Parker EME Setting up Compax3192-121102 N04 June 2008 63MN-M 5.6: MN initiator = 1 on the negative sideThe MN initiator can be positioned at any location within the travel range. Thetravel range is then divided into 2 contiguous ranges: one range with deactivatedMN initiator (positive part of the travel range) and one range with activated MNinitiator (negative part of the travel range).When the MN initiator is inactive (signal = 0) the search for the machine referenceis in the negative travel direction.MN-M 5:The 1st motor zero point with MN proximity switch = "0" is used as MN.MN-M 6:The 1st motor zero point with MN initiator = "1" is used as MN.6556121: Motor zero point2: Logic state of the home switchWith direction reversal switchesMachine zero modes with a home switch which is activated in the middle of thetravel range and can be deactivated to both sides.The assignment of the direction reversal switches (see page 74) can bechanged.Function Reversal via Following error thresholdIf no direction reversal switches are available, the reversal of direction can also beperformed during the machine zero run via the function ”direction reversal viaFollowing error threshold"Here the drive runs towards the mechanical limit mounted at the end of the travelrange.When the settable Following error threshold is reached, the drive is braked andchanges the travel direction.Caution!Wrong settings can cause hazard for man and machine.It is therefore essential to respect the following: Choose a low machine zero speed. Set the machine zero acceleration to a high value, so that the drive changesdirection quickly, the value must, however, not be so high that the limit thresholdis already reached by accelerating or decelerating (without mechanical limitation). The mechanical limitation as well as the load drain must be set so that they canabsorb the resulting kinetic energy.With motor zeropoint, withoutdirection reversalswitches
