Reference control [214]
To control the speed of the motor, the AC drive needs a
reference signal. This reference signal can be controlled by a
remote source from the installation, the keyboard of the
AC drive, or via communication (RS-485, Fieldbus, or
Wireless interfaces). Select the required reference control for
the application in this menu
.
Run/Stop Control [215]
This function is used to select the source for run and stop
commands. This is described on page 132.
Start/stop via analogue signals can be achieved by using
function “Stp<MinSpd [342]”.
Reset Control [216]
When the AC drive is stopped due to a failure, a reset
command is required to make it possible to restart the AC
drive. Use this function to select the source of the reset
signal.
