10.4.4 Zapi menu “SPECIAL ADJUSTMENTS” functions list
4
Note: the below set-up description is for skilled persons only: if you aren’t, please
keep your hands off. To enter this Zapi hidden menu a special procedure is
required. Ask for this procedure, directly to a Zapi technician.
In the SPECIAL ADJUSTMENTS functions list, there are factory adjusted
parameters only.
1) ADJUSTMENT
#01
(Factory adjusted). % value. This is the Gain of the first Current Sensing
Amplifier of traction motor.
NOTE: only Zapi technicians should change this value
2) ADJUSTMENT#02
(Factory adjusted). % value. This is the Gain of the second Current Sensing
Amplifier of traction motor.
NOTE: only Zapi technicians should change this value
3) SET
CURRENT
(Factory adjusted). This is the traction motor maximum current.
4) SET
TEMPERATURE
Set the temperature offset to have the correct value reading. This is a fine
calibration of the controller temperature sensor.
5) ADJUSTMENT#03
(Factory adjusted). % value. This is the gain of the Current Sensing Amplifier
of pump motor.
6) SET CURRENT PUMP
(Factory adjusted). This is the pump motor maximum current.
7) HIGH
ADDRESS
To be used to have access to special memory address.
NOTE: only Zapi technicians should change this value
8) DITHER
AMPLITUDE
It is the dither signal amplitude. The dither signal is a square wave which is
overlapped to the proportional valves set point. In this way the proportional
valves response to set point variations is optimized. This parameter is a
percentage of the valves maximum current. It can be adjusted in the 0% to
20.3% by nine levels. Setting the parameter to 0% means the dither isn’t
used.
9) DITHER
FREQUENCY
It is the dither signal frequency. It can be used one of three:
-
0: the dither signal frequency is 62.5 Hz
-
1: the dither signal frequency is 83 Hz
-
2: the dither signal frequency is 125 Hz.
