2.6.2 Field weakening control with setting range
< 1 : 1.5
CAUTION: Not permitted when Chapter 2.5 was quit with EMF control!
15.06 = EMF CON
Field weakening function activated
99.05 = Speed at field weakening point according to motor rating plate
41.19 = ?
reference armature voltage scaled to Supply voltage
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.
Check that field is being weakened.
Do not exceed the maximum motor speed permitted. When an analog tacho is being
used, the display at the CDP 312 panel is not yet necessarily correct.
The motor voltage must not exceed the recommended motor voltage; see
General
notes
at the beginning of this chapter.
If the field is not being properly weakened, or not being weakened at all, perform the
work of section
"Field weakening control with setting range larger than 1 : 1.5”
!
*) 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!
