 Details about Pulse String Input Mode
Command frequency is determined by the frequency of the pulse string input.
The sign of the command frequency is determined in the following way.
a) Mode 0: [CA-91]=00 90° phase difference pulse string
b) Mode 1: [CA-91]=01 forward and reverse rotation co pulse string
