- In HARDWARE SETTING increase the ABS.SENS. ACQ.ID parameter (the
motor current used for the open-loop phase) so to have more torque and
perhaps solve some friction problems (ID RMS MAX must be set
congruently).
- If increasing ABS.SENS. ACQ.ID is not enough, increase the
ABS.SENS.A.KTETA parameter. It manages the speed in the open-loop
phase and in some situations faster speed can help to achieve a more even
rotation.
4 Offset angle can also be manually refined using the MAN.OFFSET ANGLE
parameter. However, sensor voltage range must be first acquired using the
automatic procedure.
7.5 Set-up procedure for pump inverter
This section describes the basic set-up procedure for the ACE3 inverter in pump
configuration. If you need to replicate the same set of settings on different
controllers, use the SAVE and RESTORE sequence (see chapter 8); otherwise go
down the following sequence.
- In ADJUSTMENT, set BATTERY VOLTAGE according to your set-up (see
paragraph 7.2.3).
- Check the wiring and that all commands are functioning. Use the TESTER
function to have real-time feedback about their state.
- Perform the accelerator acquisition using the PROGRAM VACC procedure
(see paragraph 8.1).
- Set the maximum current for lift and lowering in MAX. CURRENT TRA and
MAX. CURRENT BRK (see paragraph 7.2.1).
- Set the motor-related parameters. It is suggested to discuss them with Zapi
technicians.
- Set SET MOT.TEMPERAT according to the type of the motor thermal
sensor adopted.
- Set the acceleration delay (ACCEL MODULATION and ACCEL DELAY
parameters). Test the behavior in both directions.
- Set the FREQUENCY CREEP starting from 0.3 Hz. The pump should just
run when the request is active. Increase the level accordingly.
- Set SPEED REDUCTION as required by your specifications.
- Set the other performance-related parameters such as MAX SPEED LIFT,
1ST SPEED COARSE, 2ND SPEED COARSE, 3RD SPEED COARSE.
- Set hydraulic-steering-related parameters, such as HYD SPEED FINE and
HYDRO TIME.
- Test the pump in all operative conditions (with and without load, etc.).
At the end of your modifications, re-cycle the key switch to make them effective.
