and hold the
SET
key and then release it, the system automatically measures the initial angle,
and the LED displays "――――――". When the measuring is completed, the LED displays
"OK".
You need to save the measured values to the EEPROM by using the parameter writing
function of the shortcut menu. Otherwise, after the system is shut down, the calibration status
is restored to the previous status.
Set parameters on the LED:
6.2.5 Low-speed jogging
The test purpose is to check whether the basic functions of the servo system are normal.
1.
Check and prepare for the running.
For the first run of the servo system, you must check whether the hydraulic loop connection
and the servo system electrical connection are correct; whether the values of the oil pump
displacement and working pressure are consistent with those on the nameplate. At the earlier
period, adjust the system so that the oil discharged from the pump goes directly back to the
tank, for example, by setting the overflow pressure of relief valve to the lowest.
2.
Run at low speed with light load.
When the LED displays the E12 status, press and hold the
SET
key and then release it to
enter the jogging mode. Then the LED displays "JOG". You can press the
or
key
to make the motor jog forward or reversely. You can press and hold the
or
key to
make the motor accelerate to the max. forward or reverse jogging speed.

3.
Confirm the working situation.
When you are sure that the motor runs forward, the pump rotates in the same direction as the
arrow on the pump label; the noise and vibration are in the normal range and the pump can
suck oil normally.
Fault
Symptom
Solution
Condition 1
The motor does not rotate,
and the torque is great.
Access the setup menu, and change the
motor rotation direction. Repeat the
operations in section 6.2.4.
Condition 2
When the motor runs
forward, the pump rotates in
the a direction different from
the arrow on the pump label.
Access the setup menu, and change the
motor rotation direction and resolver
direction. Repeat the operations in section
6.2.4.
a)
Discharge air.
After step 2 is performed properly without any exception, run the pump forward to
