(Default Digital input 27): Coasting stop, inverted input (NC). The adjustable frequency drive leaves
the motor in free mode. Logic '0' => coasting stop.
Reset and coasting stop Inverted input (NC). Leaves the motor in free mode and resets the adjust-
able frequency drive. Logic '0' => coasting stop and reset.
Inverted input (NC). Generates a stop in accordance with the quick-stop ramp time set in

. When motor stops, the shaft is in free mode. Logic '0' => quick
stop.
Inverted input for DC braking (NC). Stops motor by energizing it with a DC current for a certain time

Stop Inverted function. Generates a stop function when the selected terminal goes from logical level
'1' to '0'. The stop is performed according to the selected ramp time (par. 3-42

Ramp 2 Ramp-down Time
, par. 3-52
Ramp-down Time
).
NOTE!
When the adjustable frequency drive is at the torque limit and has received a
stop command, it may not stop by itself. To ensure that the adjustable frequency
drive stops, configure a digital output to
this digital output to a digital input that is configured as coast.
(Default Digital input 18): Select start for a start/stop command. Logic '1' = start, logic '0' = stop.
The motor starts, if a pulse is applied for min. 2 ms. The motor stops when Stop inverse is activated.
(Default Digital input 19). Change the direction of motor shaft rotation. Select Logic '1' to reverse.
The reversing signal only changes the direction of rotation. It does not activate the start function.
Select both directions in par. 4-10
