9.1.11 Internal Velocity Command
Combining external input signals (3 bits), this command is capable of selecting speed (parameter) and
direction.
The CN1 35 and 36 pins are used for selecting the speed, and 34 pin is used for selecting the revolution
direction.
Note 1: This function is enabled when parameter Func3 bits3, 2, 1 and 0 are all set at "1010" in the velocity
control mode. In this case, the polarity reverse function of the external analog velocity command,
the velocity command scale and the velocity command are all disabled.
Note 2: If there is a lag between input timing to the CN1 35 and 36 pins, another speed can be selected.
Switching of the signal must take place simultaneously.
Note 3: Note that there is a 12 msec maximum delay from changing the input signal to completion of
control mode switching.
