2.7Balancing the speed controller, plus fine-balancing the e.m.f. and the current controllers

1701 = 11206

Change between POT1 and POT2 activated.

Extremely reduce the ramp-up time, depending on the system conditions:

1708 = 0,1 s

1709 = 0,1 s

Adjusting the potentiometers for speed controller balancing:

During acceleration/ braking, the drive should reach the current limitation, if necessary increase the value of POT1.

Scaling of 1204 and 1205 ⇒ 20 000 corresponds to 100 % speed.

1204 (POT1) = 10%...20% max. speed

1205 (POT2) = 0

1206 (PERIOD) = Adapt as necessary.

Switch ON power; start drive.

DANGER: System components now energized!

Drive should run at speed values corresponding to POT1 and „0“.

For assessing control quality, the Fig. entitled "Transient response of controller" ( ⇒ section 2.6.3) can be used.

For this purpose, the following parameters at the speed controller must be adapted: 2014 = desired response (behaviour) of controller

2018 = desired response (behaviour) of controller

Only when fine-balancing of the e.m.f. controller is wanted! ((Necessary when work as per section 2.6.3. has been performed)

Only when fine-balancing of the current controller is wanted!

For assessing control quality, the Fig. entitled "Transient response of controller" ( ⇒ section 2.6.3) can be used.

- If fine-balancing of the current controller is wanted, the settings for the software potentiometers can be retained.

The following parameters at the current controller must be adapted: 407 = desired response (behaviour) of controller

408 = desired response (behaviour) of controller

-If fine-balancing of the e.m.f. controller is wanted, potentiometers' settings must be adapted:

1204 (POT1) approx. 10 % smaller than speed at field weakening point 1205 (POT2) ca. 10% greater than speed at field weakening point The following parameters at the e.m.f. controller must be adapted: 1007 = desired response (behaviour) of controller

1008 = desired response (behaviour) of controller.
