What this chapter contains
This chapter instructs in setting the drive parameters and in checking the system.
Parameter settings
The table below instructs in parameter settings for a drive with ACS800 Standard
Control Program starting a four-pole motor (50 Hz). With these settings, the trim
control can affect ±20 rpm to final speed reference (1% of the defined maximum
speed limit). Here, the panel will be used as the external control signal interface.
That is the recommended practise at the start-up. Change later to I/O or fieldbus
control if needed. However note that analogue input AI1 and digital input DI5 are
reserved for the synchronization application.
Before starting, ensure that the contactor control circuit connection at terminal J2 of
the RSYC unit is disconnected.
For the use of control panel, see ACS800 Standard Control Program 7.x Firmware
Manual (3AFE64527592 [English]).
Setting
Selecting control location and signal sources
Select external control location EXT2
into use.
Define control panel for source of
control commands for external control
location EXT2.
Define control panel for source of
speed reference for external control
location EXT2.
Fix rotation direction of motor to
forward.
Deactivate constant speed selections.
Set digital input DI5 to source for run
enable signal.
Define maximum and minimum limits
for the motor speed.
Define the stop mode for the run
enable function.
Settings of PID controller used by Trim function, Parameter group 40
Activate error value inversion.
Activate ACT1 for PID controller.

Additional information
11.02 = EXT2
Trim function can be used only with % reference
(REF2). REF2 can be given from various
interfaces. Here, control panel (KEYPAD) will be

See section
20.01 = 0.00 rpm
Maximum speed must be higher than motor
nominal speed. 2000 is suitable value for a 4-

The drive will cut off output voltage immediately
after run enable is switched off.
