Standard connections for speed control
In speed control mode with default settings, the reference signal is connected to
analog input AI1. The start/stop commands are given through digital input DI1;
running direction is determined by DI2. This macro uses control location EXT1.
Faults are reset through digital input DI3.
DI4 switches between acceleration/deceleration time sets 1 and 2. The acceleration
and deceleration times, as well as ramp shapes, are defined by parameters
23.12…23.19.
DI5 activates constant speed 1.
