The keys include two context- sensitive soft keys, whose current function is indicated by the text shown in the display above each key. The actual values are bit words each containing a sign bit and a bit integer.

The drive receives a stop command and decelerates along a ramp.

Output DIO9 is used as a digital output. Serial number in manufacturing Typically, this parameter does not need to be set.

Assistants 32 The ACS control panel Assistants Assistants are routines that guide you through the essential parameter settings related to a mqnual task, for example application macro selection, entering the motor data, or reference selection. Check for cooling fan failure. Control chain and drive logic diagrams Control chain and drive logic diagrams What this chapter contains The chapter presents the drive control chain and logic.

Parameters Parameters What this chapter contains The chapter describes the parameters, manuak actual signals, of the control program. Page If the fault still occurs, contact your local ABB representative. The embedded fieldbus interface supports the Modbus RTU protocol.

Comments to this Manuals Your Name. If the asc850 speed is below this value longer than the sleep delay During the identification, the drive will identify the characteristics of the motor for optimum motor control.


Additional parameter data Additional parameter data What this chapter contains This chapter lists the parameters with some additional data. True Zero pulse enabled. The motor magnetization modulation is switched off after the brake close delay has passed. The message chain is always started by the master. Drive Logic 1 Control chain and drive logic diagrams Page – Modbus register addresses for the DCU This alarm word is refreshed, ie, when the alarm goes off, the corresponding alarm bit is cleared from the signal.

See the appropriate Hardware Manual for more information on the connection, chaining and termination of the link. The references are bit values consisting of two bit words.

Uploading stores all drive parameters, including up to four user sets, to the Control Panel. Embedded Modbus Eight data bits, odd parity bit, one stop bit. Output Mode Output mode In the Output mode, you can: Parameter errors If you try to backup and restore parameters between different firmware versions, the panel shows you the following parameter error information: It is normal for this alarm to appear during the start-up until the motor data is entered.

System Overview Control through the embedded fieldbus interface System overview The drive can be connected to an external control system through a serial communication link using either a fieldbus adapter or an embedded fieldbus interface. See the motor manufacturer’s recommendations.

Bit Integer Bit Pointers Additional parameter data When a value pointer parameter is connected to an application program, the format is as follows: The chapter describes the contents of the manual.

Assistants When the drive is first powered up, the Start-up Assistant guides you through the setup of the basic parameters. The controller output is the reference for the torque controller.

The resistance of the sensor increases as the motor temperature rises over the sensor reference temperature Tas does the voltage over manuql resistor.


Torque Control Macro 96 Application macros Torque control macro This macro is used in applications in which torque control of the motor is required. Modbus Exception Codes Control through the embedded fieldbus interface Modbus exception codes Table below shows the Modbus exception codes supported by the embedded cas850 interface.

If two encoder interface modules are used, encoder module connected to Slot 2 is used for the temperature supervision. The counter monitors signal Page 40 Trying to load a user set between different firmware versions If you try load a user set between different firmware versions, the panel shows you the following fault information: Programming Via Parameters Note that parameter changes made via the application program override changes made via the DriveStudio PC tool. The ACS control panel 19 Operating instructions Basics of operation You operate the control panel with menus and keys.

Torque reference scaling is defined by the used fieldbus profile e. The state transitions of the source bits are interpreted as follows: The drive controls a pressure boost pump.

The electrical angle equals the mechanical angle multiplied by the number of motor pole pairs.

ABB ACS850 User Manual

Fieldbus adapter communication OK. Page 73 Program manhal 73 X: Any Modbus request resets the timeout counter. Program features 85 Energy saving calculator This feature consists of three functionalities: If the speed reference decreases slower than the set deceleration rate, the motor speed will follow the reference signal.

See Pt JCU x1 above.
