• Phase difference detector
Detects the phase difference between two torque signals to oscillates a pulse train corresponding to phase
variation.
• Torque counters
Since the TS-3200A has a short sampling time, it is provided with two torque counters: one counts the
pulse train which is proportional to the phase difference and the other counts the pulse train with a fixed
phase difference (360 degrees) to obtain T1 and T2, respectively.
• Rotational counters
Like the torque counter unit, the TS-3200A is provided with two rotational counters: one counts the
number of input signal pulses, N, and the other counts the total value of the integrated period, T.
Although the sampling time synchronizes with the torque counter units, the count times of the two
counters are not the same because of different input signals.
• Memory unit
This unit consists of nonvolatile memory which memorizes various parameters (including N-0
compensation) specified by key entry.
• Data processing unit
This unit consists mainly of a microprocessor to perform high-speed operation, time constant operation,
sequence control, and interface control.
It processes high-speed operation for each sampling time (4ms/optionally 1ms) based on the expression
below. The unit counts the pulse train which is proportional to the phase difference and the pulse train
with a fixed phase difference (360 degrees) to obtain T1 and T2, respectively.
