Magtrol Model DSP7000 Dynamometer ControllerChapter 7 – Computer Controlled Operation
OPERATION
EXAMPLE
If a motor is running at 1725 rpm clockwise, with the dynamometer loading the motor to
22.6 oz.in., the DSP7000 will return:
S 1725T22.60R
By manipulating the string, the speed-torque and shaft direction (if required) can be extracted.
Then separate numerical variables can be assigned to them for data processing.
7.2.2 ouTpuT Binary CoMManD (oB)
A list of paramaters can be created using the COB (Configure Output Binary) Table. The list can be
retrieved at a rate of 488 samples per second. Up to 35 paramaters can be added to the list making
it possible to read 488 × 35 = 17080 parameters per second all synchronized in time.
1. The user used the COB table to configure the DSP7000 to package the required data.
Minimum command is the return of the timers (COB,0,1).
