198 CONFIGURA TION
13.13.3 DRIVE PERSONALITY / Maximum current response PIN 678
The PL/X is capable of providing a super fast current response. When enabled, the current loop algorithim is
internally adjusted to provide a very rapid response, with no dead band when switching bridges. When
enabled, it is important that the speed and current control terms are carefully set for optimum performance
otherwise current overshoots or noisy feedback signals may cause instability. When disabled, the current
response is similar to a standard performance DC controller, w hich in most cases is completely acceptable,
also the PL/X is more tolerant of poor feedback/control term settings.
13.13.4 DRIVE PERSON ALITY / Armature current burden resistance PIN 680
The burden resistors are on the lower edge of the power board to the right of the 8 w ay terminal block.
(R100//R101 1 00 % parallel back pair) or (R102//R1 03 50% parallel front pair) selected by jumper.
Formula. Combined value of BURDEN OHMS = 2000/max model amps. For PL/X 5 - 145.
Combined value of BURDEN OHMS = 4000/max model amps. For PL/X 185 - 225.
Note. After parameter 680)Iarm BURDEN OHMS has been altered, it will only apply after the following steps:-
1) Save the ne w value using the PARA METER S A V E function.
2) Turn the unit control supply off then back on again.
3) Adjust- 2)RA TED ARM A MPS parameter in the C ALIBRA TION menu, first to its maximum setting
(100%), and then to its minimum setting (33 %), (Note that the values are 100 % Amps, 33% Amps,
of new ratings with changed burden). Finally return it to the desired value for your motor.
4) Save the ne w desi red 2)RATED ARM A MPS parameter with another PARA METER SA VE.

With jumper in this 100 % position
R100 and R101 are in parallel with
R104. Result = 100% current.
With jumper parked on one pin, only
R104. is connected
Result = small motor current.
330R gives 6A (5 - 50 models).
82R gives 24 A (65 - 1 45 models).
150R gives 2 4 A (185- 26 5 models)
