To be used to have access to special memory address.
NOTE: only Zapi technicians should change this value
9.4.5 Main menu “TESTER” functions list
The TESTER functions are a real time feedback measurements of the state of
the controller/motor/command devices. It is possible to know the state (active /
off) of the digital I/Os, the voltage value of the analog inputs and the state of the
main variables used in the motor and hydraulics control. Enter the home page in
the hand-set display and roll for the TESTER item.
1) BATTERY VOLTAGE
Voltage value with 1 decimal digit. Battery voltage value measured at the key
on.
2) MOTOR VOLTAGE
Percentage value. It is the voltage generated by the inverter expressed in per
cent of the actual battery voltage. 100% means the sine wave width is close
to the actual battery voltage; 0% means the sine wave width is null.
3) VOLTAGE BOOSTER
Percentage value. It is the booster contribute to the voltage really supplied to
the motor expressed in per cent of the actual battery voltage. (Note: when
DC_LINK COMPENSATION is set ON, the VOLTAGE BOOSTER reading
will not match perfectly the booster setting because this latest one is
calculated respect to the nominal battery voltage; VOLTAGE BOOSTER is
expressed respect to the actual battery voltage).
4) FREQUENCY
Hz value. This is the frequency of the sine waves the inverter is supplying.
5) ENCODER
Hz value. This is the speed of the motor measured with the encoder and
expressed in the same unit of the FREQUENCY reading.
6) SLIP VALUE
Hz value. This is the slip between the frequency and the speed of the motor
(SLIP VALUE = FREQUENCY-ENCODER).
7) CURRENT RMS
Ampere value. Root Mean Square value of the line current in the motor.
8) BATTERY CHARGE
Percentage value. It supplies the residual charge of the battery as a
percentage of the full charge level.
9) TEMPERATURE
°C value. This is the temperature of the inverter base plate. This temperature
is used for the HIGH TEMPERATURE alarm detection.
10) MOTOR TEMPERATURE
°C value. This is the temperature of the motor windings picked up with an
