The TC. command is only used for reading the time constant, and reports the current
setting in seconds. Hence if a TC 11 command were sent, TC would report 11 and
TC. would report 1.0E-01, i.e. 0.1 s or 100 ms.
SYNC [n] Synchronous time constant control
At reference frequencies below 10 Hz, if the synchronous time constant is enabled,
then the actual time constant of the output filters is not generally the selected value T
but rather a value equal to an integer number of reference cycles. If T is greater than
1 cycle, the time constant is between T/2 and T. The parameter n has the following
significance:
n Effect
0 Synchronous time constant disabled
1 Synchronous time constant enabled
