction.

For example: A flying cutoff or flying shear application may use this feature to activate the PLS to fire the knife only

when the axis is moving in the positive direction.

If accessing this parameter from a network, the following table displays values for this 16-bit inter.

Rotary Enable

This parameter is used to enable the RotaryRolloverPosn for this PLS.

Rollover Point

This parameter is the absolute position of the first repeat position for this PLS. When enabled it causes the PLS to repeat

every time this distance is passed. The repeating range begins at an absolute position of zero and ends at the

RotaryRolloverPosn.

For example, in a rotary application a PLS could be setup with an OnPosn of 90 degrees and an OffPosn of 100 degrees. If

the RotaryRolloverPosn is set to 360 degrees the PLS would come on at 90, go off at 100, go on at 450 (360+90), go off at

460 (360+100), go on at 810 (2*360+90), go off at 820 (2*360+100), and continue repeating every 360 degrees forever.

Setup NVM View

At power-down, parameters can be saved to Non-Volatile Memory (NVM). See the “How Communications Work” section

of the “Operational Overview” chapter for more details. In PowerTools Pro, you can customize which parameters will be

saved in non-volatile memory.
