8) AUX FUNCTION #1
Sets the steering mode after the feedback pot has reached the final position (it is for
only the two pots steering and the automatic centering options).
- Level 0 = The steering motor is turned on when a travel demand is active.
- Level 1 = The steering motor is alternatively turned off (for 15sec.) and on (for
3sec.) disregarding the travel demand state.
- Level 2 = The steering motor is alternatively turned off (for 15sec.) and on (for
3sec.) but only when a travel demand is active.
The off state is counted starting from the expiration of the antirollback time. It
duration depends on the AUXILIARY TIME setting. So, in reality, the off state
duration is the sum of the AUXILIARY TIME and the fixed 15sec. delay.
10.8 CONFIG MENU: "ADJUSTMENTS" FUNCTIONS LIST
The ADJUSTMENT functions list is common for both tacho-generator and tacho-
generator plus automatic centering model.
1) ADJUSTMENT #1
This adjustment supports the acquisition of the stator motor resistance and of the
current amplifiers gain (factory adjusted). When Level=1 is set, a stator resistance
acquisition procedure is enabled. The stator resistance is used for the flux
compensation when the COMPENSATION parameter is Level=2 (see 10.4.4).
When Level=2 is set both stator resistance and current gain amplifiers acquisition
procedure is enabled. As soon as this adjustment is turned to a Level different from
0 a DATA ACQUISITION alarm will immediately occurs.
2) SET CURRENT
After the ADJUSTMENT #1 is changed from 0, the operator should connect a DC
ammeter in series with the motor phase U or W. Next push the N° 5 (right side top)
button on the hand set until the motor current is increased to a DC current level
equal to the half Imax value. Then Roll back to ADJUSTMENT #1 and turn to 0 the
selected level. Then execute a save operation pushing OUT and ENTER button.
After switching the key off and on the SW will acquire the parameter (stator
resistance or gains) you want.
Pay attention. The current amplifier gains are factory adjusted while the
stator resistance must be adjusted by the user.
3) ADJUSTMENT #2
Provides the mOhms stator resistance value. It can be acquired (as above
explained) or hand adjusted in 5mOhms step pushing the right side buttons. The
stator resistance value is used for stator resistance drop compensation when
COMPENSATION parameter is level 2. The motor resistance can be measured
between two motor connections. This measured value can be replayed in the hand
set "Adjustment #2" by rolling up or down the right side buttons.
4) ADJUSTMENT #3
Provides the first phase current gain: it can be acquired or hand adjusted pushing
the right side buttons (factory adjusted).
