- Set the FREQUENCY CREEP starting from 0.3 Hz. The machine should
just move when the drive request is active. Increase the level
accordingly.
- Set speed reduction as required by your specifications (see parameter
HB ON / SR OFF in list SET OPTIONS).
- Set the other performance-related parameters such as RELEASE
BRAKING, INVERSION BRAKING, DECELERATION BRAKING, PEDAL
BRAKING, SPEED LIMIT BRAKING, MAX SPEED FORW, MAX SPEED
BACK.
- Set the parameters related to the behavior on a slope (STOP ON RAMP
and AUXILIARY TIME parameters).
- Test the truck in all operative conditions (with and without load, on flat
and on ramp, etc.).
7.2.2 Set-up additional procedure for AC pump inverter
This section describes the additional set-up procedure for the pump section when
controller is used in Combi configuration.
- MAX SPEED LIFT, 1ST SPEED COARSE, 2ND SPEED COARSE,
3RD SPEED COARSE.
- Set the parameters related to hydraulic steering, 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.
7.2.3 Position Sensor acquisition
Position sensor needs to be acquired because it has an arbitrary shift with
respect to the magnetic-field zero position. Offset, amplitude and angle must be
set before starting a PM for the first time.
Preliminary settings are the same as described above. Plus, an automatic
acquisition procedure embedded in the inverter software is to be activated only
once at commissioning.
Before starting the procedure, be sure that the motor is free to spin, with a
minimum load on the shaft.
- In OPTIONS, select ABS SENS. ACQUIRE.
- Select NO at the request of saving data (otherwise the main coil will be
opened).
- The message ACQUIRING ABS indicates that the acquisition procedure
is ready to start.
- Use the TESTER function to monitor the motor speed for the next steps.
- Activate the TILLER and FW (or BW) microswitches. Motor starts running
in open-loop mode.
- Because of the open-loop mode, it is normal if the reported speed is not
perfectly stable, but value on display must be, in any case, quite fixed.
- If the motor does not spin, it vibrates or speed on display oscillates too
much, stop the acquisition procedure releasing the FW or BW command
(see troubleshooting at the paragraph end).
- The first phase, where motor is spinning at low speed (something like
5 Hz), allows the inverter to acquire signal offset and amplitude for both
channels.
- After the previous steps are completed, rotor is aligned to the magnetic
field origin, and the sin/cos angle is acquired and stored.
