ABB ACS850 Manual

Encoder Support Program features 63 The figure below is a simplified block diagram of the speed controller. Drive-to-drive link Master Follower Follower Follower Only the least significant bits of the drive bit control and manuall words can be accessed.

Name Brake start torq Brake not closed Check for an earth fault in motor or motor cables by measuring the insulation resistances of motor and motor cable. In process PID control, a process reference setpoint is connected to the drive instead of a speed reference. Parameter Backup Parameter Backup The Parameter Backup option is used to export parameters from one drive to another or to make a backup of the drive parameters.

The longer the derivation time, the more the speed controller output is boosted during the change. Without Zero Speed Delay: Product and service inquiries Address any inquiries about the product to your ads850 ABB representative, quoting the type designation and serial number of the unit in question.

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. Reference Edit In the Reference Edit option, you can: Page Page – Setting the drive control parameters Page Page – Basics of the embedded fieldbus interfac Check for cooling fan failure.


Check for obstructions in the air flow.

Assistants 32 The ACS control panel Assistants Assistants are routines that guide you through the essential parameter settings related to a specific task, for example application macro selection, entering the motor data, or reference selection. By pressing ‘print’ button you will print only current page. 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 57 Program features What this chapter contains This chapter describes the features of the control program. The emergency stop signal is to be connected maanual the digital input which is selected as the source for the emergency stop activation par. How To Change The Value Of Value Pointer Parameters How to change the value of value pointer parameters In addition to the parameters ,anual above, there are two kinds of pointer parameters; value pointer parameters and bit pointer parameters.


Drive Logic 1 Control chain and drive logic diagrams Mechanical brake control A mechanical brake can be used for holding the motor and driven machinery at zero speed when the drive is stopped, or not powered. To cas850 able to start or stop the drive by using the control panel, the drive must be in local control. Status line The top line mznual the LCD display shows the basic status information of the drive.


Page 38 Step Action Display The panel shows a list of erroneous parameters. During the delay, the drive knows accurately the rotor position. Page 6 How to select a parameter and change its value On the other hand, a standard pulse encoder determines the rotor position when it rotates but the initial position is not known. Master point-to-point messaging is only supported at the master because the response is always sent to node address 0 the master.

Parameter Backup The ACS control panel 39 Parameter Backup The Parameter Backup option is used to export parameters from one drive to another or to make a backup of the drive parameters. Feedback 2 subtracted from feedback 1. When adjusting a bit pointer parameter on the control panel, CONST is selected in order to fix the maanual to 0 displayed as C.

Parameters In the Parameters option, you can: Check that there is no earth fault in motor or motor cables: When a jogging function is activated, the drive starts and accelerates to the defined jogging speed along the defined jogging acceleration ramp.
