Application macros What this chapter contains Programming Via Parameters Note that parameter changes made via the application program override changes made via the DriveStudio PC tool. How to select a parameter and change its value Enter text from picture: How To Change The Value Qcs850 Value Pointer Parameters How to change the value of value pointer parameters In addition to the parameters shown above, there are two kinds of pointer parameters; value pointer parameters and bit pointer parameters.

Don’t show me this message again. Only the least significant bits of the drive bit Control and Status words can be accessed. Page Control chain and drive logic diagrams As a consequence, the process PID controller decreases the motor speed.


Control through a fieldbus adapter. Lowering the speed reduces the CPU load.


Control locations and operating modes describes the control locations and operation modes of the drive. Editing is allowed only in the LOC state, the option always edits the local reference value. Drive-to-drive connection can be enabled only if the embedded fieldbus interface is disabled parameter Output DIO6 is used as a digital output.

Miscellaneous 86 Program features Amplitude ranges parameters Safety instructions Follow all safety instructions delivered with the drive. When IR compensation is activated, the drive IR Compensation gives an extra voltage boost to the motor at low speeds.

ABB ACS850 Manual

Comments to this Manuals Your Name. Basics of operation You operate the control panel with menus and keys. Page DriveStudio PC tool. The drive controls a pressure boost pump. What This Chapter Contains The chapter describes the contents of the manual. 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.

Ensure proper 0x model has exceeded alarm motor cooling: The resistance of the sensor increases as the motor temperature rises over the sensor reference temperature Tas does the voltage over the resistor.


The drive monitors the status of the Safe torque off input. If the run enable signal is switched off, the drive will not start, or coasts to stop if running.

Greater of the two feedback sources used. Ext2 act External control location EXT2 is active. The sign of the reference determines the running direction. The drive is stopped using the active deceleration time.

The overvoltage fault level is set to V.

Only the least significant bits of the drive bit control and status words can be accessed. Control through a fieldbus adapter Control through a fieldbus adapter What this chapter contains The chapter describes how the manul can be controlled by external devices over a communication network fieldbus through an optional fieldbus adapter module. When adjusting a bit pointer parameter on the control panel, CONST is selected in order to fix the value to 0 displayed as C.
