b. For full speed tachometer generator output larger than 200 volts, an external resistor (R
E
) is
required in series with tachometer generator connection to terminal B2. The suggested
values for R6 and R7 are:
R6 = 120 k
W
R7 = 68 k
W
R
E
= (Tachometer Generator Volts – 200) k
W
5
The external resistor must be large enough to dissipate the power, P
RE
, determined below.
P
RE
= (Tachometer Generator Volts – 200) x 5 milliwatts
c. The controller accepts only a DC signal as tachometer generator feedback. Accordingly,
motors with AC tachmometer generators require a full-wave diode bridges to rectify the AC
tachometer generator voltage output into DC.
d. Fine tuning is performed within the software (refer to the Calibrate Speed Feedback section
in Chapter 5).
3. Armature voltage feedback calibration
R8 + R9 = (Armature Voltage – 100) k
W
10
The minimum allowable armature voltage is 100V with R8 and R9 having no resistance (0
W
).
NOTE. If necessary, refine the calibration by adjusting SETUP PARAMETERS::
CALIBRATION:: ARMATURE V CAL in the MMI.
4. Field current calibration
WARNING!
If using field current control, this resistor must be calibrated correctly; otherwise,
equipment damage and possible injury to personnel may result.
Field current is scaled by resistors R10 and R11 connected in parallel. The combined value of
these resistors is calculated as follows:
R
IF
=
3000
W
(Full Field Current)
NOTE. Calibrate the field current for 0.2 Amps (15 k
W
) when running the drive in field
VOLTAGE CONTROL mode to set a small detection threshold for field loss alarm
sensing.
The combined value of the parallel resistors can be verified by the formula:
R
IF
=
R10 × R11
W
R10 + R11
When using an external stack controller (500 HP and larger rated models), the field current
calibration resistor is calculated with the formula:
R
IF
external stack =
4000
W
Full Field Current
NOTE. If necessary, change SETUP PARAMETERS:: CALIBRATION:: FIELD I CAL
in the MMI.
