Impulse control
8.1.1 Impulse control
When using impulse control, the change-over switch is operated by electric impulses. When you press
the control button, the change-over switch is driven to the corresponding position (I, 0, II). The control
impulse must last more than 100ms to take effect. A new command cannot be given until the change-
over switch has reached the position of the previous command. Figure 8.3 shows the operation of the
change-over switch with impulse control.
