12.4.7 Main menu “TESTER” functions list
The TESTER functions are real time feedback measurements of the state of the
controller. It is possible to know the state (active disactive) of the digital I/Os, the
voltage value of the analog inputs and the state of the main variables used in the
motor. Enter the headline in the hand-set display and roll for the TESTER item.
1) STEPPER MOTOR
Voltage value with 2 decimal digit. Measurement of the stepper motor speed
with sign in the range 0 to ±5 Vdc.
2) SET POINT POT
Voltage value with 2 decimal digit. Measurement of the potentiometer connected
to CNA#9 (CPOC1). Switch DEBUG OUTPUT to level 13 to get CNA#8
(CPOC2) on this reading (see 12.4.6.4).
3) FEEDBACK POT
(feedback pot version only). Voltage value with 2 decimal digits. Measurement
of the feedback potentiometer connected to CNB#6 (CPOT).
4) FEEDBACK SECTOR
(toggle switches version only). Voltage value with 2 decimal digits. It supplies
real time the information of the sector (quadrant) detected through the toggle
switches. It assume the following value:
3.13 V in the sector from 0 to +90 degrees.
4.39 V in the sector from +90 to +180 degrees.
0.62 V in the sector from -180 to -90 degrees.
1.88 V in the sector from -90 to 0 degrees.
5) FEEDBACK ENC
Voltage value with 2 decimal digit. Measurement (scaled in the range 0 to 5
Vdc) of the position of the feedback encoder connected to CNB#7 and CNB#8.
6) TEMPERATURE
Degrees. Temperature of the controller base plate.
7) MOTOR TEMPERATURE
Degrees. Temperature of the motor windings measured with the thermal sensor
inside the motor and connected to CNB#3.
8) FREQUENCY
Hertz value with 2 decimal digit. This is the frequency applied to the steering
motor.
9) SAT. FREQ HZ
Hertz value with 2 decimal digit. This is a real time magnetic flux measurement:
Vbattery/ SAT. FREQ HZ provides real time the linked flux in the motor. The flux
in the motor is modulated from 75% to 100% of the maximum flux.
The maximum flux is Vbattery/SET SAT FREQ.
The minimum flux is Vbattery/(1.33*SET SAT FREQ). When the motor is
loaded, SAT. FREQ HZ is equal to SET SAT FREQ; when the motor is
lightened the flux reduces and SAT. FREQ HZ increases up to 1.33*SET SAT
FREQ.
