Balancing The Field Supply Unit And The Emf Controller - ABB DCS 600 MultiDrive Operating Instructions Manual

Chapter 2 - Start-Up Instructions

2.6 Balancing the field supply unit and the EMF controller

When matching the field supply unit to the system conditions, differences in the proce-
dures must be taken into account; these different procedures result from the operating
mode used. Only the work of that section has to be performed which deals with
the operating mode actually used in your system!
Constant field current control
Field weakening control with setting range smaller than 1 : 1.5
Field weakening control with setting range larger than 1 : 1.5
2.6.1 Constant field current control
Switch ON power.
DANGER: System components now energized!
Start drive.
Measure motor voltage with the ARM_VOLT_ACT signal, Parameter 1.14 *).
Increase speed reference value in LOCAL mode slowly while observing the motor
voltage.
The motor voltage must not exceed the recommended motor voltage; see General
notes at the beginning of this chapter.
*) This Parameter must be transmitted from the SDCS-CON-2 board to the SDCS-AMC-DC board!
Measure speed with manual tacho;
check rated speed when an analog tacho is being used;
if necessary, correct with Potentiometer R2716 [on SDCS-CON-2 board] or
R9 [on PS5311 board].
Stop the drive and switch OFF power!
