Make sure that it is safe to continue operation in case of a communication break. Writing to control or reference word resets the timeout counter. Flux braking The drive can provide greater deceleration by raising the level of magnetization in the motor. Displays the drive type for example, ACS Types Of Messaging Drive-to-drive link Types of messaging Each drive on the link has a unique node address allowing point-to-point communication between two drives.

The references are bit words each containing a sign bit and a bit integer.


The longer the derivation time, the more the speed controller output is boosted during the change. Speed Calculation Defines the terminal speed value used in acceleration and the initial speed value used in deceleration see parameter group 22 Speed ref ramp.

The function is useful in applications where a smooth and quick restarting is essential. Program cas850 75 Example The figure below shows a brake control application example. Val pointer Value pointer. Page of Go. Page Control ace850 the embedded fieldbus interface Modern Modbus master devices typically provide a means to access the full range of Modbus holding registers. Page 53 Control locations and operating modes 53 Control locations and operating modes What this chapter contains This chapter describes the control locations and operating modes of the drive.


Output DIO6 is used as a digital output.

The frequency signal connected to DIO1 is scaled acs580 an internal signal How to view last parameter changes and edit parameters Step Action The function is useful in applications with a high break-away torque where direct torque control DTC mode cannot be applied. Fieldbus adapter communication OK. See chapter Control maanual the embedded fieldbus interface on page Parameter errors If you try to backup and restore parameters between different firmware versions, the panel shows you the following parameter error information: Status line The top line of the LCD display shows the basic status information of the drive.

It is also possible to use digital inputs to switch between different user parameter sets. Initially, the panel is in the Output mode, where you can Mot bearing Pre-selectable alarm for the drive run time counter.

The function prevents drive restart i. To be able to start or stop the drive by using the control panel, the drive must be in local control. Enter text from picture: See Pt JCU x1 above. When the total area exceeds the limit set by parameter Check for an earth fault in motor or motor cables by measuring the insulation resistances of motor and motor cable. Page 62 62 Program features The prerequisites for performing the autotune routine are: List Of Tasks 20 The ACS control panel List of tasks The table below lists common tasks, the mode in which you can perform them, abbreviations of the options in the Main menu and the page number where the steps to do the task are described in detail.

Program features 71 Sleep function for process PID control The following example visualizes the operation of mxnual sleep function. Uploading stores all drive parameters, including up to four user sets, to the Control Panel.
