Selection description
Inverted input (NC). Generates a stop in accordance with the
quick stop ramp time set in P 5.7.7 Quick Stop Ramp Time. When
the motor stops, the shaft is in free mode. Logic 0⇒Quick-stop.
Note: When the frequency converter is at the torque limit and
has received a stop command, it may not stop by itself. To ensure
that the frequency converter stops, configure a digital output to
[27] Torque limit and stop and connect this digital output to a
digital input that is configured as coast.
Inverted input for DC braking (NC). Stops the motor by
energizing it with a DC current for a certain time period. See P
5.7.4 DC Brake Current % to P 5.7.5 DC Brake Frequency. The
function is only active when the value in P 5.7.3 DC Brake Time is
different from 0. Logic 0⇒DC braking.
Stop inverted function. Generates a stop function when the
selected terminal goes from logic 1 to logic 0. The stop is
performed according to the selected ramp time (P 5.5.4.9 Ramp 2
Accel. Time and P 5.5.4.10 Ramp 2 Decel. Time).
Note: When the frequency converter is at the torque limit and
has received a stop command, it may not stop by itself. To ensure
that the frequency converter stops, configure a digital output to
[27] Torque limit and stop and connect this digital output to a
digital input that is configured as coast.
Select start for a start/stop command. Logic 1=start, logic 0=stop.
The motor starts when a pulse is applied for minimum 4 ms. The
motor stops when stop commands are given.
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 P 5.8.1 Rotation Direction. The function is not active
in process closed loop.
Used for start/stop and for reversing on the same wire. Signals on
start are not allowed at the same time.
Disengage the counterclockwise movement and allows for the
clockwise direction.
Disengage the clockwise movement and allows for the
counterclockwise direction.
Use to activate jog speed. See P 5.9.2 Jog Reference 1.
Shift between external reference and preset reference. It is
assumed that [1] External/preset has been selected in P 5.5.3.5
Reference Function. Logic 0 = external reference active; logic 1=1
of the 8 preset references is active.
Preset reference bits 0, 1, and 2 enable the selection of 1 of the 8
preset references. See Table 65.
