13. Now adjust the SlipGain parameter to provide maximum torque at low
speeds. Note: e present SlipGain value was determined by the auto-char-
acterization procedure, and is not the default value.
Motor » Control Algorithms » 0-ACIM » Characterization Tests » SlipGain
Set Max Speed to a fairly low speed (but high enough to be able to lift
a load on the forks), typically 800 rpm. e Max Speed setting must be
below the motor base speed, which is measured in the next step.
Put a very heavy load on the forks, preferable a max load.
Apply full throttle, and vary the SlipGain until the motor current is mini-
mized (Monitor  Controller  Current (RMS)). If the vehicle has a multistage
mast, work in the rst stage only so that the load is consistent.
14. Run the FW Base Speed test.
Set Max Speed to the maximum desired pump speed.
Set
FW Base Speed = 6000 rpm. e test should be run with batteries
that have a reasonable charge.
Motor » Control Algorithms » 0-ACIM » Field Weakening Control » FW Base Speed
Set the Accel Rates to be very fast, so that you’ll be accelerating at full
current during the test.
Because the pump can accelerate past FW Base Speed quickly, it is
necessary to pre-ux the motor current prior to running this test to get an
accurate measure of base speed. To pre-ux the motor, note the displayed
Test Current value (Monitor  Controller  Motor Tuning  Test Field Current)
and enter this value for Min Field Current.
Motor » Control Algorithms » 0-ACIM » Field Weakening Control » Min Field Current
e controller is now running current with no throttle, so continue
this test without delay to prevent motor and controller heating.
From a stop, quickly apply full throttle to accelerate to a high speed.
After the motor settles at a speed for a moment, release the throttle to stop.
Note the value of the Base Speed Captured (Monitor  Controller  Motor
Tuning  Base Speed Captured), and enter this value for the FW Base Speed
setting.
e test restarts each time the vehicle comes to a stop and the throttle
is released, so be sure to note the value before reapplying the throttle.
When nished, be sure to set the Min Field Current = 0 to cancel
the pre-ux current.
