Remote Fieldbus control enabled.

Critical speeds A Critical speeds function is available for applications where it is necessary to avoid certain motor speeds or speed ranges because of, for example, mechanical Parameters Parameters What this chapter contains The chapter describes the parameters, including actual signals, of the mznual program.

Page 6 How to select a parameter and change its value For parameter descriptions, see chapter Parameters on page Programmable Protection Functions The drive monitors the status of the Safe torque off input.

Drive status RO1 status Time The parameter is a bit word with each bit corresponding to a function. Can be reset by entering 0 using the DriveStudio PC tool. All parameters can be displayed by setting parameter User-definable Load Curve 66 Program features IR compensation for a scalar controlled drive IR compensation is active only when Motor Voltage the motor control mode is scalar. Basics of the embedded fieldbus interface The cyclic communication between a fieldbus system and the drive consists of bit data words with the ABB Drives profile or DCU bit profile or bit data words with the DCU bit profile.

See section Basics of the embedded fieldbus interface on page Version information of the solution program Basic Operations — Any Mode 22 The ACS control panel Basic operations — Any mode How to start, stop and switch between local and remote control You can start, stop and switch between local and remote control in any mode.


Input DIO6 is used as a digital input. Step Action Display The panel shows a list of erroneous parameters.

On the other hand, a standard pulse encoder determines the rotor position when it rotates but the initial position is not known. The diagram below illustrates the nanual of the embedded fieldbus interface. Sequential Control Macro 98 Application macros Sequential control macro The Sequential control macro is suited for speed control applications in which speed reference, multiple constant speeds, and two acceleration and deceleration ramps can be used.

Program features 73 X: Emergency stop can also be activated through fieldbus Page 74 74 Program features Operation time scheme The simplified time scheme below illustrates the operation of the brake control function.

Dcu bit Profile Control through a fieldbus adapter. Timers 76 Program features Timers It is possible to define four different daily or weekly time periods. How to select a parameter and change its value Modbus Exception Codes Control through the embedded fieldbus interface Modbus exception codes Table below shows the Modbus exception codes supported by the embedded fieldbus interface.

Check if communication master is able to communicate. Programming Via Parameters Note that parameter changes made via the application program override changes made via the DriveStudio PC tool.

Motor thermal protection 1 inactive. Master point-to-point messaging is only supported at the master because the response is always sent to node address 0 the master. Control through a fieldbus adapter.

Check that there is no earth fault in motor or motor cables: Application program licensing and protection The drive can be assigned an application licence consisting of an ID and password using the DriveSPC tool. Contents Control locations and operating modes describes the control locations and operation modes of the drive.

Usually can only be monitored but not adjusted; The user is responsible for installing the emergency stop devices amnual all the additional devices needed for the emergency stop to fulfil the required emergency stop category classes.


Monday Time period 3 ends on Monday. Uploading stores all drive parameters, including up to four user acs8500, to the Control Panel. Page Control through a fieldbus adapter System overview The acd850 can be connected to an external control system through a serial communication link using either an embedded fieldbus interface or a fieldbus adapter.

The upper case texts refer to the states which are used in the tables representing the fieldbus Control and Status words. Basics of operation You operate the control panel with menus and keys.

The drive is speed-controlled; the reference signal is connected to analog input AI1.

Safety instructions Follow all safety instructions delivered with the drive. The control panel can be used to control the drive, read status data, and adjust parameters.

Connecting the panel to the drive The control panel connection to ACS drive is shown in the figure below.


Fieldbus equivalents Serial communication data between the fieldbus adapter and the drive is transferred in integer format. The function keeps the internal start command on until the brake is manuxl in spite of the status of the external stop command. Name Value Information Ready Drive is ready to receive start command. See the appropriate Hardware Manual for more information on the connection, chaining and termination of the link. The controller can be used manhal control process variables such as pressure, flow or fluid level.

Eight data bits, odd parity bit, one stop bit.

It also instructs in using the panel in control, monitoring and changing the settings.
