driver resulting in malfunction of the motor. For information on the filter time, refer to description of P1-15 function parameters. Different command input pulse forms have different timing sequence and time parameters. For details, see Table 3-7 and Table 3-8:Table 3-7 Timing sequence table of different command pulses 3.4.6.1 Differential input mode of position command pulse Table 3-8 Pulse input time parameters Upper computer Servo driver For pulse position command, the minimum pulse width is 1 μs and the maximum input frequency is 500 kpps Fig.

Upon input of command pulses, pulse loss occurs. Upon input of a command direction, a reverse command direction is taken.
