• Field circuit
The TPD32-EV regulation card is shipped with the field current feedback resistor dipswitches S14 calibrated
for the maximum rating of the field package capacity for each size TPD32-EV .
Compare the actual motor field data to the maximum rating of the field package of the TPD32-EV model sup
-
plied (see table 2.3.3.1), and to the field calibration dipswitch S14, as noted below.
- For fixed field current operation, if the actual motor (base) field current ≤ 10% of the maximum rating of
the field package it is required to calibrate the field current feedback scaling using dipswitch S14.
- For weak field operation, also referred as “CEMF field control” or “crossover field control”, if the top base
speed Motor nom flux ≤ 10% of the maximum rating of the field package it is required to calibrate the
field current feedback scaling using dipswitch S14.
Calibration to the exact field current setting is not required, as long as the above conditions are met.
Calibration is not required if the field control is provided by a separate field converter.
In order to obtain a current setting value different from those stated in the table, use the following formulas to
calculate the resistance to be used between the terminals LA and LB on the regulation card. In this case all the
switches have to be set to zero (OFF).
1) For sizes TPD32-EV-.../...-20-..-A (17-NA-..-A) ... up to TPD32-EV-.../...-1050-..-C (850-NA-..-C) :
Resistance = 1667 / field current (A).
