7 Operation7.1 Operating ModesThe servomotor can be operated in several modes. Theoptions described here are based on the use of a masterrunning under CoDeSys.It is also possible to operate the servo system underCANopen DS301 or with the aid of CANopen DS402.Consult Danfoss for the latter 2 options.The various operating modes are described in more detailbelow.7.1.1 ISD Inertia Measurement ModeThis mode measures the inertia of an axis. It is used tomeasure the inertia of the servomotor and the externalload, and is needed to optimise the control loop settings.The friction effects are eliminated automatically.7.1.2 Speed ModeIn speed mode the servomotors are operated exclusivelyunder speed control. For this, the acceleration, maximumspeed and delay before motion are specified via thesoftware.7.1.3 ISD Curve ModeISD curve mode is an extended cam profile modedeveloped by Danfoss that allows several axes to track amachine parameter along a precisely predefined curvedpath with high accuracy and variable speed.ISD curve mode functionality is stored in the componentlibrary under CoDeSys.For more information, see the component librarydocumentation and the operating instructions for theCurve Editor.7.2 Operating Status IndicatorsThe operating status of the ISD servomotors can bedisplayed using the ISD Toolbox software or CoDeSys.In addition to the status indication on the connection box,the ISD Toolbox software can be used to query the statusof the servomotors. This requires using a laptop computerto establish a connection to the CAN bus network. For thisa CAN dongle is needed, which provides the physicalconnection between the CAN bus network and theservomotors.Use the ISD Toolbox software to display individualservomotors directly in order to obtain information aboutthem.Another option is to use CoDeSys on the master controllerto read out parameters related to the servomotors. Forinformation about this, read the description of CoDeSysprogramming.Operation VLT® ISD 410 Servomotor Operating Instructions26 MG75D102 - VLT® is a registered Danfoss trademark77
